Selenium Webdriver is a widely used tool for the automated testing of web applications. It has become popular because you can control and interact with an application the same way a user would with an actual web browser. Selenium can automate every action a user would take in a browser on multiple operating systems and using multiple browsers, including Chrome, Firefox, Edge, Internet Explorer, and Safari. This means it can be used to test that some functionality works the same in all supported browsers. Webdriver is how you interact with Selenium. It is a simple programming interface that you interact with by writing code and calling its API. Scripts to run Selenium Webdriver can be written in Java, JavaScript, C#, and Python. You can even take screenshots during the testing process to determine the state of the page during the test.

Selenium Webdriver is used in any job requiring automated testing of web applications. It is used by automation architects whose job duties involve automating various applications and services throughout an enterprise, including testing web applications. It is used by test automation engineers who specialize in creating automated web application tests. QA testers can use Selenium Webdriver in their job to automate some of their tests while they test other parts of the application manually. Selenium Webdriver is the main tool used by Selenium automation engineers. Some other careers requiring Selenium Webdriver include Selenium tester, senior QA automation engineer, Selenium test analyst, and software development test engineer.

While Selenium Webdriver is easy to learn and makes the job of a web application tester simpler, there are some skills you should have before you learn how to use it. First, you need to know the basics of software testing to know what should be tested on a web application to ensure it works. This includes knowing what test cases, defects, manual testing, regression testing, and automation testing are. Since Selenium Webdriver interacts with web pages, you need to know the basics of web technologies. This includes knowing HTML, CSS, Xpath, DOM, JavaScript, and XML. While you don't have to be an expert programmer, you do need to know the basics of writing scripts in one of the languages that Selenium Webdriver understands. These programming languages include Java, JavaScript, C#, and Python.
