Testing Strategy

Testing Pyramid​

  • Unit tests: utility, formatter, mapper, validation.
  • Integration tests: API client + data adapter + error mapping.
  • E2E tests: critical user flow (happy path + failure path).

Baseline Rules​

  • Every bug fix must include a regression test.
  • Hindari over-mocking di integration test.
  • E2E focuses on high-risk flows, not every page.

Suggested Tooling​

  • Unit/Integration: Vitest/Jest.
  • E2E: Playwright.
  • Initial coverage gate target: 70% for critical modules.
