Testing
Playwright E2E, billing and isolation tests. Ship with confidence. Regression safety and refactor confidence.
What this system covers
E2E with Playwright
End-to-end tests for critical flows in a real browser. Playwright is CI-friendly and fast. We cover auth, navigation, and key user journeys so regressions get caught before release.
Billing tests
Checkout, webhooks, and billing state transitions are tested. You can assert on subscription states, webhook handling, and idempotency so revenue paths stay reliable.
Tenant isolation tests
Tests verify that one tenant never sees another's data. API and UI isolation are asserted so multi-tenancy stays safe as you refactor.
Mocking and verification
External services (payments, email, storage) can be mocked. We document patterns for idempotency and verification so tests stay fast and deterministic.
Why tests are in the kit
Regression safety and refactor confidence. E2E and billing tests catch breakage before users do. Isolation tests protect multi-tenancy. We include a baseline so you can extend coverage and run tests in CI from day one.
Decisions & trade-offs
We include Playwright E2E tests and billing/isolation coverage so you don't ship without a safety net. The goal is regression safety and refactor confidence: critical paths (auth, billing, tenant isolation) are tested so you can iterate without fear. We document mocking and CI so you can extend coverage as the product grows.
Pros
- Playwright runs in real browsers and is CI-friendly; one runner for E2E.
- Billing and isolation tests protect revenue and multi-tenancy from day one.
- Baseline tests document expected behavior; new contributors can extend.
- Mocking patterns for payments and external services keep tests fast and deterministic.
Trade-offs
- E2E tests are slower than unit tests; we focus on critical paths, not full coverage.
- Flakiness can occur; we document best practices (wait strategies, idempotency) to reduce it.
- Visual or accessibility testing is not included by default; you can add with Playwright.
