# E2E Testing Patterns

Playwright E2E testing patterns — Page Object Model, configuration, CI/CD integration, artifact management, flaky test strategies, PLUS the decision-time patterns that come before the first test is written (black-box helper scripts, static-vs-dynamic routing, multi-server orchestration, reconnaissance-then-action, application-state readiness assertions).

## Working procedure

1. Establish the relevant mode and existing evidence; do not repeat completed intake.
2. Choose critical observable user journeys and test against an authorized isolated environment. Use locator actions and web-first assertions; avoid fixed sleeps and blanket network-idle waits. Keep secrets out of artifacts. Browser rendering, hydration and accessibility checks may be needed even for static HTML.
3. Read only the corresponding sections below before applying their examples.
4. Verify the result with meaningful positive, negative and failure controls. Record actual outcomes, limitations and next action.
