Selenium is a free automated software tool for validating web applications across multiple browsers and operating systems. Selenium Test Scripts may be written in a variety of computer languages, including Java, C Language, and Python. Selenium Testing is the term used to describe testing performed with the Selenium testing tool. Selenium Tools is a suite of software, each piece serving a distinct organization's Selenium QA testing needs.
The following may be a list of tools.
Due to the constraints enforced by the same origin policy, testers using Selenium Core had to install the whole software under test as well as the webserver on their own local machines. Yet another ThoughtWorks developer, Paul Hammant, decided to build a server that will operate as an HTTP proxy to "fool" the search engine into thinking Selenium Core and the web application being tested are of the same domain. The Selenium Remote Control, or Selenium 1, was the name given to this technology.
Patrick Lightbody created Selenium Grid to answer the requirement to reduce test completion time as much as feasible. He first referred to the system as "Hosted QA." It was capable of taking browser screenshots for critical phases, as well as transmitting Selenium commands to many machines at the same time.
Shinya Kasatani of Japan invented Selenium IDE, a Firefox plugin that can automate the search engine using a record-and-playback function. He came up with this concept to speed up the process of developing test cases.
Selenium 2's Arrival:
In 2008, the Selenium Team as a whole chose to combine WebDriver and Selenium RC to create a more powerful tool dubbed Selenium 2, with WebDriver as its heart. Selenium RC is still being built at the moment, although solely in a maintenance mode. The majority of the Selenium Project's efforts are currently directed toward Selenium 2.
The name Selenium was inspired by a joke Jason told his colleagues. During the development of Selenium, another automated testing framework known as Mercury Interactive was popular (yes, the company that originally made QTP before it was acquired by HP). Jason offered the name Selenium since it is a well-known remedy for Mercury toxicity, and his teammates adopted it. So that's how we arrived at the present-day name for this system.
The Selenium Integrated Development Environment (IDE) is the most basic structure in the Selenium suite and the most straightforward to grasp. It is a Firefox plugin that you may install just like any other plugin. Selenium IDE, on the other hand, can only be used as a prototype tool because to its ease. If you wish to construct more complex test cases, you'll need to utilise Selenium RC or WebDriver.
For a long period of time, Selenium RC was the flagship framework for building the whole Selenium project. This is the first automated web testing solution that allows customers to utilise their own software program. RC can now handle the following scripting language as of version 2.25.0:
Grid of Selenium:
Selenium Grid is a solution that works in tandem with Selenium RC to conduct simultaneous tests on several workstations and browsers at the same time. Parallel execution entails executing many tests at the same time.
