Define tests for a particular service type, product model, or inventory to troubleshoot the service-related problems.

Test definition includes characteristics, relationships, test measures definitions, measure consequences, and threshold rules. These entities enable the system to trigger relevant tests for the service problem that help to identify the
root-cause of the problem. You can define these entities for each test based on your requirements.

A service test definition outlines the parameters to be configured and the metrics to be measured for a given service test. These parameters are defined in the test definition. They can be set during execution to run the tests that
measures the service problem effectively. This structured approach confirms that the test is done correctly and collects all the data needed to identify the problem of the service.
