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:
bun run test
If tests fail, fix them first.
After implementing:
bun 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
bun run test # All tests (unit + db)
bun run test:unit # Frontend only
bun run test:db # Database only (pgTAP)
If Tests Fail
Read the error message
Check if YOUR change caused it
If yes → fix your code
If no → fix the test or report the issue
