What is Selenium software testing framework?

Selenium software testing framework is portable frame work that has been developed exclusively for the development of the web applications. It actually works as a record and play back tool for the guiding of the tests without having to learn about a TSL or test scripting language. 

The selenium software testing frame work comes with its own test domain – specific language known by the name of selenese which can be used for developing tests in a no. of prominent programming languages such as the following:

1. C#
2. Java
3. Groovy
4. PHP
5. Perl
6. Python
7. Ruby etc.

The tests thus developed can be executed against a number of modern web browsers. The selenium frame work can be deployed on the following three platforms:

1. Windows
2. Linux
3. Macintosh

- Selenium is one of the best open–source software that are available to us today. 

- It was released as an OSS under the license – apache 2.0 and so you won’t be charged for downloading and using it.

- The software got its name for a joke cracked by Jason in an email in which he mocked his competitor by saying that he can cure mercury poisoning with the help of supplements from selenium. 

- The other people who received this email began using this name and eventually the software was named so. 

- The selenium grid represents the latest side project which is known to provide a hub enable execution of the multiple selenium tests on a local and remote system and that too concurrently. 

- This is being done as an effort to minimize the time taken for execution. 

- The selenium provides you with a number of robust tools which one use for the rapid development of the automated tests for testing the web based applications. 

- Plus, it also comes with a number of rich features and functions which have been exclusively for designing the web applications. 

- The operations which are carried out by the selenium framework are highly flexible in nature and allow for the location of the UI elements with supported by a number of options. 

- Also, the selenium frame work accounts for comparing the actual and the expected test results. 

- Selenium’s key feature lies in the support it provides for the execution of one test on a number of browser platforms. 

- The selenium frame work is composed of three major tools each of which plays an important and unique role in the development of the tests for web applications:

1. Selenium IDE
2. Selenium remote control
3. Selenium grid

- There are number of ways in which functionality can be added to the selenium’s frame work to further customize the tests in order to suit one’s specific needs.

- This characteristic that makes the selenium frame work outstanding among the rest. 

- The RC support from the selenium assists the test writes in multiple programming by helping them develop any logic they require for automated testing by using their preferred language. 

- On the other hand, the user can add his own defined extensions via the selenium IDE for creation of additional customized commands. 

- The selenium RC code generated by the selenium IDE can be reconfigured easily which lets the testers generate code that would fit their testing frame work. 

- Also, since the selenium is open to all, all are free to submit their contributions for its enhancement and modification.
