Selenium is a standout among the most prominent instruments for program based testing. It is an Open Source extend that has picked up a great deal of ubiquity in the most recent couple of years. Despite the fact that there are other Open Source (free) apparatuses that can test a web application, as HttpUnit, HtmlUnit and so forth, this was one of the first devices that gave a genuine different option for business devices like Quick Test Pro (QTP), WinRunner, Silk and others that had increased huge appropriation by the QA Engineers. There are a couple calculates that have ascribed to Selenium’s prosperity. Since this is a free instrument, it regularly is one of only a handful couple of choices for organizations that don’t have a great deal of spending plan for Automation apparatuses.
Selenium was first composed in Java yet it additionally backings .Net, Ruby, Perl, PHP and Python. This is a major in addition to when you need to construct your structure in a dialect that has the most noteworthy selection in the association it is being manufactured inside. Devices like QTP compel you to utilize VBScript – which is never the favoured scripting dialect for engineers. Since this instantiates and drives a genuine program, instead of recreated program arrangements like HtmlUnit, this device keeps running in a customer that is closer to what a genuine client would utilize. This thusly gives more certainty that tests keep running with this instrument would get most issues that a genuine client would encounter. It has support for the greater part of the well-known programs like IE, Firefox, Chrome, Safari and so on. It additionally underpins a few Operating Systems and that settles on it an instrument of decision for cross program/cross stage affirmation.
The engineer group of Selenium are continually attempting to push the envelope of what can be accomplished with program robotization. Customizable, key press activities, flex bolster and so on are a few samples of this. Other than that, there are organizations like Sauce Labs who are give an administration called Sauce On Demand which is a cloud benefit that permits clients to execute their Selenium scripts in parallel. When you get Selenium to work for you, it lives up to expectations dependably when utilized for running the tests again and again. It’s unquestionably a ton more solid than apparatuses like QEngine or JExplorer yet about the same as instruments prefer QTP.
