What is Selenium? Selenium is a free (open source) computerized testing suite for web applications crosswise over various programs and stages. It is very like HP Quick Test Pro (QTP now UFT) just that Selenium centers around robotizing electronic applications. Testing done utilizing Selenium instrument is normally alluded as Selenium Testing.
Main Parts of Selenium: Selenium isn't only a solitary device however a suite of software's, each taking into account distinctive testing needs of an association. It has four parts. (i)Selenium Integrated Development Environment (IDE) (ii)Selenium Remote Control (RC) (iii)WebDriver (iv)Selenium Grid
Introduction Selenium IDE: • Selenium Integrated Development Environment (IDE)Is the most • straightforward system in the Selenium suite and is the least • demanding one to learn. • It is a Firefox module that you can introduce as effectively as you can • with different modules. • In any case, in light of its effortlessness, Selenium IDE should just be • utilized as a prototyping instrument. • On the off chance that you need to make further developed • experiments, you should utilize either Selenium RC or WebDriver.
Presentation Selenium Remote Control (Selenium RC): • Selenium RC was the flagship trying framework of the entire • Selenium venture for quite a while. • This is the principal robotized web testing apparatus that allowed • clients to utilize a programming dialect they learn toward. • As of variant 2.25.0, RC can bolster the accompanying programming dialects: • (1)Java • (2) C# • (3)Python • (4)Perl • (5)Ruby
Selenium Grid: • Selenium Grid is a device utilized together with Selenium RC to run • parallel tests crosswise over various machines and distinctive programs • all in the meantime. Parallel execution implies running various tests on • the double. • Highlights: • Empowers synchronous running of tests in numerous programs and • situations. • Spares time tremendously. • Uses the center and-hubs idea. • The center point goes about as a focal wellspring of Selenium orders to every hub associated with it.
Advantages in Selenium: • 1.Open-Source: • As specified before, the greatest quality of Selenium is that it is a freeware and a compact apparatus. It has no forthright direct costs included. The instrument can be uninhibitedly downloaded and the help for it is unreservedly accessible, as it is group based. • 2.Backings dialects: • Selenium bolsters a scope of dialects, including Java, Perl, Python, C#, Ruby, Groovy, Java Script, and so on. It has its own particular content, however it doesn't restrain it to that dialect. • 3.Backings Operating Systems: • Selenium can work and support over different Operating Systems(OS) like Windows, Mac, Linux, UNIX, and so on. With Selenium Suite of arrangements, a customized testing suite can be made over any stage and after that executed on another. For example, you can make test cases utilizing Windows OS and run it easily on a Linux based framework.
Drawbacks of Selenium: • Selenium prerequisites extraordinarily information resources. The • source likewise should be superbly experienced in system structures. • Selenium just encourages web based application and doesn't help windows-based programming. • It's trying to check picture based programming. • Selenium require outside help with respect to proclamation innovation practice like dependence on TestNG or Jenkins. • Selenium doesn't bolster worked in include ins help. • Selenium individual needs online help for that issues they experience. • Selenium doesn't supply any implicit IDE in regards to programming period likewise it require extra IDE like Eclipse with respect to making programs.
