Test Driven Development

@romiluz13/cc10x-cc10x-test-driven-development

Enforces TDD with functionality-first, context-dependent approach. Use PROACTIVELY when building features. First understands functionality requirements using universal questions and context-dependent flows, then writes tests verifying that functionality, then implements code to make tests pass. Understands project test patterns and conventions. Focuses on tests that verify functionality works, not generic test coverage. Enforces the RED -> GREEN -> REFACTOR loop with mandatory command execution and verification. Provides specific test examples.
