Selenium Grid Basics | Selenium Automation Testing Course

Selenium Grid allows you run your tests on different machines against different browsers in parallel. That is, running multiple tests at the same time against different machines running different browsers and operating systems. Essentially, Selenium-Grid support distributed test execution. It allows for running your tests in a distributed test execution environment.

Selenium Automation Testing

Selenium is the Automation Tool which is mainly used to automate Web Applications & Mobile Applications.
One of the main reasons why Selenium Testing Framework is more popular is because it is the Open Source Software (Automation Tool).
So it servers for cost-effective automation testing.
Selenium support different scripting language like Java, Php, Perl, Python, Ruby & C#
Selenium provides support for integration of open source frameworks like TestNG, JUnit, NUnit and so on.

Features of Selenium

Using Selenium, one can run the Selenium Test Cases in Multiple browsers.
Selenium can be integrated with TestNG testing framework for testing the applications and for generating the reports.
Selenium can be used for Android, iPhone, Blackberry etc. based mobile application testing.

Why Selenium is Great to use?

Taking the other automation tools into consideration, Selenium has the capability to operate on almost every OS.
Selenium is an open source testing tool and hence it serves for cost-effective automation testing.
Selenium supports multiple languages such as Python, Pearl, Ruby, PHP, .NET (C#) and Java. You are required to be comfortable in just a single language in order to operate Selenium.
One highly beneficial feature of Selenium is that the language used for building the program is independent of the language that the web application or website is using. This implies that the test script can be developed in any of the languages that Selenium supports.
This testing tool supports a range of browsers like Opera, Safari, Chrome, IE 6, 7, 8 and Mozilla Firefox.
Selenium has a very dynamic developer community that is backed by Google.
So far as Selenium is concerned, we have a number of robust methods for location of elements such as CSS, Xpath, DOM, and so on.
With Selenium, it is convenient to implement frameworks that revolve around Object oriented programming like Keyword Driven, Data driven and Hybrid.
Selenium provides support for integration of open source frameworks like TestNG, JUnit, NUnit and so on.
With the use of Selenium, it is possible to execute simultaneous tests leveraging various browsers on various machines. This is turn cuts down the time for test execution when a large project is in progress.
