One of the greatest difficulties in working with open source programming is discovering great documentation on their use and functionalities. Selenium, tragically, isn't absolved from lacking fantastic assets. The facts confirm that everything can be found on the Internet; however it is likewise evident that not everything on the Internet is of good, exact quality.

A basic look at all the authority or formally associated documentations uncovers that they are ineffectively composed, irrationally composed, and at last unsympathetic for new analyzers. To get something in Selenium working in any case, an analyzer will probably need to scour online sites and discussions for a considerable length of time before knowing the best possible advances and best practices.

Webdriver is a stage and language-unbiased interface that enables you to program or content, and control the conduct of an internet browser. The WebDriver API is essentially planned to enable designers to compose tests that computerize a program from a different controlling procedure, however may likewise be executed selenium training in Bangalore so as to permit in-program contents to control a conceivably discrete program.

Selenium Webdriver (Selenium 2) has effectively defeated the constraints of Selenium RC (Selenium 1) by integrating basic Webdriver API.

i.e., Selenium 1.0 + WebDriver = Selenium 2.0

WebDriver is structured and created to give a more straightforward, progressively brief programming interface and to all the more likely help dynamic pages where components of a page may change without the page itself being reloaded. WebDriver objective is to supply a very much planned article arranged API that gives improved help to present day propelled web-application testing issues.
Not at all like Selenium RC, there is no compelling reason to begin the Selenium server unfailingly. It relies upon how the Selenium Webdriver is utilized. On the off chance that program and tests will all keep running on a similar machine, and the tests just utilize the WebDriver API, at that point there isn't have to run the Selenium-Server, WebDriver will run the program straightforwardly.

There are a few reasons however to utilize the Selenium-Server with Selenium-WebDriver:

• When Selenium-Grid is utilized to convey your tests over various machines or virtual machines (VMs).
• When there is a need to interface with a remote machine that has a specific program form that isn't on your present machine.
• When Java ties are not used (i.e. Python, C#, or Ruby) and might want to utilize HtmlUnit Driver.

Since Selenium WebDriver is broadly utilized in Automation, it ended up imperative for the Selenium WebDriver to be utilized in a progressively profitable manner. There are Frameworks accessible that can be utilized alongside the WebDriver like JUnit, TestNG, which sorts out the Test contents bitterly.


JUnit is a unit testing structure for the Java programming language. JUnit has been essential in the advancement of test-driven improvement, and is one of a group of unit testing structures.

Test techniques must be clarified by the @Test explanation. On the off chance that the circumstance requires, it is likewise conceivable to characterize a technique to execute previously (or after) each (or all) of the test strategies with the @Before (or @After) and @BeforeClass (or @AfterClass) comments.


TestNG is a trying system that beats the constraints of another prominent testing structure called JUnit. The "NG" signifies "People to come". Most Selenium clients utilize this more than JUnit in view of its focal points. There are such a significant number of highlights of TestNG, yet we will just concentrate on the most imperative ones that we can use in Selenium.

On the off chance that it is some fundamental Unit Testing, both the structures are essentially the equivalent. Both the structures enable you to test the code in a fast and powerful way. They have had apparatus support in Eclipse and other IDE. They have additionally had help in the assemble structures like Ant and Maven. First of all JUnit has dependably been the decision since it was the primary system for Unit testing and has dependably been accessible.
JUnit Test Suites and ventures can be relocated to TestNG. The least demanding approach to change over your JUnit tests to TestNG is to utilize the Eclipse TestNG module refactoring support.

TestNG is intended for abnormal state testing and complex reconciliation test. Its adaptability is particularly helpful with huge test suites. Furthermore, TestNG additionally spread the whole center JUnit4 usefulness. It's simply no purpose behind me to utilize JUnit any longer.
WebDriver is a perfect, quick structure for robotized testing of Webapps. It adopts an alternate strategy to take care of indistinguishable issue from Selenium. As opposed to being a JavaScript application running inside the program, it utilizes whichever system is most fitting to Selenium Courses in Bangalore control the program. For Firefox, this implies WebDriver is executed as an expansion.

For IE, WebDriver makes utilization of IE's Automation controls. By changing the instrument used to control the program, we can bypass the limitations put on the program by the JavaScript security display. In those situations where robotization through the program isn't sufficient, WebDriver can make utilization of offices offered by the Operating System. It was one of the primary Open Source activities to convey program based testing to the majority, and in light of the fact that it's written in JavaScript it's conceivable to rapidly include support for new programs that may be discharged.
