| Generate end-to-end browser tests for user workflows | e2e |
End-to-End Test Generator
Generate comprehensive browser-based E2E tests for complete user workflows using Playwright, Cypress, or Selenium.
Purpose
Create automated tests that simulate real user interactions:
- Complete user journeys (signup → login → purchase)
- Multi-page workflows
- Form interactions and validations
- Navigation flows
- Browser-specific behaviors
- Mobile responsive testing
Supported Frameworks
Playwright (Recommended)
- Multi-browser support (Chromium, Firefox, WebKit)
- Auto-wait for elements
- Network interception
- Mobile emulation
- Parallel execution
Cypress
- Time-travel debugging
- Real-time reloads
- Automatic waiting
- Network stubbing
- Screenshot/video capture
Selenium WebDriver
- Mature ecosystem
- Cross-browser support
- Remote execution (Selenium Grid)
- Mobile testing (Appium)
Test Generation
When invoked, generate E2E tests with:
-
User workflow analysis
- Identify key user journeys
- Map page interactions
- Define success criteria
-
Page Object Model
- Create page classes
- Define selectors
- Implement action methods
-
Test scenarios
- Happy path workflows
- Error handling paths
- Edge cases
-
Assertions
- URL validation
- Element presence
- Content verification
- State changes
Example: Playwright Test
import { test, expect } from '@playwright/test';
test.describe('User Registration Flow', () => {
test('should complete full registration workflow', async ({ page }) => {
// Navigate to signup
await page.goto('https://example.com/signup');
// Fill registration form
await page.fill('[name="email"]', '[email protected]');
await page.fill('[name="password"]', 'SecurePass123!');
await page.fill('[name="confirmPassword"]', 'SecurePass123!');
await page.check('[name="terms"]');
// Submit and wait for navigation
await page.click('button[type="submit"]');
await page.waitForURL('**/verify-email');
// Verify success message
await expect(page.locator('.success-message')).toContainText(
'Please check your email'
);
});
test('should show validation errors for invalid data', async ({ page }) => {
await page.goto('https://example.com/signup');
// Submit empty form
await page.click('button[type="submit"]');
// Verify error messages
await expect(page.locator('.error-email')).toBeVisible();
await expect(page.locator('.error-password')).toBeVisible();
});
});
test.describe('E-commerce Purchase Flow', () => {
test.beforeEach(async ({ page }) => {
// Login before each test
await page.goto('https://example.com/login');
await page.fill('[name="email"]', '[email protected]');
await page.fill('[name="password"]', 'password123');
await page.click('button[type="submit"]');
await page.waitForURL('**/dashboard');
});
test('should complete product purchase', async ({ page }) => {
// Browse products
await page.goto('https://example.com/products');
await page.click('text=Add to Cart').first();
// Verify cart badge
await expect(page.locator('.cart-badge')).toHaveText('1');
// Go to checkout
await page.click('.cart-icon');
await page.click('text=Checkout');
// Fill shipping info
await page.fill('[name="address"]', '123 Main St');
await page.fill('[name="city"]', 'San Francisco');
await page.fill('[name="zip"]', '94102');
await page.click('text=Continue');
// Enter payment (test mode)
await page.fill('[name="cardNumber"]', '4242424242424242');
await page.fill('[name="expiry"]', '12/25');
await page.fill('[name="cvc"]', '123');
await page.click('text=Place Order');
// Verify success
await page.waitForURL('**/order/confirmation');
await expect(page.locator('.order-success')).toBeVisible();
await expect(page.locator('.order-number')).toContainText('ORDER-');
});
});
Example: Cypress Test
describe('User Dashboard Workflow', () => {
beforeEach(() => {
cy.login('[email protected]', 'password123');
});
it('should load dashboard with user data', () => {
cy.visit('/dashboard');
cy.get('.welcome-message').should('contain', 'Welcome, John');
cy.get('.user-stats').should('be.visible');
});
it('should create new project', () => {
cy.visit('/dashboard');
cy.get('[data-testid="new-project"]').click();
cy.get('[name="projectName"]').type('My New Project');
cy.get('[name="description"]').type('Project description here');
cy.get('button[type="submit"]').click();
cy.url().should('include', '/projects/');
cy.get('.project-title').should('contain', 'My New Project');
});
});
Page Object Model
// pages/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('[name="email"]', email);
await this.page.fill('[name="password"]', password);
await this.page.click('button[type="submit"]');
}
async getErrorMessage() {
return this.page.locator('.error-message').textContent();
}
}
// Test using Page Object
test('login with page object', async ({ page }) => {
const loginPage = new LoginPage(page);
await loginPage.goto();
await loginPage.login('[email protected]', 'password123');
await expect(page).toHaveURL('/dashboard');
});
Best Practices
- Use data-testid attributes - Stable selectors
- Implement Page Objects - Reusable page interactions
- Handle waits properly - Auto-wait or explicit waits
- Test realistic scenarios - Actual user workflows
- Parallelize tests - Faster execution
- Capture screenshots on failure - Debugging aid
- Use fixtures - Consistent test data
- Test across browsers - Chrome, Firefox, Safari
