Playwright Installation and Configuration Guide

 Playwright is an open-source test automation framework developed by Microsoft. It enables fast and reliable end-to-end testing for modern web applications across multiple browsers such as Chromium, Firefox, and WebKit. If you're looking to automate UI testing with minimal flakiness and powerful features, Playwright is a top choice.

This guide walks you through the installation and basic configuration of Playwright.

Prerequisites

Before installing Playwright, ensure the following:

Node.js (version 14 or later) is installed.

Check with:

bash

Copy

Edit

node -v

npm (Node Package Manager) is available.

You can install Node.js from https://nodejs.org.

Installing Playwright

To install Playwright, open your terminal and run:

bash

Copy

Edit

npm init playwright@latest

This command will:

Set up a new testing project

Install Playwright and its dependencies

Let you choose between JavaScript or TypeScript

Ask if you want to include GitHub Actions for CI

Alternatively, you can manually install it in an existing project:

bash

Copy

Edit

npm install -D @playwright/test

npx playwright install

The second command downloads browser binaries for Chromium, Firefox, and WebKit.

Folder Structure

After installation, your project directory might look like this:

lua

Copy

Edit

my-project/

├── tests/

│   └── example.spec.js

├── playwright.config.js

├── package.json

└── node_modules/

tests/: Folder for your test scripts

playwright.config.js: Configuration file for your test setup

Writing Your First Test

Create a test file inside the tests folder:

javascript

Copy

Edit

// tests/example.spec.js

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

test('basic page title test', async ({ page }) => {

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

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

});

Run the test using:

bash

Copy

Edit

npx playwright test

You’ll see output showing test execution and results.

Customizing Configuration

In playwright.config.js, you can define:

Test timeout

Parallelism

Browsers to test

Base URL for tests

Reporting options

Example:

javascript

Copy

Edit

module.exports = {

  timeout: 30000,

  use: {

    browserName: 'chromium',

    headless: true,

  },

};

Conclusion

Playwright makes it easy to write fast, reliable browser tests with modern automation capabilities. With simple installation, cross-browser support, and powerful configuration options, it’s ideal for developers and QA teams aiming for robust UI testing.

SoapUI for API Testing: A Beginner’s Guide

 APIs are the backbone of modern applications, enabling communication between different software systems. Testing these APIs is crucial to ensure reliable performance and functionality. SoapUI is one of the most widely used tools for API testing, especially for SOAP and REST services. This beginner’s guide will walk you through what SoapUI is, why it's useful, and how to get started. What is SoapUI? SoapUI is an open-source tool designed for testing web services. It supports both SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) APIs. SoapUI offers a user-friendly interface that makes it easier to send requests, inspect responses, automate tests, and validate data. Why Use SoapUI for API Testing? Easy to use GUI with drag-and-drop features Supports both manual and automated testing Allows functional, security, and performance testing Supports data-driven testing using external sources Enables testers to mock web services for testing in isolated environ...

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...
