Test Data

Test data is a set of data that is specifically designed and generated to test a software application or system. It is used to validate the functionality, performance, and reliability of the software system. The test data can be input, output, or intermediate data, which is used to verify the correctness of the software system under various conditions. Test data can be of different types, including positive test data, negative test data, boundary test data, and error-generating test data. It is an essential component of the software testing process and helps in identifying defects and improving the quality of the software system.

Example of Test Data:

Suppose, we are testing a login page of an e-commerce website, and we need to check whether the website is accepting valid user credentials or not. In this case, the test data would be:

Username: john.doe@example.com
Password: MyPassword123
We can also create multiple sets of test data to test different scenarios like:

Username: john.doe@example.com, Password: InvalidPassword
Username: InvalidEmail, Password: MyPassword123
Username: john.doe@example.com, Password: (Empty Field)
By using these different sets of test data, we can cover various scenarios and identify any defects or issues in the login page.
