#023 - Modernization Embedded Systems with Test-Driven Development
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Key Takeaways:
• Test-driven development requires writing tests first, then production code to make tests pass, which feels counterintuitive initially but improves over time
• Properly architected embedded software with decoupled hardware layers makes TDD highly effective for application code
• The mental adjustment to TDD takes several weeks but results in faster overall development and higher code quality
• TDD provides immediate feedback when changes break existing functionality through regression testing
• Multiple testing types are available: unit, integration, system, regression, performance, and user acceptance testing
• System-level TDD can drive development from user requirements down to individual components
• AI tools can accelerate TDD processes while maintaining rigorous testing standards
• A simple push button module can require 98 tests and 4,000 checks for complete validation
• 100% test coverage is a worthy goal but doesn't guarantee bug-free code
• TDD initially feels slower but dramatically reduces debugging time and improves long-term development velocity
