Playwright with TypeScript: Tips for Beginners

 In the world of web automation and end-to-end testing, Playwright has emerged as a powerful tool developed by Microsoft. With support for modern frameworks and multiple browsers, it enables reliable and fast testing across Chromium, Firefox, and WebKit. When combined with TypeScript, Playwright offers better type safety, code completion, and maintainability—making it a great choice for developers. If you're just getting started, here are some essential tips to help you succeed with Playwright and TypeScript.

What is Playwright?

Playwright is an open-source automation library that allows developers to write tests for web applications using JavaScript or TypeScript. It supports features like:

  • Multi-browser support
  • Headless and headed modes
  • Automatic waiting
  • Rich API for interacting with web elements

Why Use TypeScript with Playwright?

TypeScript is a typed superset of JavaScript that adds optional static typing. Using TypeScript with Playwright:

  • Reduces runtime errors
  • Provides better code suggestions
  • Helps with scalability and large projects
  • Getting Started with Playwright and TypeScript
  • Install Playwright with TypeScript

Use the following commands to set up your project:

bash

Copy

Edit

npm init -y

npm i -D playwright typescript ts-node @types/node

npx playwright install

Configure TypeScript

Create a tsconfig.json file:

json

Copy

Edit

{

  "compilerOptions": {

    "target": "ESNext",

    "module": "commonjs",

    "strict": true,

    "esModuleInterop": true,

    "skipLibCheck": true

  }

}

Write Your First Test

Example: example.test.ts

typescript

Copy

Edit

import { chromium } from 'playwright';

(async () => {

  const browser = await chromium.launch();

  const page = await browser.newPage();

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

  console.log(await page.title());

  await browser.close();

})();

Run the Test

Execute the script using:

bash

Copy

Edit

npx ts-node example.test.ts

Tips for Beginners

Use Page Object Model (POM): It organizes your tests and promotes reusability.

Leverage Playwright Test Runner: It supports fixtures, parallel execution, and rich reporting.

Debug with ease: Use headless: false and slowMo for visual debugging.

Explore Auto-Waiting: Playwright waits for elements to be ready before interacting, reducing flakiness.

Use Built-in Assertions: Type-safe assertions improve reliability.

Conclusion

Playwright with TypeScript is a powerful combination for modern web testing. By starting with proper setup, using TypeScript’s features, and following best practices, beginners can build efficient, maintainable, and scalable test automation suites with ease

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...
