Founded by Simon Stewart in 2006, Selenium WebDriver was the first cross stage testing system that could control the program from OS level. Rather than IDE, Selenium WebDriver gives a programming interface to make and execute the test case. Tests are composed with the end goal that, web components on website pages are distinguished and afterward activities are performed on those components.

Selenium WebDriver is an web automation testing structure which can test pages started on different internet browsers and different working frameworks. Fact is that, you have the opportunity to compose test contents in various programming dialects like: Java, Perl, Python, Ruby, C#, PHP and JavaScript. Do take note of that Mozilla Firefox is Selenium WebDriver's default program.

WebDriver was presented as a component of Selenium v2.0. Selenium v1 comprised of just IDE, RC and Grid. However, the significant achievement in the Selenium venture was when WebDriver was created and presented as a substitution in Selenium v2. Be that as it may, with the arrival of Selenium v3, RC has been deplored and moved to inheritance bundle. You can at present download and work with RC yet, don't anticipate any help for it.
The advantages of WebDriver over RC are:
• Support for all the more programming dialects, working framework and internet browsers
• Overcoming the impediments of Selenium 1 like record transfer, download, pop-ups & exchange boundary
• Simpler directions when contrasted with RC, and a superior API
• Support for Batch testing, Cross program testing and Data driven testing

Be that as it may, the disadvantage when contrasted with RC is that, the test reports can't be produced. RC creates nitty gritty reports. If you want to educate yourself more about how to use WebDrivers and make the most out of it, you should enroll yourself in Selenium Training in Bangalore available.

Disadvantages Of Selenium RC And WebDriver birth

The restrictions of Selenium RC in light of the fact that was the purpose behind the inevitable improvement of WebDriver. You may be astonished when I state that Selenium RC turned into a moment hit when it was propelled. That was on the grounds that it conquered a similar starting point arrangement issue which was a noteworthy issue while testing web applications with Selenium Core. In any case, do you know what a similar beginning strategy issue was?

Same birthplace approach was rules which uphold web application security model. As indicated by a similar starting point strategy, the internet browser will permit JavaScript codes to get to components on the page, if and just if both the JavaScript and website page being tried are facilitated from a similar area. Selenium Core being a JavaScript-based testing tools, was incapacitated for a similar reason that it couldn't test each site page.

Be that as it may, when Selenium RC came into the image, it free analyzers of a similar cause arrangement issue. In any case, how did RC do that? RC did that by utilizing another segment called Selenium RC server. Along these lines, RC is a device which is a mix of two segments: Selenium RC server and Selenium RC customer.

Selenium RC server is a HTTP intermediary server, intended to "trap" the program into trusting that Selenium Core and the web application being tried are from a similar area. Consequently, there is no preventing the JavaScript code from getting to and testing any site.

Despite the fact that Selenium RC was a noteworthy hit, it had its a lot of issues. The real one being time taken for executing tests. Since the Selenium RC server is the center man in the correspondence between the program and your Selenium directions, test executions are very tedious. Other than the time factor, RC's design is additionally somewhat confused.

This design includes first infusing Selenium Core into the internet browser. At that point Selenium Core will get the guidelines from RC server and convert it into a JavaScript order. This JavaScript code is in charge of getting to and testing the web components.

Elements of browser

You more oftenly heard the expression "browser components" on various occasions in Selenium, so what are these components and how testing occurs on these web components.

Components are the diverse parts that are available on site pages. The most widely recognized components we see while perusing are:
• Text boxes
• CTA Buttons
• Images
• Hyperlinks
• Radio buttons/Checkboxes
• Text territory/Error messages
• Drop down box/List box/Combo box
• Web Table/HTML Table
• Frame

Testing these components basically implies we need to check whether they are working fine and reacting the manner in which we need it to.
1. Whether we can send content or numbers to the content box
2. Can we recover content that has been passed to the content box, and so on.

Thus, tasks can be performed on every one of the components referenced before. However, simply after the components are situated on the website page, we can perform tasks and begin testing them.
