Because we want to have information about how testing of requirements is going on, we need to provide an execution context.
For this report, execution context considers:
Test project
Test plan
Platforms (if exist)
Requirement are defined at Test project level
Execution results are recorded for: test plan, platform (if any exists) and build.
A Test plan defines a subset of test cases present on Test project, and because Requirements are covered by one or more test cases, this means that test plan defines in indirect way a subset of requirements.
We are considering LATEST EXECUTION on ANY BUILD.
