name: testing description: >- Run tests before and after changes. Only add tests for complex logic, not boilerplate. Database tests matter most.

Testing

Verify changes don't break things. Don't create test bloat.

Announce: "I'm running tests to verify the changes."

Philosophy

Database (pgTAP): This is where real logic lives. Test it thoroughly.

Frontend (Vitest): Thin RPC layer. Only test:

• Complex transformations
• Non-obvious edge cases
• NOT: "does this call that function"

Workflow

Before implementing:

Copybun run test

If tests fail, fix them first.

After implementing:

Copybun run test

If tests fail, your change broke something. Fix it.

When to Add Tests

YES - add tests for:

• New database functions with business logic
• Complex data transformations
• Non-obvious edge cases you discovered

NO - don't test:

• "Does this function call that function"
• Pinia store initialization
• Vue component mounting
• API calls with mocked responses
• Obvious behavior readable from code

Commands

Copybun run test        # All tests (unit + db)
bun run test:unit   # Frontend only
bun run test:db     # Database only (pgTAP)

If Tests Fail

1. Read the error message
2. Check if YOUR change caused it
3. If yes → fix your code
4. If no → fix the test or report the issue
