Selenium is a software tester launched by Apache Software company which lets us do software and website testing without any other programming language. It is  free of cost tester. Selenium has its own programming language named as Selenese. It gives competition to many latest testers. It is used in Linux, windows as well as mac. The Selenium allows developing test experiments in a firefox- based  graphical atmosphere.

For performing the test operation we have a designer script file .ds, formatting test script files i.e .Selenium and .scenario for testing the environment.

The Seven Basic Steps of Selenium Tests

1. Create a WebDriver instance.
2. Navigate to a Web page.
3. Locate an HTML element on the Web page.
4. Perform an action on an HTML element.
5. Anticipate the browser response to the action.
6. Run tests and record test results using a test framework.

Allowing the test function :

• Make a file separated by a comma and name it as com.csv.
• Choose the data file from the browser in the data tab.
• Put the userID and password in the next line and the third line and drag and drop the product field to the remaining lines.
