2. What is selenium? Selenium is a portable software-testing framework for web applications. Selenium provides a playback (formerly also recording) tool for authoring tests without the need to learn a test scripting language (Selenium IDE). It also provides a test domain- specific language (Selenese) to write tests in a number of popular programming languages, including C#, Groovy, Java, Perl, PHP, Python, Ruby and Scala. Selenium is not just a tool, it is a software package that meets the different testing needs of each organization. There are four components.  selenium integrated development environment (ide)  selenium remote control (rc)  WebDrive  selenium grid

4. Who developed Selenium? There were also different developers because Selenium was a collection of different vehicles. Below are some important contributors to the selenium project. First, selenium was created by Jason Huggins in 2004. An engineer in his idea was working on a web application that should be tested frequently. Recognizing that the repetitive manual tests of his applications have become increasingly inefficient, he has created a JavaScript program that will automatically validate the browser's actions. This program was named "JavaScriptTestRunner". This application has the potential to help automate another web application, then the core JavaScriptRunn is called selenium open source.

5. Birth of IDE(selenium rc) Unfortunately, testers who use selenium core have to test all web server applications and set up their own local computers because of the restrictions imposed by policies from the same source.

This system is known as selenium or selenium 1 remote control.

7. Selenium-WebDriver Selenium-WebDriver supports the following browsers along with the operating systems these browsers are compatible with. Google Chrome Internet Explorer 7, 8, 9, 10, and 11 on appropriate combinations of Vista, Windows 7, Windows 8, and Windows 8.1. As of April 15 2014, IE 6 is no longer supported. The driver supports running 32-bit and 64-bit versions of the browser where applicable. Firefox: latest ESR, previous ESR, current release, one previous release

8. Safari Opera HtmlUnit phantomjs Android (with Selendroid or appium) iOS (with ios-driver or appium)

9. Birth of the selenium grid The Selenium grid has been developed by Patrick LightBody to meet the need to reduce test times as much as possible. Selenium online training At the beginning, he called the system "qa". Critical screens had the ability to capture browser screenshots and send selenium commands to different machines at the same time.

10. Birth of the Selenium IDE Shinya Kasatani, from Japan, created the Selenium IDE, a Firefox add-on that can automate recording and playback and the browser. He created this idea to further accelerate the test scenario. He donated the Selenium IDE for the Selenium Project in 2006. Best selenium trianing in chennai
