Agent Skills: Fix Failing Tests

Fix Failing Tests

Use this when you have failing test output. The goal is to fix ALL failing tests, re-run tests, and iterate until everything passes.

Usage

/fix-tests

Use this after you've pasted test failure output into the conversation.

What It Does

1. Understands ALL Failures

   • Reads entire test log (pytest / Jest / parallel tests)
   • Checks "Test Results" summary for ALL failing tests (looks for ✗ or FAILED markers)
   • Checks "Failed Test Details" for MULTIPLE failing test groups
   • Notes ALL test groups that failed (backend, frontend, linting, etc.)
   • Creates list of all failures before starting fixes

2. Fixes EACH Failure

   • For EACH failing service/group:
     • Opens failing test files and implementation files
     • Makes smallest, clearest change
     • Prefers fixing implementation over changing tests
   • Fixes ALL failures before proceeding

3. Re-runs Tests for EACH Fix

   • Backend: pytest (or with -k for specific tests)
   • Frontend: npm run lint or npm run test
   • Verifies each group passes before moving to next
   • Repeats if tests still fail

4. Re-runs Full Test Suite

   • CRITICAL: Always re-runs original command used to run tests
   • Catches hidden failures or new failures from fixes
   • Only stops when full suite passes with zero failures

Important Notes

• Don't stop after fixing one failure - check for multiple failing groups
• Always re-run full test suite after fixes
• Parse entire error output - summary AND detailed sections

Testing Commands

Backend (pytest):

pytest                              # All unit tests
pytest -k "pattern"                 # Specific tests
pytest tests/integration/           # Integration tests

Frontend:

npm run lint
npm run test
