What Is Selenium?
Selenium is probably going probably the most well-established software within the discipline of automated browser testing (over 35,000 corporations reported utilizing Selenium in 2025).
Initially launched in 2004, it has grown to turn out to be the de facto business commonplace for useful testing of net purposes. Whereas many of the present instruments for automated testing characterize one product, Selenium represents a set of instruments:
- Selenium WebDriver: The underlying API upon which builders write check scripts and discuss to browsers.
- Selenium IDE: A record-and-playback software that could be utilized even by non-tech customers to construct easy check circumstances.
- Selenium Grid: A system for operating assessments in parallel on quite a few machines, which is important for in depth software program testing.
Within the background, Selenium is definitely applied on high of the WebDriver protocol. It interprets check instructions into JSON, sends them over HTTP to browser drivers, after which makes them execute inside the browser. This structure has labored nicely for generations, although it does come at some efficiency expense.
What distinguishes Selenium is its protection. Selenium gives help for almost all of the outstanding programming languages (Java, Python, C#, PHP, and JavaScript) and all the highest browsers (Chrome, Firefox, Safari, Edge, and even Web Explorer).
With 20 years of utilization, it additionally has an enormous group, in depth CI/CD pipeline integration, and an abundance of documentation and tutorials.
What Is Playwright?
Constructed by Microsoft and made accessible in 2020, Playwright was created with fashionable net growth in thoughts to resolve a variety of the problems testers have been dealing with when making use of Selenium for browser automation.
