Test-Driven Development

Description

TDD methodology for development phase. Focus on testing what you build.

Details

Core principle: Write tests for the code you write.

Follow Red/Green/Verify cycle:

1. Red: Write a failing test first

• Write the test code that calls the new function
• Add function declaration to header file
• Add stub implementation that compiles but does nothing (e.g., return OK(NULL);)
• A compilation error is NOT a failing test - you need a stub that compiles and runs
• Verify the test actually fails with assertion failures
