Coverage Until Threshold
Add focused tests until coverage meets your threshold (e.g. 80%), without changing production behavior unnecessarily.
Kickoff prompt
Start the "Coverage Until Threshold" loop.
Goal: coverage meets the target threshold (default 80%) with all tests passing
Max iterations: 12
Between iterations run: npm test -- --coverage
Exit when: coverage threshold is met and tests exit 0
Step 1: Run coverage. Add focused tests for the biggest uncovered gaps, then repeat.
Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.Basic information

Steps
- 1
Measure coverage
Run tests with coverage reporting enabled.
npm test -- --coverage - 2
Add tests
Write the smallest tests needed to cover uncovered branches. No snapshot spam or trivial asserts.
- 3
Re-measure
Re-run coverage and confirm threshold is met.
npm test -- --coverage
More Testing loops
Build Until Green
Run the production build, fix compile and bundling errors, and loop until the build succeeds.
Pre-Commit Guard
Hook that runs tests before git commit commands to block commits when the suite is red.
Post-Edit Test Guard
Hook-based loop that runs related tests after file edits to catch regressions early.
Format Until Clean
Run the formatter, fix any remaining style issues, and loop until the codebase formats cleanly with no diffs.
Flaky Test Triage
Run failing tests repeatedly, classify each failure as flaky or real, and fix only confirmed regressions.
Autoloop TDD
Test-first loop: write a failing test, implement the minimum code to pass, refactor, and repeat.
