An important part, of any project, is well-written tests. Often in our work as programmers, we look for solutions to speed up our work or to automate it. In this article, I will introduce the Selenium tool that will help us automate tests.
What is Selenium?
Selenium Webdriver, Selenium IDE and Selenium Grid.
Selenium provides us with a pair of tools to work with, which each have a specific role in supporting the automation of web application testing.
Selenium Webdriver - Simulates the browser user experience and uses it as if a real user were doing it. With a simple configuration, WebDriver can be used in all the most popular browsers such as: Firefox, Safari, Edge, Chrome, Internet Explorer.
Selenium IDE - This is an extension for browsers such as Chrome, Firefox and Edge that makes it easy to record and playback tests in the browser.
Selenium Grid - Allows WebDriver to run tests on multiple computers at the same time, reducing the time needed to test on multiple browsers and operating systems.
