Testing Frameworks

Web Testing Frameworks

Selenium

Best for: Cross-browser testing, legacy applications

• Supports multiple languages (Java, Python, JavaScript, C#)
• Wide browser support including legacy browsers
• Large community and extensive documentation
• Steeper learning curve
• Slower execution compared to modern frameworks

// Java Selenium example
WebDriver driver = new ChromeDriver();
driver.get("https://example.com");
WebElement element = driver.findElement(By.id("username"));
element.sendKeys("testuser");
driver.quit();

Cypress

Best for: Modern web applications, fast feedback

• JavaScript/TypeScript native
• Real-time reloads and debugging
• Automatic waiting and retries
• Network traffic control and stubbing
• Excellent developer experience
• Limited to JavaScript-based applications

// Cypress example
describe('Login', () => {
  it('should login successfully', () => {
    cy.visit('/login');
    cy.get('#username').type('testuser');
    cy.get('#password').type('password');
    cy.get('#login').click();
    cy.url().should('include', '/dashboard');
  });
});

Playwright

Best for: Modern web applications, cross-browser testing

• Multi-language support (JavaScript, Python, Java, .NET)
• Fast, reliable, and cross-browser
• Auto-waiting for elements
• Network interception and mocking
• Parallel test execution
• Headless and headed execution

// Playwright JavaScript example
const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.fill('#username', 'testuser');
  await page.click('#login');
  await browser.close();
})();

Puppeteer

Best for: Chrome/Chromium testing, scraping

• Chrome DevTools Protocol integration
• Headless browser automation
• Fast execution
• JavaScript/TypeScript native
• Chrome/Chromium only

// Puppeteer example
const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.type('#username', 'testuser');
  await page.click('#login');
  await browser.close();
})();
