Selenium Training Institute in VAISHALI

About  Selenium
This is a platform for testing software for web applications. Selenium provides a playback tool (previously also writing) to develop tests without having to learn the scripting language. It also provides a domain specific test language for writing tests in several programming languages, including C #, Groovy, Java, Perl, PHP, Python, Ruby and Scale. Then the tests can work against most modern web browsers. Testing of selenium is deployed on Windows, Linux and OS X. It is an open source software released under the Apache 2.0 license: web developers can download and use it without charge. Companies can run critical workloads or sensitive applications on private selenium by using public selenium tests or batch loads that need to be scaled on demand.

History of selenium
Selenium was originally developed by Jason Huggins in 2004 as an internal tool of ThoughtWorks. Later, they were joined by other programmers and testers at ThoughtWorks before Paul Hammant joined the team and led the development of the second mode of operation, which later becomes "Selenium Remote Control." This year the instrument was opened.
In 2005, Dan Fabulich and Nelson Sproul suggested adopting a series of patches that would turn Selenium-RC into what was best known. At the same meeting in Selenium, the management of selenium as a project will continue as a committee, and Huggins and Hammant will be representatives of "Thoughts".
In 2007, Huggins joined Google. Together with others, such as Jennifer Bevan, he continued to develop and stabilize Selenium RC. At the same time, Simon Stewart at ThoughtWorks developed an excellent browser automation tool called WebDriver. In 2009, after a meeting of developers at the Google Test Automation Conference, it was decided to combine two projects and name the new project Selenium WebDriver for Selenium 2.0.
Components of selenium testing
There are some components of selenium.
Selenium IDE
Selenium IDE(Integrated Development Environment) is a complete integrated development environment  (IDE) for Selenium tests. It is implemented as Firefox Add On and allows you to record using software, editing and debugging tests. Previously it was known as Selenium Recorder. It was originally created by Shinya Kasatani and transferred to the Selenium project in 2006. It is little supported and is compatible with Selenium RC, which was obsolete.
Selenium client API
The second component is selenium. As an alternative to writing tests in Selenium, tests can also be written in different programming languages. These tests are then linked to Selenium, calling methods in the Selenium Client API and testing selenium. Currently, Selenium provides client APIs for Java, C #, Ruby, JavaScript, and Python.
Selenium Remote Control
Selenium Remote Control (RC) is a component of selenium testing. This is a server written in Java, which accepts commands for the browser via HTTP. Selenium Remote Control allows you to write automatic tests for a web application in any programming language, which allows you to better integrate Selenium into existing modular test environments. To simplify the writing of tests, the Selenium project currently provides client drivers for PHP, Python, Ruby, .NET, Perl and Java. The Java driver can also be used with JavaScript. And a copy of the selenium RC server is required to run the test script html - this means that the port must be different for each parallel launch.


Selenium Grid
This is the last thing that is connected with the components of selenium. Selenium Grid is a server that allows you to test instances of a web browser running on remote computers. With Selenium Grid, one server acts as a hub. Tests communicate with the hub to access browser instances. The hub has a list of servers that provide access to browser instances, and allows you to test these instances. Thus, the Selenium Grid section allows you to run tests on several computers in parallel and centrally manage different versions of the browser and browser configurations.
Advantages
The first advantage is Selenium - a set of tools that helps automate only web applications. The Selenium IDE software is a plug-in for Firefox that allows testers to record their actions following the technological process that they need to test. Selenium WebDriver is the successor to Selenium RC, which sends commands directly to the browser and retrieves the results.
Disadvantages
  • supports only web based applications.
  • No IDE, so the script development won't be fast
  • Cannot access controls within the browser.
  • No default test report generation.
