The Test Coverage view shows all tests associated with the Covered Issue (e.g. Story, requirement) and their respective status for the chosen analysis scope. In this view, you can create a new Test and associate it with the Covered Issue or just associate an already existing Test with it.
The status of the covered issue and of the linked Tests can be analyzed from multiple perspectives/scopes.
As an example, a user story aimed for version 3.0 may be analyzed from the point of view of the executions made for version 3.0 or for the ones made afterwards on version 4.0; it can eventually be analyzed by taking into account the Tests and Test Executions linked to some Test Plan. Of if you don't care with exact versions and just want to see the calculated statuses based on the latest runs, analysis by "Latest" can be used for that purpose. Another analysis dimension is the Test Environment; if chosen, then only executions made for that Test Environment are considered for the shown statuses.
In the version category, it is possible to see the Requirement Status for each of the project's versions.
In the test plan category, it is possible to see the Requirement Status for each of the Test Plans.
It's possible to see the status of each Test based on the Test Environment you chose in this option.
