E2E Testing with Playwright

Overview

This directory contains end-to-end (E2E) tests for the authentication system using Playwright. These tests verify the complete user flows in a real browser environment.

Test Coverage

• Login Flow (auth-login.spec.ts)

  • Form validation
  • Invalid credentials handling
  • Successful login
  • Navigation between auth pages
  • Password visibility toggle
  • Loading states

• Registration Flow (auth-register.spec.ts)

  • Form validation (email, first_name, password, confirmPassword)
  • Field-specific validation errors
  • Duplicate email handling
  • Successful registration
  • Navigation and UI interactions

• Password Reset Flow (auth-password-reset.spec.ts)

  • Request reset email validation
  • Success message display
  • Confirm with token validation
  • Missing/invalid token handling
  • Password strength validation
  • Password mismatch validation

• AuthGuard Protection (auth-guard.spec.ts)

  • Route protection
  • Public route access
  • Token persistence
  • Logout behavior
  • Expired token handling
  • Intended destination preservation

Running Tests

# Run all E2E tests
npm run test:e2e

# Run tests in specific browser
npm run test:e2e -- --project=chromium
npm run test:e2e -- --project=firefox
npm run test:e2e -- --project=webkit

# Run tests in headed mode (see browser)
npm run test:e2e -- --headed

# Run specific test file
npm run test:e2e -- auth-login.spec.ts

# Debug mode
npm run test:e2e -- --debug

Current Status

Comprehensive E2E test coverage across all authentication flows. Tests are designed to be non-flaky with proper waits and selectors.

Run npm run test:e2e to verify current status.

Prerequisites

• Dev Server: Must be running on localhost:3000
• Backend API: Should be running on localhost:8000 (optional for some tests)
• Playwright Browsers: Auto-installed via npx playwright install

Configuration

See playwright.config.ts for:

• Browser targets (Chromium, Firefox, WebKit)
• Base URL configuration
• Screenshot and video settings
• Parallel execution settings

Test Structure

Each test file follows this pattern:

test.describe('Feature Name', () => {
  test.beforeEach(async ({ page }) => {
    // Setup before each test
    await page.goto('/route');
  });

  test('should do something', async ({ page }) => {
    // Test implementation
    await expect(page.locator('selector')).toBeVisible();
  });
});

Best Practices

1. Wait for elements - Use await expect().toBeVisible() instead of page.waitForSelector()
2. Unique selectors - Prefer data-testid, role, or specific text over generic CSS
3. Avoid hardcoded delays - Use Playwright's auto-waiting instead of waitForTimeout()
4. Test independence - Each test should be able to run in isolation
5. Clean state - Clear cookies and storage before each test

Debugging

# Run with UI mode
npx playwright test --ui

# Generate trace
npm run test:e2e -- --trace on

# View test report
npx playwright show-report

Future Enhancements

• Add API mocking for consistent test data
• Add visual regression testing
• Add accessibility testing (axe-core)
• Add performance testing
• Integrate with CI/CD pipeline
• Add test data fixtures
• Add page object models for better maintainability
