Page Object Model in Playwright

 The Page Object Model (POM) is a widely used design pattern in test automation that promotes maintainability, readability, and reusability of test scripts. When combined with Playwright, a modern end-to-end testing framework, POM becomes a powerful strategy to manage complex test scenarios effectively.

What Is Page Object Model?

In POM, each web page in your application is represented by a class, and all the elements and interactions related to that page are defined as methods within that class. This separation of concerns helps testers keep test logic clean and organized.

For example, a LoginPage class might include locators for the username and password fields, and a method like login(username, password) to perform the login action.

Why Use POM with Playwright?

Playwright offers fast, reliable automation across modern browsers (Chrome, Firefox, Safari). By combining it with the Page Object Model, you can:

  • Avoid code duplication
  • Improve test readability
  • Simplify maintenance

Enhance scalability as your project grows

Creating a POM in Playwright

Here’s a simple example using JavaScript/TypeScript with Playwright:

1. LoginPage.ts

import { Page } from '@playwright/test';

export class LoginPage {

  readonly page: Page;

  readonly usernameInput = '#username';

  readonly passwordInput = '#password';

  readonly loginButton = '#login';

  constructor(page: Page) {

    this.page = page;

  }

  async login(username: string, password: string) {

    await this.page.fill(this.usernameInput, username);

    await this.page.fill(this.passwordInput, password);

    await this.page.click(this.loginButton);

  }

}

2. login.spec.ts

import { test } from '@playwright/test';

import { LoginPage } from './LoginPage';

test('User can login', async ({ page }) => {

  const loginPage = new LoginPage(page);

  await page.goto('https://example.com/login');

  await loginPage.login('user1', 'password123');

});

Best Practices

  • Create one class per page or component.
  • Group reusable actions (e.g., login(), search()) as methods.
  • Use constants or locators to avoid hardcoding selectors multiple times.
  • Keep your POM files organized in a separate pages or pageObjects folder.

Conclusion

Using the Page Object Model with Playwright not only makes your test automation more modular and readable but also prepares your project for future scaling. As your application grows, maintaining clean, well-structured test code becomes crucial—and POM is the perfect way to achieve that.

Automated Regression Testing with Selenium

 Regression testing ensures that new code changes do not negatively impact the existing functionality of an application. As applications grow and evolve, manually performing regression tests becomes time-consuming and error-prone. Selenium, a leading open-source test automation tool for web applications, is an excellent choice for automating regression testing. What is Regression Testing? Regression testing involves re-running previously completed test cases after code changes to verify that existing features continue to work as expected. It is critical for maintaining application stability during frequent updates, especially in agile and DevOps environments. Why Use Selenium for Regression Testing? Selenium supports multiple browsers (Chrome, Firefox, Edge), programming languages (Java, Python, C#, etc.), and platforms. Its flexibility and integration capabilities make it ideal for building and executing automated regression test suites. Key Benefits: Open-source and community-sup...
