The server acts as a client configured HTTP proxy and 'tricks' the browser into believing that Selenium Core and the web application being tested share the same origin. This is called the Same Origin Policy, and Selenium RC was introduced to address this limitation. Local copies of Selenium-Core and the web browser had to be installed so that they belonged to the same domain. However, the program cannot access elements of other domains like. This program can access pages like /mail or /login within the domain. Now, let’s consider a JavaScript, test.js used by. Selenium-Core was then injected into the web browser. It was a set of JavaScript functions that interpreted and executed Selenese commands using the browser's built-in JavaScript interpreter. Initially, Selenium-Core was called 'JavaScriptTestRunner,' a tool built by Jason Huggins in 2004.

Paul Hammant developed Selenium Remote Control. It also covers the reason why RC came into existence in the first place.

Selenium consists of a set of tools that facilitate the testing process.Īnother interesting topic that this Selenium automation testing tutorial covers is Remote Control or RC. However, tools like Appium and HP’s QTP, among others, can be used to test software and mobile applications. One disadvantage of Selenium automation testing is that it works only for web applications, which leaves desktop and mobile apps out in the cold. This program was renamed Selenium in 2004. He developed a JavaScript program called the JavaScriptTestRunner that automated web application testing. To overcome these obstacles, Jason Huggins, an engineer at Thoughtworks, decided to automate the testing process. Manual testing, a vital part of the application development process, unfortunately, has many shortcomings, chief of them being that the process is monotonous and repetitive. Introduction to Selenium Automation Testingīut before we explore this Selenium automation testing tutorial, let’s first address the need for Selenium automation testing and how Selenium came into the picture in the first place.
