Guidelines for testing the application with Vitest, including unit tests, integration tests (emulator), AI tests, and eval suites for LLM features

Tokens, turns and time describe resource use, not a dollar price.
One of 16 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need to read about how our project handles LLM-as-judge evaluation and cross-model comparison testing. Which document file should I open?
| Checked | Without skill | With skill |
|---|---|---|
| Points to eval.md as the file covering cross-model comparisons and LLM-as-judge. | Missed | Passed |
The instructions your model reads when the skill loads.
All testing guidance lives in this directory. Read the relevant file for your task:
| Type | File | When to use |
|---|---|---|
| Unit tests | unit.md | Framework setup, mocks, colocated tests |
| Writing tests | write-tests.md | What to test, what to skip, workflow |
| LLM tests | llm.md | Tests that call real LLMs (pnpm test-ai) |
| Eval suite | eval.md | Cross-model comparison, LLM-as-judge |
| Integration | integration.md | Emulator-backed tests (pnpm test-integration) |
| Database | apps/web/__tests__/db/README.md | Real Postgres, for unique constraints and updateMany count guards (pnpm test-db) |
| E2E tests | e2e.md | Real email workflow tests from inbox-zero-e2e repo |
Prefer behavior-focused assertions; avoid freezing prompt copy or internal call shapes unless those exact values are the contract under test.
