litestar-testing

Litestar-specific testing patterns built on pytest + anyio. Covers:

• TestClient vs AsyncTestClient — when to use each
• @pytest.mark.anyio setup
• App + lifespan in tests
• Fixture patterns from canonical litestar-fullstack tests
• Mocking Guards and DI dependencies
• Integration with pytest-databases (see ../pytest-databases/SKILL.md)
• Request body / form / multipart / header / cookie testing
• Litestar-specific assertion patterns (Response, headers, cookies)

For JS-side testing (Vitest, Testing Library, Playwright), use the upstream Vitest docs and Litestar's own JS examples. Out of scope here.
