Test data must be provided for every test case. One shouldn’t rely on standard test data; it is better to create the custom ones, besides preparation of them helps to assure sufficient test coverage and make the project more efficient.

Test Data Commonly Include:

  1. Valid test data; it is necessary to verify whether functions of the system are in compliance with the requirements and the system processes and stores the data as intended.
  2. Invalid test data; it is necessary to make sure that the software correctly processes invalid values, shows the relevant messages, notifying the user that the data are improper.
  3. Boundary test data values; defects connected with processing boundary values are frequent.
  4. Wrong data formats; it is wise to check how the system reacts on entering data in an inappropriate format, whether it shows the correct error messages.
  5. Absent data; it is a good practice to verify how the product handles entering a blank field in course of mobile application testing, desktop testing or web site testing.
