Differences Between Selenium and Playwright
Differences Between Selenium and Playwright
Automation testing is an essential practice in software development, allowing testers to automate repetitive tasks and ensure software quality. Selenium and Playwright are two popular tools used for web automation testing. While both serve the same purpose, they have different features, architectures, and use cases.
What is Selenium?
Selenium is a widely used open-source automation framework that enables testers to automate web applications across different browsers. It supports multiple programming languages like Java, Python, C#, and JavaScript. Selenium provides various components like Selenium WebDriver, Selenium Grid, and Selenium IDE to facilitate browser automation.
- Supports multiple browsers, including Chrome, Firefox, Safari, and Edge.
- Allows integration with various testing frameworks like JUnit and TestNG.
- Provides cross-platform compatibility.
- Has a large community and extensive documentation.
What is Playwright?
Playwright is a modern automation testing tool developed by Microsoft, designed for end-to-end testing of web applications. It supports multiple browsers and provides powerful features for handling automation challenges. Playwright supports JavaScript, TypeScript, Python, Java, and C#.
- Provides built-in support for multiple browsers (Chromium, Firefox, and WebKit).
- Offers automatic waiting and smart assertions.
- Supports headless and headful browser execution.
- Allows testing of mobile web applications.
Selenium vs. Playwright
