Analyzing E2e Tests

Analyzing E2E Tests

Output: docs/unwind/layers/e2e-tests/ (folder with index.md + section files)

Principles: See analysis-principles.md - completeness, machine-readable, link to source, no commentary, incremental writes.

Output Structure

docs/unwind/layers/e2e-tests/
├── index.md           # Test summary, browser matrix
├── config.md          # Playwright/Cypress config, CI setup
├── page-objects.md    # Page object definitions
├── fixtures.md        # Test data and fixtures
└── flows.md           # User flow tests

For large codebases, split by feature:

Process (Incremental Writes)

Step 1: Setup

mkdir -p docs/unwind/layers/e2e-tests/

Write initial index.md:

# E2E Tests

## Sections
- [Configuration](config.md) - _pending_
- [Page Objects](page-objects.md) - _pending_
- [Test Fixtures](fixtures.md) - _pending_
- [User Flows](flows.md) - _pending_

## Summary
_Analysis in progress..._

Step 2: Analyze and write config.md

1. Find Playwright/Cypress config, CI setup
2. Write config.md immediately
3. Update index.md

Step 3: Analyze and write page-objects.md

1. Find all page object definitions
2. Write page-objects.md immediately
3. Update index.md

Step 4: Analyze and write fixtures.md

1. Find test data and fixtures
2. Write fixtures.md immediately
3. Update index.md

Step 5: Analyze and write flows.md

1. Find all user flow tests
2. Write flows.md immediately
3. Update index.md

Step 6: Finalize index.md Add test summary and browser matrix

## Configuration

### Playwright Config

[playwright.config.ts](https://github.com/owner/repo/blob/main/playwright.config.ts)

```typescript
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  testDir: './e2e',
  fullyParallel: true,
  retries: process.env.CI ? 2 : 0,
  workers: process.env.CI ? 1 : undefined,
  reporter: 'html',
  use: {
    baseURL: 'http://localhost:3000',
    trace: 'on-first-retry',
  },
  projects: [
    { name: 'chromium', use: { ...devices['Desktop Chrome'] } },
    { name: 'firefox', use: { ...devices['Desktop Firefox'] } },
    { name: 'webkit', use: { ...devices['Desktop Safari'] } },
  ],
  webServer: {
    command: 'npm run dev',
    url: 'http://localhost:3000',
    reuseExistingServer: !process.env.CI,
  },
});

Test Summary

Page Objects

LoginPage

LoginPage.ts

export class LoginPage {
  constructor(private page: Page) {}

  async goto() {
    await this.page.goto('/login');
  }

  async login(email: string, password: string) {
    await this.page.fill('[data-testid="email"]', email);
    await this.page.fill('[data-testid="password"]', password);
    await this.page.click('[data-testid="submit"]');
  }

  async getErrorMessage() {
    return this.page.textContent('[data-testid="error"]');
  }
}

Authentication Tests

auth.spec.ts

auth.spec.ts

import { test, expect } from '@playwright/test';
import { LoginPage } from './pages/LoginPage';

test.describe('Authentication', () => {
  test('successful login redirects to dashboard', async ({ page }) => {
    const loginPage = new LoginPage(page);
    await loginPage.goto();
    await loginPage.login('user@example.com', 'password123');

    await expect(page).toHaveURL('/dashboard');
    await expect(page.locator('[data-testid="welcome"]')).toBeVisible();
  });

  test('invalid credentials shows error', async ({ page }) => {
    const loginPage = new LoginPage(page);
    await loginPage.goto();
    await loginPage.login('user@example.com', 'wrongpassword');

    await expect(page.locator('[data-testid="error"]')).toHaveText('Invalid credentials');
  });

  test('logout clears session', async ({ page }) => {
    // Login first
    const loginPage = new LoginPage(page);
    await loginPage.goto();
    await loginPage.login('user@example.com', 'password123');

    // Logout
    await page.click('[data-testid="logout"]');

    await expect(page).toHaveURL('/login');
  });
});

Order Flow Tests

order.spec.ts

test.describe('Order Flow', () => {
  test.beforeEach(async ({ page }) => {
    // Login before each test
    await page.goto('/login');
    await page.fill('[data-testid="email"]', 'user@example.com');
    await page.fill('[data-testid="password"]', 'password123');
    await page.click('[data-testid="submit"]');
  });

  test('complete order flow', async ({ page }) => {
    // Add product to cart
    await page.goto('/products');
    await page.click('[data-testid="product-1"] [data-testid="add-to-cart"]');

    // Go to cart
    await page.click('[data-testid="cart-icon"]');
    await expect(page.locator('[data-testid="cart-item"]')).toHaveCount(1);
