Mandate test-driven development across all platforms. Platform coding standards reference this for the TDD workflow, then add platform-specific test tooling and conventions.
TDD workflow (mandatory)
For any new behavior or bug fix:
Red — Write failing test(s) first
- Derive test cases from acceptance criteria
- Run tests to confirm failure
- Do NOT write implementation code yet
Green — Write minimum code to pass
- No feature creep beyond test requirements
- Run tests after each change
Refactor — Clean up while tests stay green
- Improve code quality without changing behavior
Bug fixes
Bug fixes require a failing test that reproduces the issue before the fix is written.
Completion gate
Stories cannot be marked complete without test files. Test files must exist before marking a story done.
TDD evidence
When implementing features, document in commit or PR:
- Which tests were written first
- Confirmation that tests failed before implementation
