The correct answer is: A. users do not participate at this preliminary stage
Test data is data that is used to test a system or application. It is important to use good test data to ensure that the system or application is working correctly. Good test data should be:
- Comprehensive: It should cover all aspects of the system or application that are being tested.
- Valid: It should be accurate and realistic.
- Consistent: It should be the same for each test run.
- Reusable: It should be able to be used to test the system or application multiple times.
- Traceable: It should be possible to track the origin of the test data.
Users do not participate at this preliminary stage because it is important to test the system or application without any user input. This allows the tester to focus on the functionality of the system or application and to identify any bugs or errors.
The other options are all characteristics of good test data.
