What is Selenium?

Selenium is an open source umbrella project for a range of tools and libraries aimed at supporting browser automation. It provides a playback tool for authoring functional tests across most modern web browsers, without the need to learn a test scripting language.

Why do we need Selenium?

Most programmers and developers who build website applications and wish to test them every now and then use Selenium. One of the biggest advantages of Selenium, which has made it so popular, is its flexibility. Any individual who creates web programs can use Selenium to test the code and applications. Further, professionals can debug and perform visual regression tests as per the requirements of the website or code.

In most organisations, it is the job of quality analyst (QA) engineers to test web applications by using Selenium. They are required to write scripts that can help in maximising accuracy and test coverage to make changes in the project and maintain the infrastructure of the test.
