1 12 Embedded C C#, Batch scripting, Powershell scripting None for SW dev. All Windows based - very little Linux experience. System Testing post releases... RTUs (Embedded Systems): - ARM uCs(Atmel & Siliconlabs) Sub GHz, - Small flash & ram - OpenRTOS & FatFS - GNU ARM compiler (arm-none-eabi-gcc) - Ethernet, serial, usb, zigbee interfaces - Dig In & Out, An In & Out, RTD - RTC, GPS - Simply Studio (Silabs), Atmel Studio & Visual Studio. - JLINK - Wireshark - Putty (telnet) - HxD - Git & SVN 11-30 seconds Consistency and commenting is most important. Treat all internal components in a similar manner. Treat all global components in a similar manner. Provide context in names of components. When it serves more than its original purpose - a function should have a purpose and do little more than that. In general though when it is hard to navigate through the components of a function - it is probably too long. There is usually no time for code reviews. 40 20 40 The ability to design, implement and visualize solutions for various protocols and interfaces in complex systems. - Having to go back and fix issues in code that was written by myself or someone else after a long period. Very little. To learn about the principles of TDD in order to ease and speed up design and development of SW & FW. Show
5 months 4 C++ Java, C none Having only just graduated and started working afterwards left me inexperienced. I am considered new to C++ overall however I can manage to work with it. I am completely new to C and embedded systems as well. I do not. No specific target system. QT for c++ 1-5 minutes functions have conventional names, easy to read. When it performs a lot of actions. A function should be short. we trace the parts we are interested in. 70% 0% 30% I like coding, it gives me a challenge. not figuring out the solution of something, and debugging. A colleague. What I think is that I feel like it's necessary to learn about TDD as it may help finding future bugs, and it helps deliver the software early. Show
1 5 java, c++ python, c, none i love learning new things and code and go to the gym i dont . Qt 11-30 seconds the code must be clean so i try to get my code as clean as possible if it do many things and not a single thing mayeb to trace the code all over 70 0 30 To see my program running perfectly and without bugs is so satisfying errors time saving, and can accelerate your productivity so much so that sometimes you need some hardware for the test but with TDD it is much easier to improve my testing in code and save a lot of time Show
5 30 C Python. Have used Javascript, HTML, CSS, C++, Perl, Assembler and PHP in the past. Python unit testing. Into Scifi and currently enjoying season 2 of the Mandalorian. Bespoke Python test harness over the serial port to exercise and validate the running code via a shell. Manual testing by an experience field engineer. Embedded real-time control system for Oil/Gas sampling system. Keil uVision. Linux 5-30 minutes There is no official coding standard, but I try to keep to Misra 2004. When it is too long and you are unable to understand the functionality. Usually aim for around 50 lines max. There is usually only myself working on the code. 50 20 30 Problem solving. Picking up someone elses poorly written/structured code in order to fix a bug. Test driven development, not that much. To learn something and so I can make my code more reliable. Show
0 5 Python Mostly C and Java, however I have also done a little C++. I have some minor exposure to CppUTest through my internship. In addition I have some minor experience with the python unittest framework through my internship. I am a recently graduated computer engineer. In addition to my interest in embedded systems, I am also very interested in machine learning and artificial intelligence. Outside of engineering I love playing sports, and the outdoors. For most of my personal projects I do not employee any unit testing currently. I do not have a specific target system. I use visual studio code for all python programming. I use gcc from the command line and visual studio code for c programming. 31-60 seconds I do not use a specific coding standard for personal projects. But I do use autopep8 for consistent indentation in python projects. In addition I use CamelCase for larger projects. Generally I would say a function is too long if it does more than a single thing. So maybe we are writing a function to do something numerical, and part of that is matrix multiplication. There should be a function that does ONLY matrix multiplication During my internship there was a CI/CD pipeline on our gitbucket server. Each time a push was made it would run all the tests and then you could review any code changes. The whole team reviewed all pushes to the repository at the end of each day. 6 1 3 I like software engineering because I think there is a creative aspect to it. I enjoy STEM topics and I am also pretty creative so I like how sometimes software engineering can combine those two aspects. I do not like the fact that sometimes programming involves spending incredibly large amounts of time debugging code. My understanding is that tdd shifts the process from starting with writing a function and then writing a test; to writing the test first and then writing the corresponding functionality. Using some tdd made finding errors easier during my internship I am attending the training class because it was offered to me, and I am interested in the subject matter. I found the tdd method useful for team programming efficiency during my internship and I would like to learn more about the methodology. Show
0 30 Swift Started on FORTRAN did C for a while, did just a touch of C++ then years of Java with all types of scripting Perl/shell/html etc. lately Swift and iOS. JUnit, touched Nunit; now focusing on Apples XCT Xcode test. I’m a sailor, a dog person, I’m married to Tracy we have no kids and hope to retire soon. Experimentation constantly Much of the last iOS app I wrote was 90% UI and so it was constantly running in simulator. IOS and Mac. Maybe Mac servers. Cloud servers. Xcode What Unix tools I can remember Xcode simulator and instruments tool Under 10 seconds Hmm, I guess it’s following along the lines of a C based std. but way more wordy than the old days. Heck I just had to fix some misspelled words that broke the Apple compiler so bad it gave the wrong error messages When I’ve got to scroll the screen. I’m currently a team of one. Except on a side project. Pair programming with Lance Kind and TDD.Academy. 80 18 2 Building things. That feeling of dopamine when it all comes togeather on a screen. Trying to remember one thousand details that are only needed for this one little bit of code that will be forgotten as soon as I can get it to work right. Kent beck and others invented it to make my life with code so much easier. If only I’d use it -ALL the time. I’m interested in how an expert teaches TDD and all the extras of a hard domain today.

24 46 C++ C, Matlab,bash script (in the past I used FORTRAN, Assembler, Pascal, BASIC) None I studied electronic engineering first and then I got a PhD on robotics. So my education is not on software development. I studied FORTRAN, Assembler and Pascal during my master at the University. Then I studied by self-taught C and C++ and perfected it. Because of this history my C++ skills are not "canonical". My expertize area is on scientific programming and, in particular, in optimization of the code. Optimization is obtained choosing the fastest mathematical algorithms and parallelizing and vectorizing the code. Because of bad experiences in the past I have decided to take this course. I am now mostly working on a 1.8 Mb long code: and I just discovered TDD. I have to implement a testing for this code and learn how to use TDD when I will start to work an a new code. I just test the lines of code I write (trying to do the more exhaustive possible set of conditions) and then I keep the code. I realize this produces, especially on a large software, a code that fails easily and it is difficult to maintain. x86_64 Linux. Code I develop normally needs at least 4 cores to run in real-time (lot of calculations). gcc, cmake and eclipse for C++ (now) 11-30 seconds I don't understand the question. I try to implement a single mathematical algorithm or a single initialization in a routine. But I do not have a criteria. I just know that I do not like to reduce to much the routine length since I found "minced code" difficult to understand. I don't understand the question. Maybe the what follow answers: usually the result of my code are data processing or model software whose results are used on our experiment and/or presented at a conference. I do not have a formal reviewing process. 40 40 20 I like to get a problem from a scientist and solve it with an optimized software. I often get a matlab or a C++ routine and make it run very fast, possibly with more accurate algorithm and results. Re-working many times on the same code (for big changes). This often break the code (now developed without TDD) and the bugs can appear in the worst moments. I only read the googletest tutorial. During an esperimental cruise I got a nasty bugs due to new addition to a code that caused ALL the algorithms, which was running well beforehand, have problems. After asking him, my new software development boss told me about TDD. Show

3 15 C++ 11 Typescript; Java; gtest; junit; FitNesse; I am currently working as a Scrum Master with some focus on technical excellence. I like practising TDD. Every now and then I try ATDD as well. Unfortunately I am not writing much code at the moment. But I try to do my best to get the teams running with TDD and unit testing. At the moment our target system are several micro services within an internal IT department. Mostly IntelliJ for writing Code. GitLab for building and deploying the artefacts. 1-5 minutes We try to stick to four rules of simple design. Some clean code principles like only 5 lines per method. Only two parameters. Intentionally naming of variables, methods, classes and so forth. 5 Lines of Code should be enough. We always try to keep our functions only 5 lines long. We mostly try to do Pair-Programming 20 20 60 I like learning new things. With things I mean e.g. patterns, principles and so on. Last week we did a Kata and tried to only write code based on principles like balanced abstraction, step down rule and so on. I like refactoring of code. I don't like to convince people about TDD. I have read some books about it. "Test driven devlopment by example" - "Acceptance driven development by example". And I try to do my best to practice TDD as much as possible. I would like to see, hear and practice how TDD works from an expert. So not only from the books and self educated. One of my first jobs was about writing code for cashless payment systems. I would so embedded C/C++. So a perfect match. Show
1 2-3 C++ C, Python, Perl None I am a recent graduate of UMBC, University of Maryland, Baltimore County We have a suite of apps that can be deployed for simulation purposes on a Desktop PC as well as on our target system. We develop radar detection systems fighter jet and test against that Visual Studio, UltraEdit, BeyondCompare, MULTI 1-5 minutes Honestly, I'm not very familiar with our coding standard as it hasn't been stressed very much in my time here When I have to constantly refer back to previous sections of the function to determine the flow of the function We don't have a consistent for of code review. Sometimes a senior member of our team will review my code, but usually all of our team contributes their changes to a collective baseline and the baseline is tested overall. 15 20 65 I like the challege of breaking down code to figure out what its doing and I appreciate the ability to create code to serve as a solution to some problem. I don't like the opaqueness of testing, where it can become increasingly difficult to accurately determine where things are going wrong. Not very much I'm interested in hearing about another approach to software development, I also hope to increase my knowledge and develop my expertise in software development processes Show
10+ 10+ C/C++ Java Script None I Have more than 15 years of programming experience but I use the traditional method of debugging. Its mainly functional testing by putting the executable directly in the target board and use printf statements for debugging. Its X86 board with stripped version of Linux ( Ubuntu 10.04). The Kernel is 2.29.6. It has the peripherals ( IOs), LAN Port, Zigbee port Ubuntu 10.04 Eclipse (LUNA) for development For Microcontroller Keil5 and for ARM IAR 1-5 minutes Basic Coding standard 1. When you have to scroll the page 2. More than 100 lines Peer to peer code review is done. Another developer does the code review and put comments in an excel sheet. Modification is done based on that and proper comments are placed in the same excel sheet. 40 30 30 1. Seeing the transformation of idea/requirement to a real life solution 2. My idea controlling something real 3. Taking inputs from real world and giving some out put 1. Hectic schedule/Long hours of work 2. Unrealistic requirement 3. Stress Nothing. It is complete new to me. As I said I follow traditional method of debugging. With the older approach, some scenarios are left undetected in lab testing but appear in field scenario. Want to minimize that so that such situation can be avoided. Reproducing/debugging an issue reported from field is quite difficult. Show
2 4 C++ Python, C, JavaScript, Haskell pytest I enjoy programming and especially in the embedded context. It seems to me quite special to be able to program instruments and small devices. I am new to embedded programing and despite its initial challenges, what I have found most difficult is to organize a decent method of working within this domain. Hardware Prototype in loop, trial and error. 8 bit and 32 bit low end Microcontroller based Instrument Control Systems. These in some cases work in tandem with an Embedded Linux based HMI written in C++/Qt. STM32Cube, Viusal Studio Code, Visual Studio, Qt Creator, Vim Under 10 seconds C++ coding standard guidelines If a function does more than one thing, or if it mixes pure computation and IO, I try to separate them. No review process in place. Static analysis tools - not in embedded. 10 30 60 Building Abstractions that lift the semantics of the code closer to the domain of the project. As project size increases, new requirements are brought in - things can start becoming quite complex due to the hidden dependencies they have on each other. I understand its (immense) usefulness and do depend on tests to have confidence in the code I have written. However, I do no know of testing outside of Unit tests. I had a really bad experience on the previous project. I don't want to be in such a position again where my code is so fragile. Needing hardware in loop when programming embedded systems - I would like get out of this. Show

3 10 C/C++ C#,Powershell Google Test I love writing code, I love Operating systems and system level programming. I'm very curios person and I like to understand everything is details. yes Windows Low Level System Programming, Device Driver and System level code C/C++,git,tc, Visual Studio 1-5 minutes I like to use modern C++, use the STL as much as possible. If I have to scroll to see the full function It it is doing more than 1 thing. Code review needs to be reviewed and approved by 2 people. 50 25 25 That I can design and implement something from scratch. Getting the computer to do exactly what you want is awesome. I love solving problems. Having to deal with old legacy systems that I do not fully understand. It helps developing software in small increments and it shortens the time to between writing a bug and finding/fixing the bug. Because I want to learn more about TDD Show
2.5 10 C and C++ Pyhton (novice), Shell scripting gtest - Have programmed for embedded, driver and middleware components for Android/Linux, Symbian and Windows platform primarily in C and C++. - Have written some unit tests using gtest along with custom mocks/gmock, component tests and system tests. - Like to improve testing skills to find better bugs and vulnerabilities - Unit test using gtest (most of new code, some legacy) - Component tests e.g. client/server, COM client/component - Automated system tests using proprietary automation framework. Mostly regression, updated when a new feature changes some system aspect - Manual testing. Uncover more feature specific end-to-end test - Performance and stress testing using industry standard tests for enterprise e.g. LoginVSI for single server scalability Windows on X86 Microsoft visual studio (MSVC++), Trace tools (based on windows event trace logging system), build scripts using power shell, Windows debugger(WinDbg), Wireshark, git 1-5 minutes Mostly uses standard C/C++ coding conventions - Function seems to do much more than stated purpose - Is too big (lines of code) - Has too much nesting (cyclomatic complexity) Code reviews are done using review tools (Atlassian bitbucket), requiring at least two human approvals one of which is generally required from SME. An additional bot "reviews" for build success and automated smoke/sanity tests's success 35 30 35 - Great to design systems - Great to implement systems - Satisfying to make code do expected - Learn new technologies and ways - Understand systems how they work and solve issues (sort of puzzle solving) - Delivering value to customers - Legacy code and maintenance - When new to a complex system in place it is difficult to balance between requirements and efficiency and understand big picture (however it feels good to overcome these and understand the system) - Effort estimation Very little - Name, and that it is different approach where tests are developed early based on requirement unlike traditional approach. These tests are used as sort of specification to ensure code meets the requirement. - Want to see if there are better and more efficient ways of doing tests - TDD sounds fascinating and curious how we can develop tests so early Show

4 20 C++ Java, Kotlin, Ruby, JavaScript Google Test, CppUTest, JUnit I see a trend that most mainstream programming languages are adopting functional programming features into their languages. I'm in the process of trying to learn more about functional programming and think it might be good to use in combination with TDD. I spend most of my time testing by writing unit tests to verify the code under test is doing what I expect. Next I test the code in production to verify it's working as expected when integrated with the rest of the system. Currently writing software that runs on multiple platforms. We have to make sure we can write as much cross platform code as possible so that the same code can be reused on all platforms. Visual Studio, Visual Studio Code, Android Studio, Clang, CMake, Git, Windows Terminal, Docker, Windows Subsystem for Linux 11-30 seconds We try to keep our tools up to date with the latest standards and use C++17. We encourage our developers to use the modern features of the language to improve code clarity, such as using smart pointers instead of manually managing memory. I feel like a good way to tell if a function is too long is if it violates the Single Responsibility Principle. Everyone on our domain team gets added to the code review and is free to comment any suggestions. Two developers need to approve the code review before it gets submitted into main branch. 40 20 40 I like that programming gives us the ability to create so many great things and all you need is your computer. Trying to figure out the root cause of a software bug that is intermittent can be frustrating. TDD is a test first approach to writing software. You write the unit test first before any production code is created. This has the advantage of never having to submit production code without tests and also improves the design of the code. I've taken this TDD class, but many years ago. I think taking this class again will remind me of the all concepts I learned in the past and give me extra insight to apply them better. Show

4 6 C++ C gtest and gmock I am fairly new to Object oriented programming and part of a team which is tightly coupled with MS subsystem. I am part of protocol team as well which is predominantly client-server architecture both on the same machine as well as over the network with multiple components (named pipes, network socket, COM etc) Wherever possible and wherever there's an ROI, for all new code, we write unit tests and legacy code predominantly gets tested at system level Target system is Windows 10 or 2016 VDA connecting with a client (windows, mac etc) and running along with multiple components in the middle interacting with each other at various times. Visual Studio, Sublime 30-60 minutes Beginner with clear and readable code. Keeping code as simple and efficient as possible. Write a lot of comments where ever possible. When multiple independent operations are clubbed together Looking at working as well as readability of code along with avoiding static analysis errors. 5 3 2 Amount of learning involved and how designs and concepts are so beautiful. Gives the jitter on anything new that I take up. Best thing is, we can work from anywhere :) I love the variety of things that can be done. sitting in front of the computer all day :) Writing code with testability in mind, not just writing tests before writing code To learn and adapt wherever possible and wherever it makes sense to invest Show
12 since 2005 C C++, little bit of python and C# googletest I prefer to follow a pragmatic approach to software engineering and development, exploration and experimentation. mix of automation, unit test, component test and manually. depends...it could be linux or windows, simple or complex deployment VS Code, Visual studio, git bitbucket 5-30 minutes short functions, no global variables, simple solutions and code obvious to understand nested control structures, duplicate code, unnecessary overhead, having multiple responsibilities, depends... Understand what problem this code change addressing and how. Flow of the code and data. Avoid or minimize use of global, local variables. Error handling, resource cleanup, return values and parameters to functions, their time etc. 40 20 40 Problem solving, to be able to synthesize thought/idea to real world code. too much context switching Write failing test case and let it fail, then write the (production) code that makes it pass. I am convinced with the value and importance of Test driven development. To consciously develop the mindset needed to apply TDD skills in every day operations. Show
2 19 C++ Python, Go, C Unity, GoogleTest Wes Montgomery is my favourite guitarist. GoogleTest - I have unit tests integrated in some parts of some projects, but an uphill battle to incorporate it int Mostly XMOS MCUs or embedded Linux targets. gcc, vim, CMake 1-5 minutes Working towards adopting and formalising one More than two screens. Many of them are too long anyway. Upsource - we have a language-agnostic set of acceptance criteria 30 30 40 Working through obscurity and indecision to develop a working, well-crafted system is really satisfying. Gumption traps are acutely painful. In principle, it structures development activity as a short feedback loop within a rigid and supportive mental model. In practice, it tends to encourage implementing programs as assemblies of implementations-with-interfaces. When I've been able to use it (i.e. in C++), it's been a really satisfying workflow. I want to discover good ways to introduce it into C-based development, and to gather ideas for adapting legacy code so that tests can be added. Show
4 20 C++ C, XC (for XMOS), Python, bash, Groovy Googletest Probably the thing about me most pertinent to this training is that I largely work with what Michael Feathers refers to as a large legacy codebase. There are a number of ways and it varies. New code is generally developed along with unit tests - these run as part of the build on the CI system. The unit tests either run the code natively on Windows/macOS or use a simulator for hardware specific functionality. There is an automated test harness using real hardware for end-to-end/integration tests. We have some great QA engineers who do manual testing and who develop automated tests. I do some manual testing while developing the code. I work with a legacy codebase and some of these testing methods have been relatively recently adopted - a lot of code is not under test... USB, XMOS processor, audio, real-time. VSCode, git, XMOS toolchain (including XGDB), xTag debugger, GoogleTest, lots of bash, Beagle USB analyser, Jenkins, Artifactory, YouTrack, make, cmake 31-60 seconds We're currently discussing coding standard across the company - there isn't one currently in place. I feel like I could look this up and give you a technically correct answer. In practice, a function is too long when I can't keep all the context in my head, or when it does more than one thing, or maybe more than 50 lines. It varies. Code reviews vary from meetings to discuss the approach taken to fix a particular issue to using UpSource or using merge requests in GitLab. They vary from project to project and the availability of appropriate reviewers. 20% 20% 50% Building things, getting things done, problem solving, helping people. Feeling there is not enough time / resourcing. I have heard about it on podcasts, I have read a couple of books, I used it in a project (which went well) and I enjoyed the rhythm of TDD. I first heard you (James Grenning) on the Embedded.fm podcast, I have your book, I have used TDD before (it went well and I would like to use it again) and I want to learn how to use TDD more effectively. It should also help management buy-in. Show
4 7 C++ C#, C, Python, Java Jenkins We mainly use C++ at work, but this is my least used language used in school. A lot of our effort right now are expanding our unit test support, so I figured this would be a great opportunity to learn more about C++ and testing our code. Run scripts through Jenkins each night. N/A Eclipse 1-5 minutes Well defined. The code is the main reference for coding standards but we do have documentations somewhere.... Usually when you have to scroll to see the what the whole function does is usually a sign to start breaking the code out into smaller methods. This is very situational though, sometimes it's hard to avoid. Usually one on one meetings stepping through the code. Sometimes we have larger groups (around 5 people) stepping through each line. 4 2 4 I love problem solving and challenging my brain. Documentation/Commenting. Setting up an environment. nothing! I just finished college and looking to expand my knowledge and contribute more to our team. Show
0 8 Matlab/C C, C++, Python, C#, Mathematica I don't know their names. I'm a GNC software engineer, so my primary IDE is Matlab. I'm interested to see how what you teach transfers to that environment. There is an existing unit test structure in the C code, but nothing implemented in Matlab. My target is an autopilot. Matlab, Visual Studio Code 1-5 minutes There is no written standard, I try and keep things as simple and consistent as possible. If a function is doing more than one thing (within reason) then it's too long. I'm less focused on length and more on content, but I think being focused on the latter has a tendency to control the former. They are good-natured and useful. Sometimes the points are pedantic but I would say they are useful more often than not. 50 10 40 It's the laziest form of building you can do, and I love to build things. Working with legacy code. I think the point is to write tests first and then write code only until the tests pass. It's required by my work. Show
5 3 C Python Working on C++ None in practice - have seen Unity and GoogleTest I'm a electronics and firmware engineer - I do a split of hardware and software work, the software stuff has come in more in the last 3 years. I also do quite a lot supporting DevOps activities in the teams. Verifying behaviour using memory-watching while stepping through (with code running on the target), logging trace events, and functional system testing on the hardware. STM32 Cortex-M devices (M0 through to M7). Starting to work with Espressif ESP32 devices (Xtensa core). IAR Embedded Workbench, VS Code and CLion for IDE / text editing etc. GCC and IAR compilers. Segger J-Link, IAR I-Jet hardware debuggers. 11-30 seconds Be consistent and fit in with what you observe of the standards already in the codebase. We don't have anything formalised! When I can't keep track of the mental model of what's going on anymore, or it becomes obvious that the function is handling more than one job. We peer-review design documents as part of our process. Code reviews are initiated by the code author when they feel its needed (which happens for maybe 10-25% of the code). 40 10 50 It's open-ended, there's the opportunity to be creative. There's a craft to it - you can go a long way further than having code that functions as required, and have code that is transparently written, reusable and efficient. It's open-ended, and the number of techniques, design patterns etc can be overwhelming! It's hard to estimate time. It's hard to estimate how powerful the target CPU needs to be! It's an extreme programming concept. It's related to but not the same as unit tests. You write a failing test first, then make it pass. I want to get a practical start in writing unit tests, and get better at preventing bugs. If the process of TDD is a good way to do that, I'm up for it! Show
0 1 C# Python, JavaScript, HTML None Recently completed a 14-week intense full-stack coding bootcamp that focused on Front-End, Back-End and Database in Python/Django, C#/ASP.NET and MERN. I haven't I don't have one Visual Studio Code, the Internet Under 10 seconds n/a n/a n/a 0 0 0 I like building out the application, little by little adding features and getting them to work successfully and creatively and then finally having a functioning program that can be seen or interacted with on the user side. Not knowing how to approach something or wrestling with errors once I've written code and can sometimes spend hours trying to fix it. Just that it stands for Test-Driven Development and that it seems extremely tedious but necessary to vet software for complete viability. First, because of a referral through Tom Stanton. Second, because I feel that I can't have too many tools in my developer's arsenal. Show
1 39 C Python CppUTest My company serves various retail industries in IoT. Earlier I worked for a German safety equipment manufacturing company to develop gas monitors for about 25 years. I enjoyed studying & using Humphrey's PSP there to gauge and improve my work quality. I've also enjoyed reading about TDD through your book. I used CppUTest on the job a couple of years ago for testing MSP430 C code, on target via a simulator. We test using manual device and system tests.

New to company, they use CPPUnit. Past company we tested per requirements on a hardware rig, then we had a validation/test group that did formal testing, using custom scripting / hardware to exercise the software.

One is when unit testing, there are several different disparate outputs and output paths - in other words, it doesn't do just one thing.

(Compiling and other tools are used by senior members of my team.) 1-5 minutes I typically follow a very academic coding standard with commented documentation. Being new to professional development i as still learning how professional may be different than what is expected of students For me it depends on the system we are developing for. Embedded systems have very limited resources often times so function call overhead cannot be too large so functions can be quite long. the opposite is true for less resource restricted systems. I haven't been a part of an official code review yet in my position. Any code reviews I did in school were more focused on getting code working than making it more efficient or better overall. 50 20 30 The challenge that comes along with using a rudimentary set of tools to accomplish complex tasks, its like using simple machines to create complex machines to accomplish a task.

When I have to fight the development environment, debugger, etc. I also don't like when I have a vague requirement on what I'm being told to do and have to guess at what the customer or product owner want Not much, I've heard it's a paradigm shift in that you think/write the tests first before writing the software I have an interest in this and it's corporate provided training which makes it easy to take and pay for.

My new position is almost entirely embedded software focused. I definitely have a lot to learn, and would like to be able to work faster. Before ceedling I'd often test code using print statements or toggle pins if testing on hardware. For timing critical testing I might throw test data into an array and print it all at the end. But that took a bit of extra work and system overhead. I really like Notepad++ 11-30 seconds My team uses a modified version of the Barr group's Embedded C Coding Standard. We kept most of the rules with technical rational and modified the more subjective stuff. I try to build functions that do only one thing.

Before reading your book I was writing code, building the code, pushing the code on the target and verifying in debug mode that the code I just wrote was working as intended. After reading your book I started to use ceedling to unit test my code. So now I'm coding and testing my code on the computer and when a bunch of module are ready to work together I to the same as previously but with less step by step debugging and more global verification like verifying the outputs with oscilloscope or logic analyser.

Maintaining legacy code can be challenging when there are no automated tests set up. I have read and use your "TDD for embedded systems" book as a reference. However in practice, only one of my projects followed TDD and that was because it was primarily algorithm implementation (pre-determined golden references for all inputs).

My first curly-brace language was C++, which I programmed in for many years. I've never needed to build a system in C from scratch, and usually reach for C++ if that's an option. Unit tests where possible, running off target. I've tried using drivers, and test doubles, but found it difficult in C. I'm not normally doing embedded outside of hobby projects. Most of the embedded programming I've done is AVR ATMega based using the gcc-avr toolchain. I've tinkered a bit with STM32. In this context, gcc CLion, CMake. 31-60 seconds n/a When it fulfils more than one purpose without delegating to other functions. Ad hoc. 50 30 20 I enjoy solving difficult problems. Occasionally I'm good at it. Hard to reproduce bugs. Red, green, refactor! I practice TDD when I'm uncertain about the direction I want to take. To learn about how to deliver training over the Internet, with strong curiosity about how the pros do embedded programming. Show
0.5 25 C C++ Java Gtest XUnit Junit I have been a mainframe programmer for a long time before my current job, so I'm used to working with a tool chain that is a couple of decades less "modern" than what most developers are used to. I'm also used to having to spend a substantial amount of time, making very different systems talk to each other. When working from a spec, often there is an official test vector set that can be used for validation. Sometimes there is an alternative implementation for a different piece of hardware that can be used for reference. If neither is the case, Various hardware security modules (HSM's) programmed in C or C++. We develop code in MSVS, but each target has its own proprietary C compiler, usually building in a Linux Docker image. Compiled binaries are then hand-loaded onto the target platform. MSVS IntelliJ 1-5 minutes We have internal coding standard that focuses on correctness and security of our software. I have been part of organizations that spent a lot of time on natural language, but in my opinion that has mostly been a waste, so I much prefer readable code. When I can't see the whole thing in a standard text window, or when the list of parameters contains multiple optionals controlling multiple code paths inside the function. In my opinion, code review is more about sharing knowledge than anything else. You can have great discussions about architecture and style, but it is uncommon for bugs to be found in the review process. 30 50 20 I like the art of imagining something inside my mind, and eventually prove it is logically consistent. I dislike working overtime trying to finish multiple projects with the same deadline. Especially when there is never time to consolidate/refactor an old codebase, but always time patch systems that have not been properly maintained. My experience has been that it works great when using the most modern/mainstream toolchains. When using older tools, it's much more of a chore, and so requires much more discipline to do. I'm new to the team, and some of the other team members have recommended the class. Also, some of the coding standards and development processes adopted by the team are inspired by the course - so it makes sence for me to adopt as well. Show
6 21 C++ C, Ruby, C# CppUnitTest for testing embedded C code.... 10 years Doing embedded SW in a real world with users, step motors, mechanics and other things, which imposes a lot of challenges. I Live North of Copenhagen in small village with my wife and two kids (8,10). Rides mountainbike and is chairman of Trailbuilding group Apllication code: Simple intergration test, but nothing automated. In the present team we are 3 embedded developers and 4 PC application developers. Two testers, one manager, a PO and a SW project manager Platform code: cppunit test of some parts of the code base Embedded system for Food analysis NXP LPC4357 with multiple modules internal CAN communication 480*800 touch display SQLite database Data upload to a Foss Cloud solution Green Hills Multi 7.1.6 compiler and debugger Visaul Studio 2017 as IDE and simulator Ues "Rant" for building 5-30 minutes what???? Nothing formalized and no static check besides the compiler When it is hard to understand and the function uses global/external data. All code is reviewed, since last summer. The current project has run since late 2017 :-/ We use Azure Devops and I am quite happy with the this 30 40 30 Solving problems in a real world with many different and complex inputs Finding bugs, repeating coding erros, finding errors made by others I have read "The Book" (and lost it) Heard several of the embedded.fm podcasts, where you particiate I hate making erros and hate event more finding erros mad by others. I want to spend my time being productive while trying to ship fewer errors. I want like some kind of defensive measure, which helps me in find my own errors early. Show
3 5 C/C++ Python None I have been involved with the algorithm team in my company and I hope someday that I will be competent enough not only to develop software, but to be involved in the algorithm development too. Manual Mostly ARM ATMEL Studio, Keil, MATLAB and Simulink 31-60 seconds NONE. But I'm currently working to adopt the ISO standard for C++ When it does more than one thing The design is reviewed with the software architect. I use sonarCube to verify the code 3/10 2/10 5/10 I like when Software are developed to be SOFT. Easy to change and reusable in different hardware. It takes to much to debug the code. Especially when there is no hardware available to test on. Testing and Development grow together. Write the test first, then write the production code. I have been having a difficulties with testing in general when developing embedded software. It takes so much time to test. Show
2 3 C c, python, c++ Automated tests Looking for improving my software skills. Manually updating impute values for a function and compare the output values with the expected ones.

19 >25 C C++ C# Java gtest cpputest aceunit junit We write code both for embedded systems as well as code for communicating with these systems. The code integrates with headers/libraries, and is build using the compiler and toolchain supplied/endorsed by the vendor. The architecture of the code is usually composed of an abstraction layer covering the differences between the various platforms and an application layer that is (should be) neutral to the platform. The tests are partly unit tests and partly functional tests. Unit tests are run off-target. Functional tests on target. Test of algorithmic code and code integrating with the libraries offered by the vendor is tested on target. This approach has been chosen to ensure that differences in endianness, size of basic data types etc are sufficiently covered by tests. The target systems are based on a number of different architectures. In general, debugging support is lacking - commonly reduced to output only when execution of the code returns 'nicely'. Mainly Microsoft Visual Studio, gcc & IntelliJ 5-30 minutes Not formally. We try to avoid pointer arithmetic by writing functions encapsulating that kind of operations. Then we 'only' have to test those function to avoid many of the common pointer & overflow pitfalls. Do I have enough fingers to count the statements? ;-) -more seriously, all statements in a function should be at the same abstraction level and the function should so simple that a) no unit tests are needed or b) unit tests should be simple to write Code is reviewed by a colleague - sometimes by the colleague sole - othertimes as show-and-tell seances. 3/10 3/10 2/10 Making stuff work. Debugging and Maintaining documentation Some prior knowledge - Have tried practicing TDD and have read (parts of) your book "Test-Driven Development for Embedded C" * To get a common language regarding test and code in our team * To get a common understanding on good/bad tests in our team * To refresh on TDD habits Show
10 16 C Java, C++, C# CppUtest, googletest, aceunit I love to make things easier, more efficient and more fun. I like sharing my skills and knowledge and seeing people improve in all areas of life. * TDD unit testing for small well defined functionality. * Using a software implementation of the hardware abstraction layer. Hardware Security Modules of various brands and different CPU architectures with down to 1MB RAM. The same code has to work on all platforms, therefore all code is written in C. Visual Studio, IntelliJ IDEA 5-30 minutes We are in the process of developing some common code guidelines. Before, the primary focus has been on making readable code that clearly signals what is going on. In addition some unwritten rules about how to program defensively. When it is hard to give it a concise name that describes exactly what it does and nothing more. Code reviews should make sure: * The intended task has been done and that nothing is missing * Relevant tests are present * The code is: - Secure and follows guidelines - Easy to understand - In the right place - Better than it was before 70% 20% 10% Solving problems "automatically" or more efficient. Seeing new functionality work, seeing something run faster. That I can make working with something feel good/better. Sometimes you are forced to create solutions that you are not proud of. I did the TDD online course some years ago and have been teaching the rest of the team some of the principles. To refresh my knowledge on TDD and because I want the team to have a common understanding of the principles and values of TDD. Show
