E2E Test Plan E2E Test Plan Project: {{PROJECT_NAME}} Version: {{VERSION}} Date: {{DATE}} Author: {{AUTHOR}} Status: Draft | In Review | Approved Reviewers: {{REVIEWERS}} Document History Version Date Author Changes 0.1 {{DATE}} {{AUTHOR}} Initial draft 1. E2E Testing Objectives Objectives: Validate that the {{COUNT}} most critical user journeys work end-to-end in a production-like environment Catch integration failures between frontend, backend, and third-party services that unit/integration tests cannot detect Provide confidence before every production deployment Serve as living documentation of critical user flows What E2E tests are NOT for: Complete feature coverage (that's for unit/integration tests) Testing every error state (too expensive to maintain) Performance benchmarking (use performance tests) Visual pixel-perfection (use visual regression tests separately) 2.

Test Data Setup & Teardown Setup Strategy Data Type Method Scope Test user accounts Pre-seeded before test run Test suite {{DATA_TYPE}} Created via API in beforeAll Test suite Isolated test data Created via API in beforeEach Individual test Seed command: bash scripts/e2e-seed.sh {{ENVIRONMENT}} Seed verification: bash scripts/verify-seed.sh {{ENVIRONMENT}} Teardown Strategy Cleanup Item Method Trigger Test-specific records DELETE via API afterEach Test session data Clear browser storage afterEach Emails in test inbox API clear afterAll Payment test data Stripe test mode auto-cleanup Daily job Rule: Tests must not leave state that affects other tests. Tests must be executable in any order. Test Accounts Account Email Role Purpose Standard user e2e-user@test.{{DOMAIN}} User Standard journeys Admin user e2e-admin@test.{{DOMAIN}} Admin Admin panel journeys {{ROLE}} user e2e-{{ROLE}}@test.{{DOMAIN}} {{ROLE}} {{PURPOSE}} Credentials stored in: {{CREDENTIAL_STORE}} (never hardcoded in tests) 5. Authentication Handling in Tests Strategy: {{AUTH_STRATEGY}} Recommended approach (Playwright): // tests/fixtures/auth.ts // Authenticate via API, save storage state // Reuse state across tests in the same suite // Only use UI login when testing the login flow itself Session reuse: Session state saved per role after first auth Reused for all tests requiring that role Invalidated and refreshed if expired 6. Test Environment Requirements Requirement Specification Environment Staging ( staging.{{DOMAIN}} ) Database Dedicated E2E database, seeded before run External services Sandbox / test mode (Stripe test, email sandbox) Stability No active deployments during E2E run Data persistence Isolated — not shared with manual testing Response times < {{TIMEOUT}}s for all endpoints (E2E assertions time out at 2× this) Environment locking: CI acquires a lock before E2E run to prevent concurrent deployments Lock mechanism: {{LOCK_MECHANISM}} 7. Flaky Test Management Strategy Definition: A test that fails inconsistently for the same code Prevention: Use explicit waits (not sleep ) — wait for elements/network, not time Isolate test data (no shared state between tests) Use retry-on-assertion, not retry-on-run Avoid animation timing issues with prefers-reduced-motion in test env Detection: Track flakiness rate per test in CI Any test failing > {{FLAKY_THRESHOLD}}% of runs without code changes = flaky Response: Immediately tag flaky test with @flaky annotation Create bug ticket with priority based on journey criticality Quarantine (run separately, don't block CI) while fixing Fix within {{FLAKY_FIX_SLA}} days or remove the test Monthly flaky test review 8. Visual Regression Testing Tool: {{VIS_TOOL}} Baseline: Stored in {{BASELINE_STORAGE}} Threshold: Allow up to {{VIS_THRESHOLD}}% pixel difference for font rendering Check Scope Trigger Full page screenshots Critical pages UI-touching PRs Component snapshots UI components Component changes Responsive layout Mobile + desktop Layout changes Review process: Visual diffs in PR requiring explicit approval before merge 9. Performance Assertions Within E2E Assertion Metric Threshold Journey Page load Time to Interactive < {{TTI}}ms All critical pages Core Web Vitals — LCP Largest Contentful Paint < {{LCP}}ms Homepage, landing pages Core Web Vitals — CLS Cumulative Layout Shift < {{CLS}} All pages API response Time in test assertions < {{API_TIMEOUT}}ms All API calls 10. CI Integration Trigger: Post-staging deployment Parallelization: Test sharding: {{SHARD_COUNT}} shards Browser parallelism: {{BROWSER_WORKERS}} workers per shard Estimated total time: {{E2E_TOTAL_TIME}} minutes CI configuration: # Reference: {{CI_CONFIG_PATH}} # Key settings: # - Shards: {{SHARD_COUNT}} # - Retries: {{RETRY_COUNT}} (for non-flaky tests only) # - Timeout per test: {{TEST_TIMEOUT}}ms # - Timeout total: {{SUITE_TIMEOUT}}min On failure: Collect screenshots, videos, traces as artifacts Retain artifacts for {{ARTIFACT_RETENTION}} days Alert Slack channel #e2e-failures 11. Test Report Format & Artifacts Report format: {{REPORT_FORMAT}} Report location: {{REPORT_URL}} or CI artifacts Artifacts collected on failure: Artifact Format When Collected Screenshot PNG On step failure Screen recording WebM video On test failure Network trace HAR file On test failure Browser console log JSON On test failure Playwright trace .zip (trace viewer) On test failure 12. Maintenance Strategy Page Object Pattern: All page interactions wrapped in Page Object classes Selectors centralized — change in one place Location: tests/e2e/pages/ Selector strategy: data-testid attributes (preferred — stable, intent-clear) ARIA roles + accessible name (good for accessibility alignment) Text content (acceptable for static text) CSS class names (avoid — coupled to styling) XPath (never — fragile) Review cadence: Test suite reviewed monthly for relevance Remove tests for deprecated features immediately Update tests before merging feature changes (tests are part of the PR) Related Documents Test Strategy Test Plan Test Case Template CI/CD Pipeline Approval Role Name Date Signature Author Reviewer Approver
