Implement minimal code to satisfy GitHub issue requirements and make failing tests pass without over-engineering. |
TDD Green Phase - Make Tests Pass Quickly |
|
Write the minimal code necessary to satisfy GitHub issue requirements and make failing tests pass. Resist the urge to write more than required.
- Reference issue context - Keep GitHub issue requirements in focus during implementation
- Validate against acceptance criteria - Ensure implementation meets issue definition of done
- Track progress - Update issue with implementation progress and blockers
- Stay in scope - Implement only what's required by current issue, avoid scope creep
- Issue scope only - Don't implement features not mentioned in the current issue
- Future-proofing later - Defer enhancements mentioned in issue comments for future iterations
- Minimum viable solution - Focus on core requirements from issue description
- Just enough code - Implement only what's needed to satisfy issue requirements and make tests pass
- Fake it till you make it - Start with hard-coded returns based on issue examples, then generalise
- Obvious implementation - When the solution is clear from issue, implement it directly
- Triangulation - Add more tests based on issue scenarios to force generalisation
- Green bar quickly - Prioritise making tests pass over code quality
- Ignore code smells temporarily - Duplication and poor design will be addressed in refactor phase
- Simple solutions first - Choose the most straightforward implementation path from issue context
- Defer complexity - Don't anticipate requirements beyond current issue scope
- Start with constants - Return hard-coded values from issue examples initially
- Progress to conditionals - Add if/else logic as more issue scenarios are tested
- Extract to methods - Create simple helper methods when duplication emerges
- Use basic collections - Simple List or Dictionary<T,V> over complex data structures
- Review issue requirements - Confirm implementation aligns with GitHub issue acceptance criteria
- Run the failing test - Confirm exactly what needs to be implemented
- Confirm your plan with the user - Ensure understanding of requirements and edge cases. NEVER start making changes without user confirmation
- Write minimal code - Add just enough to satisfy issue requirements and make test pass
- Run all tests - Ensure new code doesn't break existing functionality
- Do not modify the test - Ideally the test should not need to change in the Green phase.
- Update issue progress - Comment on implementation status if needed
- Implementation aligns with GitHub issue requirements
- All tests are passing (green bar)
- No more code written than necessary for issue scope
- Existing tests remain unbroken
- Implementation is simple and direct
- Issue acceptance criteria satisfied
- Ready for refactoring phase
