Open APIs

Hello Team,

According to the TMF-653 Service Test API, a TestSpecification is typically associated with a ServiceSpecification, and on execution of each TestSpecification, a payload is generated for its results which can be retrieved via GET /serviceTest.

In my scenario, I have a ServiceSpecification that contains multiple TestSpecifications. From an execution perspective:

• One TestSpecification is modeled as the parent, and the others as its children.
• Only the parent TestSpecification is directly executed, which then triggers execution of the child TestSpecifications.
• Each TestSpecification has its own TestMeasures as defined by the TMF specification.
• After execution, I need to capture the results of both parent and child TestSpecifications.

My requirements are:

1. Single Payload for Aggregated Results
   Is there a recommended way in TMF-653 to represent the results of all related TestSpecifications within a single ServiceTest payload, instead of having multiple ServiceTest payloads (one per TestSpecification)?
2. Pass/Fail Metrics
   Each TestMeasure should have a pass/fail indicator, and there also needs to be an aggregated pass/fail outcome at the TestSpecification level (both parent and children).
   
• Does TMF-653 provide a standard way to represent this?
• Or is the recommended approach to extend the model (e.g., by introducing custom attributes for evaluation metrics)?

I would greatly appreciate any guidance on how to best model this scenario while staying compliant with TMF-653.

Thanks in advance
