Automation Testing – Selenium Testing Tool Components (Part-2)

To overcome the issue and disadvantages of Selenium IDE, we have another segment of Selenium: Selenium RC. Selenium RC is the propelled rendition of Selenium IDE, which enables you to execute the experiments or test contents in different programs.

Selenium RC:-

Selenium RC is otherwise called Selenium Remote Control. As the beginning rendition of Selenium, it doesn't have any GUI interface; rather, it contains libraries or APIs which comprise of different classes, strategies, and interfaces which are utilized with different programming dialects like C#, Java, PHP, and Perl. It depends on protest situated programming standards.

Not at all like Selenium IDE, can the execution of experiments be executed just in the Firefox program. Selenium RC is the propelled rendition of Selenium IDE, which enables you to execute the experiments or test contents in different programs like Chrome, Firefox, IE, Safari, and Opera. Selenium RC underpins dialect freedom, which implies we can coordinate Selenium RC with any of the above dialects like C#, Java, and PHP. It likewise underpins stage freedom which implies the contents/code composed utilizing C#/Java can be executed in different stages like Windows OS, Mac OS, and Linux.

Some different highlights of Selenium RC:

• It is additionally founded on JavaScript. It doesn't have a Record/Playback include.
• It doesn't bolster versatile testing like iPhone or Android.
• It depends on a customer/server engineering, which implies at whatever point we need to execute the experiments/test contents, we have to begin the server physically.
• It underpins parallel execution of experiments and remote execution with the assistance of Selenium Grid.
• It underpins execution with non concurrent JavaScript-and XML-(AJAX) based applications also.

At whatever point we need to execute test cases, the Selenium server goes about as an arbiter/server which ought to be begun physically. At whatever point- selenium training in Bangalore we build up a structure utilizing the above programming dialects, this code is sent to Selenium Server, which goes about as a go between/server which thus changes over the code to JavaScript and sends it to the program. As the program comprehends JavaScript, the program executes the given experiments and returns the outcome back to the server or Selenium Server, and this server restores the outcome to the customer.

The downside of Selenium RC is that at whatever point we need to execute test cases, we have to begin the server or Selenium server physically. The code doesn't collaborate specifically with the program; the middle person is required. To defeat this issue, we have another form of Selenium: Selenium Webdriver.

Selenium Webdriver:-

To beat the above issue with Selenium RC, Webdriver was produced. Webdriver is a mix of Selenium RC and Webdriver. Selenium Webdriver doesn't require beginning the server/Selenium server to execute test cases.

It bolsters programming dialects like C#, Java, PHP, Perl, and Python and different stages to execute test cases, similar to Windows OS, Mac OS, and Linux. It underpins parallel and in addition remote execution.

Not at all like Selenium RC which requires Selenium Server as an arbiter to begin for the execution of experiments, Selenium Webdriver doesn't have to begin the server, which collaborates straightforwardly with the internet browser to execute the experiments.

It's a library/API which comprises of different strategies/classes/interfaces to use with different programming dialects like C#, Java, or Python.

Every program has its own drivers:

• To execute an experiment in Chrome, we have Chromedriver.
• To execute an experiment in Firefox, we have Geckodriver.
• To execute an experiment in Safari, we have Safaridriver.
• To execute an experiment in Internet Explorer, we have IEdriver.
• To execute an experiment in Opera, we have Operadriver.

It is an apparatus which is utilized for the execution of parallel and additionally remote execution by utilizing Selenium RC or Selenium Webdriver. For the execution of experiments in remote machines associated over LAN systems, we have to arrange a center and hub. selenium training in Marathahalli - The center point goes about as an arbiter or like a server and different hubs are arranged to a center.

On the off chance that we need to execute the experiments, say 6 distinctive experiments with 3 unique hubs associated with a center point, at that point the center's duty is to disperse the six diverse experiments among 3 unique hubs which are associated with a center.
