Selenium is an umbrella project encapsulating a variety of tools and libraries enabling web browser automation.
It provides extensions to emulate user interaction with browsers, a distribution server for scaling browser allocation, and the infrastructure for implementations of the W3C WebDriver specification that lets you write interchangeable code for all major web browsers.
Selenium is open source software.
Tools include:
- At the core of Selenium is WebDriver, an interface to write instruction sets that can be run interchangeably in many browsers. WebDriver uses browser automation APIs provided by browser vendors to control browser and run tests. This is as if a real user is operating the browser. Since WebDriver does not require its API to be compiled with application code, it is not intrusive. Hence, it tests the same application which is pushed live.
- IDE (Integrated Development Environment) is the tool to develop your Selenium test cases. It’s an easy-to-use Chrome and Firefox extension and is generally the most efficient way to develop test cases. It offers simple record-and-playback of interactions with the browser in many different programming languages.
- Grid – allows you to run test cases in different machines across different platforms. The control of triggering the test cases is on the local end, and when the test cases are triggered, they are automatically executed by the remote end. The ability to run tests on remote browser instances is useful to spread the load of testing across several machines and to run tests in browsers running on different platforms or operating systems.
- Selenium client API – offers another alternative to writing of tests in Selenium. Selenium provides client APIs for Java, C#, Ruby, JavaScript, R and Python.
- Selenium Remote Control – write automated tests for the web applications in any programming language.
- Cross-platform support – runs under Linux, macOS, and Windows.
