In the world of software engineering, robust and efficient testing is crucial for ensuring reliable software. But what happens when your code interacts with hardware?
This session provides a step-by-step walkthrough of mocking UART interfaces in C++. Through a practical, demo-driven approach, we’ll explore how to decouple your code from hardware dependencies, simulate UART behavior, and build effective unit tests, even at compile time.
Best of all, we’ll achieve this without relying on any testing frameworks, just plain C++. By the end of this talk, you’ll have a clear understanding of how to integrate mocking techniques into your development workflow, enabling more reliable and maintainable embedded software.
