Testing

pytest Layout (Backend)

• Application-specific tests live inside their respective apps (e.g., users/tests/, pipeline/tests/).
• The top-level tests/ directory is reserved strictly for full-system integration tests.
• Ensure you are running under the host-side track (SQLite memory:) for speed. Example: just backend-test.

Vitest Layout (Frontend)

• Tests live immediately beside the files they test (e.g., index.test.tsx).
• We do not use separate __tests__/ folders.

Storybook Usage

• UI components in elements/ and layout/ should have .stories.tsx files demonstrating their permutations.

Coverage Expectations

Use the .github/skills/coverage-auditor/SKILL.md to spot gaps. All new logic branches in APIs, serializers, and utility functions should be covered.

When to Use just Test Targets

• just test: Runs all backend AND frontend tests.
• just backend-test: Only runs pytest.
• just frontend-test: Only runs vitest.
