Selenium vs. Playwright
Both Selenium and Playwright are open-source software tools that allow developers to automate tasks on web browsers and perform automated testing on web applications. They are both widely used in the software development industry and are popular choices for automated testing due to their flexibility and extensive feature sets.
One key difference between Selenium and Playwright is that Selenium has been around for longer and has a more extensive user base, which means it has a more established ecosystem of documentation, support, and integrations with other tools. Selenium also supports a wider range of programming languages and browser environments, which may make it a more attractive choice for some developers.
On the other hand, Playwright is a newer tool developed by Microsoft and has a more focused feature set. It is built on top of the web standards-based browser automation library called WebKit, which allows it to automate tasks on modern web browsers such as Google Chrome, Microsoft Edge, and Apple Safari. Playwright is designed to be easy to use and includes a range of features and functionality to make it simple for developers to write, maintain, and run automated tests.
Here are some key differences between Selenium and Playwright:
- Age and user base: Selenium has been around for longer and has a larger user base, which means it has a more established ecosystem of documentation, support, and integrations with other tools.
- Supported programming languages: Selenium supports scripting in multiple programming languages, including Java, Python, C#, Ruby, and more. Playwright supports scripting in JavaScript, Python, and C#.
- Supported browser environments: Selenium supports automation on a wide range of web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, Apple Safari, and more.
