Introduction and Features of Selenium Webdriver

Selenium WebDriver a standout amongst the most key part of SELENIUM Releases and on which flow Automation industry thoroughly depend on, particularly on the off chance that we say "Open Source Community".

What is WebDriver?

In basic and simple dialect on the off chance that we say then "It is an API that is anything but difficult to investigate and comprehend, which help us to make our tests less demanding to peruse and keep up." WebDriver isn't connected to any sort of Test Framework or Tool and this makes this API more valuable as we can utilize the same according to our requirements or information of other incorporation open sources like JUNIT, TestNG and so on.

• An all-around outlined Object Oriented API that gives enhanced help to web-application testing issues.
• Supports dynamic website pages where component of a Page may change without the Page itself being reloaded.
• All the constraints of SELENIUM RC amended in this Selenium WebDriver.

Selenium RC Limitations:-

1. Work utilizing Java content infusion prompts same starting point arrangement issues. WebDriver beats this constraint by having driver for every program.
2. RC means Remote Control, while executing tests utilizing Selenium RC it is evident to have Selenium RC Server between Application under test and Test Automation Suite. This strategy of Client Server engineering of Selenium RC makes it slower than Selenium Web Driver.
3. Redundancy of summons
4. RC can't bolster headless program however WebDriver can.

WebDriver Architecture:-

• WebDriver actualized on Layered Design, the thought behind this execution is increasingly use of WebDriver for computerization and this could be conceivable by fitting best fit dialects.
• Implementation of WebDriver is that every program has a dialect that is most normal to utilize when endeavoring to drive it. Drivers are worked according to the best fit dialect and we can simply observe the wrapper around them.
• We can state that for any of program driver if any of the highlights works there in one restricting dialect then it ought to be anything but difficult to add support to other restricting dialects too.
• Web Driver is a reduced Object Oriented API which can specifically connects with the Application under tests.
• WebDriver uses the program local similarity to robotization without utilizing any fringe element.

Highlights of WebDriver:-

1) "Interface WebDriver", which speaks to a glorified web program utilized for testing. Three classifications of strategies in this class.
• Control to program
• WebElements choice
• Debugging

2) We talked about above about dialect ties with programs and it is only a thin wrapper which is presented for us to compose code according to our necessities. This leads WebDriver to help "Numerous Languages" and also "Different Support Browsers" which implies that if any API bolsters various dialects then this consequently prompts "Various Platforms".

• Various Languages Binding SUPPORT
• Various Browsers SUPPORT
• Various Platforms SUPPORT

Speed contrast amongst RC and WebDriver:-

WebDriver coordinated correspondence with "Application under Test" makes it quicker than Remote Control as RC makes one more interface between interchanges which is RC Server makes it loves Client Server Communication.

WebDriver Existence in bundle org.openqa.selenium
org.openqa.selenium: The worldwide bundle of Selenium which we import in our program each time when it is expected to utilize WebDriver.

WebDriver Interface:-

How about we see what all WebDriver contains, for instance: – What is "FirefoxDriver": is a WebDriver which is utilized to associate with WebApps. In this way, this implies every one of the drivers ought to have every one of the usage which are contracted in the WebDriver interfaces and every one of the Drivers can be called as WebDriver.

Features:-

• WebDriver: One of the most center part from Selenium
• WebDriver: With immense highlights where driver covers every one of the highlights and properties of travelers
• WebDriver: Gives us the chance to compose once and execute on various stages
• WebDriver: Provides speed to Selenium design where correspondence with Application under Test turns out to be quicker
• WebDriver: Despite of taking a shot at any dialect or condition you require not to get the hang of anything new it is simply snatch the learning and begin creating comes about
• WebDriver: Gives chance to investigate something from center and can contribute starting with no outside help till end in Automation process
• WebDriver: Introduce AndroidDriver and IPhoneDriver to investigate Mobile world
