Selenium

Selenium is a groundbreaking automation testing library that transformed the tech world. It was conceived by the brilliant mind of Jason Huggins during his tenure at ThoughtWorks in 2004. Selenium is designed exclusively for automating web browsers and has a large ecosystem of open source projects that use Selenium and WebDriver as a key component to their functionality.

History of Selenium

Selenium was one of the first instances of an open source solution that actually drove a web browser. However, it started to cause a lot of bugs because of the JavaScript sandbox acting as a potential roadblock to the project's future. In 2007, Simon Stewart stepped in and embarked on a mission to develop the next generation, which is now Selenium WebDriver. This cutting-edge evolution of Selenium helped breathe new life into the platform, ensuring its continued success as a staple in the world of software testing.

Pros of Using Selenium

Selenium has a ton of language support, making it a virtual choice for testers who have a diverse coding skill set. It supports all the major browsers, including Chrome, Firefox, Safari, Internet Explorer, and Opera. It's also a W3 standard, making it a great choice for those who care about standards. Selenium has one of the largest communities of users, meaning there are plenty of resources, tutorials, and solutions available for common problems.

Cons of Using Selenium

Selenium tests can be slower compared to newer tools like Cypress and Playwright. Additionally, poorly developed tests can make them flaky and inconsistent, leading to false positives or negative results. Setting up Selenium can be complex, especially when it comes to configuring WebDriver for different browsers.

Cypress

Cypress is a developer-friendly testing tool that was designed to help developers write tests for the web. It was developed with a focus on three main things: setting up the tool in under 60 seconds, creating a writing experience that is fast and reliable, and helping in the maintenance cycle.

History of Cypress

Cypress was developed by Brian Mann, a developer who had been working in the field for 10 years and ran over 10,000 tests. He realized that the existing tools for automating testing were unreliable and too slow to use for test-driven development. He began experimenting with new technologies being introduced into browsers, like web sockets, with the goal of creating an underlying architecture that was less flaky and more powerful and ran faster.

Pros of Using Cypress

Cypress is a JavaScript-based testing framework designed to simplify the process of testing modern web applications. It allows developers to Create tests, bug them visually, and automatically run them in continuous integration builds. Cypress offers automatic weights for elements, which can be very useful in end-to-end testing where elements may not be immediately available. It also provides detailed error messages pointing to the exact line of code causing the issue and automatically records a video of the test run and makes a screenshot of the moment the test fails.

Cons of Using Cypress

Handling iframes in Cypress requires a plugin, which can be a disadvantage for developers who prefer a tool that can handle all aspects of end-to-end testing out of the box. Cypress has limited browser support and is a very opinionated tool, meaning you have to use or create Cypress tests the way Cypress wants you to.

Playwright

Playwright is the newest solution out of the three we've discussed and is a cross-browser automation library for end-to-end testing. It supports all the modern rendering engines like Chromium, WebKit, and Firefox and can be used across different platforms.

History of Playwright

Playwright started off as a fork of Puppeteer in 2019. It was designed for end-to-end testing of modern web applications and supports multiple programming languages, including TypeScript, JavaScript, Python, .NET, and Java.

Pros of Using Playwright

Playwright supports a variety of selectors, including text selectors, CSS selectors, XPath, and special selectors for different front-end frameworks like React and Vue. It also provides a selector playground in Visual Studio Code, which can help developers easily select elements on a page without having to manually inspect the DOM structure. Playwright supports multiple programming languages, making it a versatile choice for developers with different programming backgrounds.

Cons of Using Playwright

Playwright has a smaller community compared to Selenium and Cypress, meaning fewer resources and solutions to common problems. Some users find the Playwright API to be more complex compared to other tools, which could lead to a steeper learning curve.

Which One Should You Use?

There's not one right tool; there's only one right tool for you and your team. We recommend doing a proof of concept with all three tools and then deciding which one is right for your situation.

Conclusion

In conclusion, Selenium, Cypress, and Playwright are all great open source tools for automating web browsers. Each has its pros and cons, and the right tool for you depends on your specific needs and preferences. We hope this article has helped you make an informed decision about which tool to use for your web browser automation needs.
