Selenium Testing is a standard open-source electronic motorization instrument. Selenium is a strong game plan of instruments that support expedient headway of test automation for online applications. Selenium equips a record playback mechanical assembly to form tests without anchoring a test scripting vernacular.

SELENIUM?

Selenium is an open source instrument which is utilized for mechanizing the tests completed on internet browsers (Web applications are tried utilizing any internet browser).

Pause, before you escape, let me re-emphasize that, just testing of web applications is conceivable with Selenium. We can neither test any work area (programming) application nor test any versatile application utilizing Selenium.

Test scripts can be written     in any of these programming languages: Java, Python, C#, PHP, Ruby, Perl & .Net

Tests can be carried out in     any of these OS: Windows, Mac or Linux

Tests can be carried out     using any browser: Mozilla Firefox, Internet Explorer, Google     Chrome, Safari or Opera

It can be integrated with     tools such as TestNG & JUnit for     managing test cases and generating reports.

NEED FOR SOFTWARE TESTING:

Programming testing is the place everything comes down to. The present universe of innovation is totally commanded by machines, and their conduct is constrained by the product driving it. Will the machines carry on precisely as we need them to? Everytime? All over the place? The response to these inquiries lie in programming testing.

Toward the day's end, it is the product application's prosperity rate which is going to control your business development. A similar thing can be said notwithstanding for web applications in light of the fact that most organizations today are totally dependent on the web.

Take for instance, any internet business organization. Be it Amazon or E-Bay or Flipkart, they depend on the client traffic on their sites and traffic on their electronic versatile applications for business. Envision, if something disastrous happens like the costs of various items being topped off at 10$, all due to a little bug in a "not all that effectively meaningful" some portion of the code. At that point what should be possible, and how might we forestall it whenever?

By testing the code before arrangement right? Along these lines, that is the requirement for programming testing. Be that as it may, what is Selenium? Is it a product testing device? All things considered, Selenium is a computerization testing apparatus! Before I go any further, let me get out that, Software testing is of two sorts: Manual Testing and Automation Testing. Selenium was established as a computerization testing instrument to defeat the downsides/restrictions of Manual testing. Along these lines, in the following area of this what is selenium blog, how about we comprehend the difficulties with manual testing.

SELENIUM TOOLS

Selenium RC

Selenium IDE

Selenium Grid

Selenium WebDriver

SELENIUM RC

Before I talk about the subtleties of Selenium RC, I might want to go a stage back and talk about the primary apparatus in the Selenium venture. Selenium Core was the principal apparatus. In any case, Selenium Core hit a barricade as far as cross-area testing in light of a similar cause arrangement. Same inception arrangement restricts JavaScript code from getting to web components which are facilitated on an alternate area contrasted with where the JavaScript was propelled.

To conquer a similar birthplace strategy issue, analyzers expected to introduce nearby duplicates of both Selenium Core (a JavaScript program) and the web server containing the web application being tried so they would have a place with a similar space. The lasting answer for this issue ended up being Selenium RC. What does RC do at that point?

SELENIUM IDE

Selenium IDE is a Firefox module which is utilized to rapidly and much of the time, record and execute test cases. Experiments in IDE are made by chronicle the collaborations which the client had with the internet browser. These tests would then be able to be played back any number of times.

The preferred standpoint with Selenium IDE is that, tests recorded by means of the module can be traded in various programming dialects like: Java, Ruby, Python and so on. Look at the beneath screen capture of Firefox's IDE module.

SELENIUM GRID

Selenium Grid was a piece of Selenium v1 and it was utilized in blend with RC to run tests on remote machines. Truth be told, with Grid, different test contents can be executed in the meantime on numerous machines.

Parallel execution is accomplished with the assistance of Hub-Node design. One machine will expect the job of Hub and the others will be the Nodes. Center point controls the test contents running on different programs inside different working frameworks. Test contents being executed on various Nodes can be written in various programming dialects.

SELENIUM WEBDRIVER

As opposed to IDE, Selenium WebDriver gives a programming interface to make and execute test cases. Experiments are composed with the end goal that, web components on site pages are recognized and afterward activities are performed on those components.

WebDriver is a move up to RC in light of the fact that it is a lot quicker. It is quicker on the grounds that it makes guide calls to the program. RC then again needs a RC server to collaborate with the internet browser. Every program has its own driver on which the application runs.

CONCLUSION

Selenium is the most needed technology because it has bright future in it, there is a huge job opportunity in the IT.
