The Range of the Most Basic Test Data

Often there are cases when developers resort to the software testing company with a project for which there is no test data. Each tester must be able to create such data by his own.

Test data are very important for a variety of testing services – mobile testing[1], web site testing and desktop testing[2]. Even if the original package of the project already contains some test data, for example in the form of test cases – this is not a sign to stop – some customers encourage the testers’ initiatives to create additional test data as it can help to test the system on a more thorough level.

The main purpose of the test data is to develop the most complete cases to test the system and to reduce a variety of costs.

The Most Common Data for Software Testing:

• The complete absence of data – the tester does not have to enter any data to check how the system reacts, whether there are appropriate error messages or requests to enter data in the required fields.
• Valid data – most often during the functional testing of a web site or an online resource the authorization stage may be present – to ensure that the end user will be able to log in without a problem, the tester should try to enter the correct data.
• Invalid data – the special or inappropriate characters that in normal system operation should call messages about erroneous data.
• Illegal data – for example, entering of invalid domain names or an attempt to use another’s data (the latter should be checked also during the security testing).
• Data set for performance testing, load testing and stress testing[3]: This data set should be large in volume.
• Data which are in a boundary range must also be checked (upper and lower range values should be considered).
