Refactoring and SOLID Design for C Training

This training course helps you build knowledge, understanding and skill in the engineering practices needed to build great C code. You learn how to build flexible and modular software with very few defects, software that can have a long useful life. We teach you how to prevent defects and how to keep code clean over years of evolving needs.

Learning Model

We learn new skills by doing, not just reading, listening, and thinking. Engineers are not so interested in changing how they work if the change does not help solve some identified problem. We’ve found this learning cycle to be invaluable from attendees of our courses.

  • Present a problem -- problems motivate change
  • Present a potential solution -- the idea that may help
  • Demonstrate part of the solution -- remove ambiguity
  • Participant does an exercise -- learn by doing
  • Experience debrief -- identify and discuss both positive and negative reactions

In this course, we repeat this learning cycle growing skills with each iteration. The goal is to build new skills on top of the attendees' existing skills.

Audience

  • Software Developers
  • Technical team leaders
  • Managers that want to know more about the technology they manage

Prerequisites

  • Completed one of our Test-Driven Development training courses
  • C programming experience

Course Outline

  • Refactoring

    • Module Objective: As requirements and users' needs change, code must change. Design is so important, we don't just do design once at the beginning of the development effort. Design is a continuous process. We accept that changing design is dangerous, and the tests created by the test-driven developer provide a safety-net to lock in code behavior as your product design evolves.

    Refactoring (changing the structure of code, without changing its behavior) is a step in the TDD microcycle used when we need to clean up a mess. We'll also refactor code so that a new feature can be dropped in. This module provides and overview of the mindset and the critical skills needed to evolve designs for a long useful life.

  • SOLID Design

    Module Objective: There are many guiding principles to help with design. Knowing these principles helps you test-drive or refactor your problem design to a better design. This module helps you understand some of the guiding principles that help transform design decisions from personal preferences to specific design decisions based on specific attributes and tradeoffs.
