disable-model-invocation: true
allowed-tools: Bash, Write, Read, Glob, Grep

Purpose

Create, run, and maintain E2E tests for critical user flows using Playwright.

Arguments

  • •--add <journey> — Create new journey test (e.g., signup-flow, checkout)
  • •--run — Run all E2E tests
  • •--run <pattern> — Run tests matching pattern
  • •--report — Generate and display HTML report
  • •--fix — Fix flaky tests with approval

Test organization

code
apps/web/e2e/
├── journeys/              # User journey tests
│   ├── auth.spec.ts       # Sign up, sign in, sign out
│   ├── onboarding.spec.ts # First-time user flow
│   └── <feature>.spec.ts  # Feature-specific journeys
├── fixtures/              # Test fixtures and helpers
│   ├── auth.ts            # Auth helpers (login as user)
│   └── db.ts              # Database seeding
├── pages/                 # Page Object Models
│   ├── HomePage.ts
│   └── SettingsPage.ts
└── playwright.config.ts   # Playwright configuration

Journey naming

  • •auth — Authentication flows (signup, signin, signout, password reset)
  • •onboarding — First-time user experience
  • •<feature>-crud — Create, read, update, delete for a feature
  • •<feature>-workflow — Multi-step workflows
  • •checkout — Payment/purchase flows
  • •settings — User settings and preferences

Commands

bash
# Run all E2E tests
pnpm test:e2e

# Run specific journey
pnpm test:e2e --grep "auth"

# Run in headed mode (watch)
pnpm test:e2e --headed

# Run with UI mode
pnpm test:e2e --ui

# Generate report
pnpm test:e2e --reporter=html && npx playwright show-report

Workflow

Adding a journey (--add)

  1. •Create test file in e2e/journeys/<journey>.spec.ts
  2. •Create page objects if needed
  3. •Add fixtures for test data
  4. •Run to verify
  5. •Add to CI if not already included

Running tests (--run)

  1. •Ensure dev server is running or use webServer config
  2. •Execute tests
  3. •Report results with pass/fail counts
  4. •Highlight flaky tests (passed on retry)

Fixing flaky tests (--fix)

  1. •Identify flaky tests from reports
  2. •Analyze failure patterns
  3. •Propose fixes (with approval):
    • •Add explicit waits
    • •Improve selectors
    • •Fix race conditions
    • •Mock unstable dependencies
  4. •Re-run to confirm fix

Best practices enforced

  • •Use data-testid for stable selectors
  • •Avoid time-based waits (page.waitForTimeout)
  • •Isolate tests (no shared state)
  • •Reset database state between tests
  • •Use page object models for reusability

Output

  • •Test results (pass/fail/flaky counts)
  • •Failure details with screenshots
  • •Report location
