<1 5 C C++,Python None I just started my job 6 months ago from college so I'm trying to develop good habits! I read your book and loved it, so I want to start implementing it into how I work. Using either our test scripts on our emulators or through stepping through the debugger to see our values are what we expect them to be (which has been a painful way to test) We use an ARC based processor which has 2 cores and a finicky debugger. It uses a ccac compiler Jenkins, parasoft, Metaware (eclipse based IDE) 5-30 minutes Haha wish I knew, I don't think this is strictly defined in our group. Visual inspection, if it looks too complicated, you need to scroll down, etc. I've only been here for 7-8 months. Haven't had a code review yet- I know it happens though. 2 5 3 I like coding and solving difficult problems. I also like fixing bugs. Being deep in the debugging process and not knowing what to do resolve it. It is incremental and about not writing code that doesn't have a test(I've read your book) I read your book and I want to learn how to implement your concepts in my daily work Show

18 40 C C++, Ada 95 (!), Assembly (rare) Home-grown (my own) I have been developing on embedded systems & protocols nearly my entire career. I've been so focused on work the last 10+ years and been surprised by Git, DevOps, and Rust, e.g. I have some catching up to do - including with test frameworks and TDD. I use debug trace statements to follow the execution path and, when needed, log variable values. I use a tool to send messages to exercise the paths/features I'm interested in. Such testing is not readily repeatable. ARM M3/M4 MCUs controlling some discretes & peripherals (Bluetooth, USB, I2C, SPI). Soft real-time.

2 10 C/C++ Python, Java, C#, and Javascript Most experienced with Java/C# Junit a little bit, but primarily have not done unit testing Outside of my embedded day job, I like to work on mobile and cloud computing side projects. When I'm not programming I enjoy traveling and playing board games & video games. Not in a systematic way. Pass in extreme values to the function and verify I get what I expect. I step through the logic with each expected value (usually by "hand") and then work through it to verify it's correct. Primarily 32 bit ARM Cortex-M MCUs IAR 1-5 minutes We pretty closely follow the Embedded C Coding Standard written by Michael Barr. If it does more than one thing, break it up into smaller functions. Long funcs usually do too much. Mostly informal - with a few other software devs reviewing the code and walking through it. 40% 20% 40% Debugging. I like trying to figure out what's wrong with the code. I also like building new things. Analysis Paralysis. It's easy for me to spend too much time trying to find the best architecture.

Each one has a forth interpreter exposed via a UART. IAR, gcc, clang, make, Jenkins 30-60 minutes Well... I'd love to... if we had one. When I can no longer keep up with all the code paths in it. Time to refactor. Peer review per code change. 10 50 40 The challenge of making code truly reusable. Not just salvagable but reusable without change. The short schedules to achieve unreasonable accomplishments you should define your code with test cases before implementation whenever possible To see if my ideas of TDD match up with industry standards and scoff at the deltas :) Show

2 15 C C++ None Taking a risk-based approach to developing device software reminds me of previous experience mountaineering. I also find that association amusing. Our testing is done manually. Manually writing test cases for functions and modules. Arm Cortex-M4, mainly STM32F4s Keil uVision MDK, Parasoft C/C++ Test 30-60 minutes Currently undefined for the organization. Trying to st When I need to scroll up or down to find relevant portions of information within the function, it's cause for me to reconsider if anything done in the function is needs to be moved into its own function. Reviews are done during pull requests of our git-based repository. 30 40 30 When approached properly, developing software can be intentional and deliberate to produce amazing things the world has never seen before. The misconception by other groups in multifunctional teams that developing software is quick and easy. It is quite easy to walk down the wrong path and write software quickly and haphazardly to produce code that functions for only "right now". I know that it relies to requirements as its pillars and testing against these requirements to consistently produce functional and purposeful code. In previous organizations I've worked, there wasn't a focus on testing. My co-worker shared 'Test-Driven Development for Embedded C' when he joined the org and I ended up purchasing a copy. After found this training while looking for more resources. Show
5 ~10 C, C++ Ruby Python Rust Check - C CUnit - C CxxTest - C++ Boost::UnitTest - C++ Rust - built in to the language! Isn't just having your Python/Ruby script run without exception enough of a test? I really enjoy music - both listening and recording. Since I also like writing programs for embedded systems, I have written a program for a Raspberry Pi that will rate the quality of a vinyl record on a scale of 1-10. I sometimes enjoy writing python scripts that generate music that only a computer could reproduce, but the music generated is never good. C production code is tested using CUnit. We chose this library because it was very easy to compile with our custom toolchain and does not require an OS. C++ production code is tested with CxxTest. We chose this library because the python script that auto generates the test harness is easy to configure for use without an OS. All unit tests are run on the target system. This allows us to unit test things like GPIO assertions and interrupt handlers. SoC with a custom MIPS processor. Custom C and C++ compiler and toolchain (gcc patch). CMake for defining the build rules, which generate Makefiles we use for building. CUnit for C unit testing. CxxTest for C++ unit testing. Emacs 1-5 minutes We don't really have a coding standard. We use CodeSonar as a static source code analyzer/linter/good practices checker. If it can be made shorter and clearer. If it would be better split up into two or more separate functions. If it is a reroll of std::find. If it is a reroll of std::accumulate. If it is a reroll of std::transform or std::for_each. Usually involve 4-6 reviewers, each reviewer spends 2 weeks annotating the code. We use a custom tool that allows reviewers to collaborate and make in-line annotations without modifying the code. 50% 40% 10% Software is really about automating things. It's about spending x amount of time today to save yourself and others 10x amount of time or more in the future. My favorite thing about software is the feeling of time saved. I'm not convinced documentation is as important as everyone says it is. When there's too much, there's a sense of ease but you often miss the important parts. When there's not enough, there's a sense of panic but you can always elaborate more. *Write tests before you write code. *Unit testing should be able to hit ~100% code coverage. *Tests should follow the setup, act, assert pattern. *Unit tests should never depend on test ordering. *Test feedback should be immediate and readable. I'm interested in TDD, and especially interested in bringing it to embedded systems programmers. I've used it in my projects, and have had success bringing it to my group, but I want something to be a success story for TDD in other projects. Show

17 10 Java C/C++ None I have spent the last 17 years working as a Sales Engineer where my programming duties were 1/4 of my workload mostly centered around developing SW to automate testing of HW, creating demo/POC applications to reveal ROI of business use cases for HW/SW solutions, and creating demos for development teams. Recently I accepted a position with Engineering as a full-time Firmware/Software Engineer, this recent move will allow me to build upon the basic programming experiences that I have had to date. So some concepts of this course will be new to me and I am eager to jump in and learn. I have a BS in Computer/Science and Engineering. I generate a test plan independent of the SW project based on user requirements/use-cases and then manually create a test document to run the SW through the tests x86/ARM Visual Studio, Eclipse, Android Studio 1-5 minutes I try to write code in a way that is easy to understand avoiding additional complexity when it is not needed for efficiencies and also making use of models/patterns. Also, I tend to test frequently to keep debugging complexity low.

Never change the coding style of an existing file. If comments are needed which are not related to a single line. Very useful. The skill is to invite people which are able to give useful feedback. 20 60 20 It is creative. If time or money are wasted for any reason. The idea is quite obvious. It is not the only but maybe the best way to get meaningful unit test cases. I would rate this a helpful if code is under your control. It is difficult to apply if only minor changes are added to a suppliers code. I get the chance to do this. Being a senior engineer team members ask me each day for help.

0 10 Rust C, C++, Python Cargo, CMake (ctest), gtest, gmock I also work on open source Rust crates I typically add unit and integration tests when I am working on something that could have runtime errors that could result from my code, like parsers, algorithms, etc. In Rust I often avoid writing tests by using the type system to make certain error cases impossible. I typically develop on Ubuntu, but I recently got a Mac with Apple Silicon, and I also use Windows. Basically, everything. I typically use VS Code + Rust Analyzer + Cargo. 11-30 seconds I like to see the open source ecosystem reused where appropriate and contributions upstream rather than internal forks. If it is hard to read because the comments and code aren't sufficiently high-level to make reading easy then it should be split to improve code readability. We often develop in a mob, allowing for live code review. 80 15 5 If we develop reusable, clean, and maintainable software, it can be evergreen and build upon the existing work of others to get us to a higher level of coding abstraction. I don't like when coding is performed without a plan for the overall architecture and code reuse. I am familiar with the process of writing tests in advance and making incremental changes to avoid getting ahead of yourself. I only do it when I am trying to implement something that is non-trivial. For work and to learn =) Show
Half Year 6 Python C, C++ Pytest I'm a relatively junior engineer and am interested in learning how to develop software more efficiently and cleanly. Using some flavor of test driven development.

Tends to depend on the situation and the project I'm adapting to working on. When it does more than the functions purpose. Currently depends on the project, but generally pretty high-level. 60 20 20 There are endless ways to approach many problems, there's satisfaction in doing it well. It isn't all exciting- keeping up on new standards and methodologies can be hard to do. Nothing officially, just a general understanding of the design methodology from some books.

After a year, I started to work with SoC (VHDL + Embedded Linux + C programming), where I spent 2 years. Nowadays I work mainly with C for embedded environments. For newly created software units, unit tests are applied during development ( first the logic is implemented, then tested). For legacy code, tests are done by looking at the integration level. Low power Microcontroller 32-bits. Eclipse, IAR , Visual studio, azdo, EA.

It's nice to see changes in software map to changes in real life. Debugging. Sure, I might be the same as the majority (as stated in the intro video), but, yeah, the abyss of debugging can sometimes be a little deep. Write the test first, watch it fail (red), make it pass (green), and then improve it (refactor). Start from the simplest possible tests. Make it pass in the most direct way. Mandatory by the company. I'm also personally invested as TDD is a standard we've been using and I'd like official training on it to improve my understanding. Show

As a DevOps engineer I mostly write scripts, and then by executing the script, I would see, wether the script works as expected or not. (In my side projects I use gtest and the Visual Studio native unit test framework, and the debugger) n/a GitHub, Docker, Azure 1-2 hours MISRAC2012 Deeply nested control structures and when you cannot determine the purpose of the function in a reasonable time Done through pair coding and at the pull requests 50 30 20 Complex challenge Finding errors/bugs The idea behind it is clear, but I have never used this approach before. There was a single free slot, and it is a class, where I can learn a lot. I have been working at Siemens also on the automatisation of the debugger and had to use code coverage to generate IDS rules, but TDD is new to me. Show
2 1 1/2 Python LabVIEW, C++ PyTest, UnitTest I am an Electrical Engineering graduate who shifted into Verification work and enjoys it more than what came before it. Programming was once a dreaded thing to practice but has become one of my favorite things to do. PyTest, UnitTest, other test API, and trial and error I am currently developing test software using a Windows 10 Lenovo x64 machine, but plan to create tests to be deployed and triggered on Raspberry Pi 4's for actual CDCI. Visual Studio Code IDE, Thonny IDE (for Pi Pico or lightweight Pi 4 work), GitHub Actions 1-5 minutes I am usually writing interface code for equipment that's later tested so a standard is that regardless of the protocol being used on the equipment, we name our functions similarly. By doing this we basically know all functions for all equipment. When it does more than one thing towards the target. I do not have code reviews as a Verification Technician. 40 40 20 Being able to create something very specific for an custom application. Later being able to modify my programs and reuse them for an entirely different application but slowly building a collection of personal libraries that make my job easier. Packaging, setting up environments, and troubleshooting something to later realize the problem was somewhere else. Off the top of my head, I understand it to be the practice of consistently testing every other line of code you write assuming everything is a modular piece. R&D Director (at the time, he is no longer with us), encouraged that the Verification Team attend along side the the Development Team due to how valuable it could be for overall progress made. Show

There is always plenty of opportunity to learn, either through your own research or through courses. The search for the cause of an annoying bug that is almost impossible to find out about.

Code reviews are done in Pull Requests of Azure Dev Ops by a technical leader. As a basis there are review report templates bound to our internal processes. 30 20 50 I like that there are almost no limits of what you can do. I made the experience that even if you think you got the best solution for something, there is another guy around the corner which has a better solution for it ;) Due to the fact that a lot of people belive that software can always and at any time be changed easily there are most of the time a lot of changes during development. I do not like to fight with a fragmented software that grows and grows. There was once a motivation in the team to switch so i bought actually your book and tried it out in small examples. But it never made it "fully" to the project. What i tried to keep for me is to think first about what i really want before coding. In my small exercices with TDD i saw the benefit of thinking about testing in advance to not get untestable code in the end. It even influenced the way to design software items. I would like to get a deeper knowledge ecspeccialy when it comes to HW. Show
1/2 3 C C++, Python No unit test harness used in the past. Rudimental steps with CPPUTEST done. I have a background of mechantronics and electrical engineering, but during studies always focused on the "hardware/software interface". I don't have much experience of nice greenfield SW development (e.g. creating a SW Module from scratch). But I consider myself to have good debugging skills, as I worked in a very late stage project in the atuomotive area, where had a lot of bugs and little knowledge about the ideas behind different implementations. We are at the moment in the setup phase of our project. We plan to use Google Test for Unit tests. And we want to have automated integration tests by using Robot Framework. In my past projects testing was mainly done directly after implementation, but for my feeling mainly rudimental tests. There was a seperate System Test deparment. Embedded platform for ethernet fieldbuses. The plan is to use C++ where possible. Static Code Analysis Azure DevOps 31-60 seconds Plan ist to apply naming conventions according to "Clean Code" for example. Technically we want to conform to MISRA C and AUTOSAR C++ Guidelines It doesnt fit on the screen anymore. Currently in setup phase of the project and no fixed process is implemented so far. 40 20 40 The whole workflow from simple requirements to functional products. I also like the complexity of the whole topic. From build environments over source control to actual coding. It is hard to tell if a the way we choose to do things will be considered as a good decision in the future. SW modules always seem to be fine in the beginning as long as they are small and the person who created is available. That it is a really different approach of development, where you have to get used to it. It is one of our best shots to create maintainable software It is part of the companies strategy to allign the development approach, therefore it is mandatory for every new developer. I'm glad about that, as it is hard to convince a non-software aware manager of the importance of such a training :) Show
8-ish 40-ish C++ these days C, Java (and long time ago, Lisp) CppUTest I'm passionate about developing quality software, done "right" the first time so it can be used forever. What better way to save time than to reuse software you know you can trust? Unit tests are executed during the build. Higher-level tests are still largely manual and/or ad-hoc. I'm seeking to improve this at the organizational level. Military vehicles, ranging from microcontrollers to desktop-level machines. Eclipse. 11-30 seconds It's centered more around good software practices than syntax. When it's doing more than one thing (although "thing" isn't easy to define in this context). We need better participation. Authors need to do a better job making it easier for others to participate. We also fundamentally need to reduce the need for them by adopting better, more modern practices that include a lot more testing. 60 20 20 The creativeness of a good design. Technical brainstorming sessions. Communicating verbally with others. Maintaining poorly-written software. Throwing documents over the wall. Doing anything that doesn't add value. My understanding is it's based on tight time loops between developing code and the associated unit tests. I'm a big fan of design-by-contract (interfaces first), so I'd like to get a better understanding of how these ideas relate. As a new technical lead at the organizational level, my goal is to bring automated testing into our processes at every level. I see code-level TDD as one piece of that, and I'd like to get ideas for extending those techniques to higher levels. Show

Sometimes thorough, sometimes not. 4 3 3 It's "easy" to do anything. Depending on how the project is lead, it can go wild very easily and the "anything" of above can be changed to "crap".

6 20 C# C, Java, Python, Shell Ceedling (CUnit), NUnit, JUnit, Google test I enjoy being active (hiking, running, golf), (re)learning to play guitar and travelling Currently NUnit and Ceedling (CUnit). Write failing test, write code behind the test, make the test pass, commit, refactor a bit where necessary. (I could use more discipline on the refactoring bit). It's kind of a typical pre-web embedded system comprised of a microcontroller for data acquisition (embedded C) communicating to a single board computer running a Windows C# application via a CAN bus. For the embedded bit, use Atmel studio (now MPLAB X), but found that CLion is a more navigable IDE (refactoring tools inclusive). For the C# side it's Visual Studio with the Resharper plugin (for unit testing and refactoring/autocomplete tools). 31-60 seconds We don't really have a coding standard. Part of this was practicality based as products were accreted from acquisitions - not practical to rewrite large aspects according to coding standard. My efforts are for smaller/testable sprout features When a function seems to do more than one thing, it's too long. When it handles multiple product variants as well as other things, it's too long. We don't currently do any code reviews. At best in Valley Forge, it is one developer per product/product line. Would like to start - emphasis on readability/testability over style. 15 30 55 I like that ideas and pure math are the 'materials' to characterize the world around us, as well as the process of trying to adopt sound (read economical and succinct/correct) engineering practices. It's hard to clean up and 'pay' (via code rework) for messes by quick-fixes made in the past. I try to look at it as more of an opportunity to look for ways to not predict the shape of the code beforehand, but make it easy to work with when needed. I know that Kent Beck wrote a TDD framework for Smalltalk in the mid-90s. The practice makes sense and gives me (and the business) more confidence that something will work, and shortens the time to resolve what bugs do crop up. I've been doing TDD for about 15 years, but I want to make sure I am doing it properly, and learn more techniques (test-wise and design-wise) to build up a catalog of strategies to use for new designs so I don't burden the business with risk/cost.

6 20 C++ Bash C C# GML Java Matlab Custom frameworks Outside of work, I also enjoy writing software. I have recently started experimenting with the game programming. I hold the code written in my personal time to the same high stanadards that I hold the code written at work, and share many techniques and processes between the two. Working in different problem domains gives me new perspectives which can help me solve new problems. When I'm not writing software, I enjoy camping with my family, and snowboarding with my friends. A combination of automated unit tests and manual testing on hardware. Historically, this has skewed mainly towards the latter, but in the last couple of years I have begun to test as much as possible via unit tests. As a project team, we are looking to perform more automated testing on hardware. This is not something I have been involved with personally yet, but am looking forward to learning about it. We typically develop hand held products used for electrical test. These products often involve multiple processors, and need to be designed with safety in mind. Hstorically, IAR tools, but we're moving to GCC and other open source tools that play better integration with CI tools. We develop primarily on Windows, although there is some Linux/WSL work (particularly with CI). We also use Matlab/Simulink. Under 10 seconds We had some vague coding guidelines that were mostly suggestions, and mostly ignored. I developed a coding standard with input from the whole software team. This new standard is followed more closely than the old one. It is overdue for a review. If it's performing multiple distinct tasks it should be split. If it doesn't fit comforatbly in the editor window on a small monitor with other tabs and editor panes open, it should probably be split. We try to review all code that is integrated with the develop branch. There is no formal process for how. Sometimes it is done via screen share, sometimes via Bitbucket pull request.

I have tried to practice this where possible, however, we currently have a lot of legacy code that cannot easily be unit tested. I am trying to refactor this code so that it can be unit tested. The company is looking to adopt Agile processes for software development. TDD is a crucial part of this. I have shown an interest in the subject, so was nominated for the course. Show
