Using Playwright with JavaScript

 In the world of web automation and end-to-end testing, Playwright has emerged as a powerful and modern tool. Developed by Microsoft, Playwright supports multiple browsers, languages, and platforms. When paired with JavaScript, it becomes an excellent choice for developers and testers looking to automate UI testing quickly and efficiently.

What is Playwright?

Playwright is an open-source Node.js library for browser automation. It enables developers to write scripts that can interact with websites the same way a real user would — clicking buttons, filling forms, navigating pages, and more.

Unlike traditional automation tools, Playwright supports Chromium, Firefox, and WebKit out of the box and allows testing across Windows, Linux, and macOS.

Why Use Playwright with JavaScript?

Easy to Learn: JavaScript is widely known and used, making Playwright accessible to a large developer base.

Cross-Browser Support: Write once, test across Chrome, Safari, and Firefox.

Headless and Headful Modes: Run tests silently in the background or visually during debugging.

Fast and Reliable: Auto-waiting for elements and built-in retries reduce test flakiness.

Getting Started with Playwright and JavaScript

Install Playwright

First, set up a Node.js project and install Playwright:

bash

Copy

Edit

npm init -y

npm install @playwright/test

npx playwright install

Write Your First Test

Create a test file, e.g., example.spec.js:

javascript

Copy

Edit

const { test, expect } = require('@playwright/test');

test('homepage should have title', async ({ page }) => {

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

  await expect(page).toHaveTitle(/Example Domain/);

});

Run the Test

Use the Playwright Test Runner:

bash

Copy

Edit

npx playwright test

Core Features

Screenshots and Videos: Automatically capture visuals on test failure.

Parallel Execution: Speed up tests by running them in parallel.

Built-in Test Generator: Generate test scripts by recording user actions.

bash

Copy

Edit

npx playwright codegen https://example.com

Conclusion

Playwright with JavaScript is a robust solution for modern web testing. It’s fast, flexible, and easy to set up, making it ideal for both beginners and experienced QA engineers. Whether you're building a new test suite or replacing a legacy one, Playwright provides the tools needed to ensure your web application runs flawlessly across all browsers.

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...

Containerizing Java Apps with Docker and Kubernetes

 Modern application development demands speed, scalability, and consistency across environments. Containerization addresses these needs by packaging applications and their dependencies into lightweight containers. For Java applications, using tools like Docker and Kubernetes simplifies deployment, scaling, and management. In this blog, we'll explore how to containerize a Java app with Docker and manage it using Kubernetes. Why Containerize Java Applications? Java apps often depend on specific versions of libraries, Java Runtime Environment (JRE), and configurations. Containers: Ensure consistency across dev, test, and production environments Simplify dependency management Improve portability and scalability Enable microservices architecture Step 1: Create a Java Application Let’s assume you have a simple Spring Boot application with a jar file ready for deployment: ./mvnw clean package This generates a .jar file in the target/ directory. Step 2: Write a Dockerfile Create a file nam...
