Testing Instructions

Purpose

Keep tests fast, deterministic, and aligned with core business flows.

Do

• Prioritize core flows first (auth, users CRUD, permission gates).
• Keep assertions user-visible and behavior-focused.
• Reuse existing helper patterns in tests before adding new helpers.
• Keep mock handlers and mock data synchronized with API schemas.
• Prefer focused test runs over full-suite runs during iteration.

Do Not

• Do not add brittle selectors tied to unstable DOM internals.
• Do not expand fixture data without a clear scenario need.
• Do not duplicate scenarios already covered by existing tests.

Validation

• Run focused tests first, then broader checks if needed.
• Run: vp check --no-fmt
