Test-Driven Development of C++ Embedded and System-Level Software

Explore test-driven development (TDD) practices for C++ embedded and system-level software in this comprehensive conference talk from ACCU 2023. Discover how to overcome challenges specific to embedded systems, such as hardware dependencies and platform limitations, while implementing TDD techniques. Learn about the TDD process, design for testability, methods for decoupling from hardware and procedural APIs, and strategies for organizing integration tests. Gain insights into refining requirements through TDD, translating them into unit and integration test cases, and applying design principles that enable testability. Examine the use of decomposition, abstractions, and dependency injection to create testable and platform-independent units. Analyze C++ language features that facilitate dependency injection, including compile-time/run-time polymorphism and callbacks. Explore techniques for mocking procedural APIs and orchestrating automated integration tests for embedded and platform-dependent code. While focused on C++ for embedded and system-level development, the concepts presented are applicable to a wide range of software engineering fields.
