Test case and sessions management

1. Definition of all the tests needed to verify its behavior against its requirements (this is clear and easy)
   
   
2. Having its estimated work summarized into a "parent object"
   It is the test session
3. List all the test cases into a test plan - is it the test session here?
   Yes, It is the test session
4. Have a log of all test sessions launch over the test plan - I have here a big confusion in between the concept of test session and test plan for ProjeQtOr.
   It is the "test case run" on the test session
5. Have a way (e.g. with the automated integration files) to import the test results from the non-regression tool manager (e.g. Jenkins).
   You can import "TestCaseRun" through import or through API
6. Have a summary report (could use the API if needed) that indicates by week the evolution of the test sessions (which by the way are at least done daily, somethimes more).
   You'll have to build the "history", as I don't think we have such report
   1. The report would ideally have the number of tests passes, failed, blocked, non executed. All stacked to obtain also the evolution of the number of test cases.
      You'll find it on test session and several reports, but without "history"

Is there a part of the documentation giving an how-to or example of using the test cases, test sessions and test runs?

Finally I would like to add some information on the test run like the revision of the version control used for the run, or a seed (we are using randomized tests).
Is it possible to do that? I can't find it on the customization plug-in.
