Upgrading Team Foundation Server 2008 Reports to 2010, Part III
This is likely to be my final post on upgrading reports for Team Foundation Server 2010, and reflects one last change we made to the cube schema from the Release Candidate to the final version. This last change was to improve the performance of cube processing, and in particular, processing the Test Result dimension. We were able to significantly improve performance by removing the Area and Iteration Hierarchy attributes from the Test Result dimension.
So if you have any reports that use these hierarchies in the Test Result dimension, you’ll need to update your reports.
Sunder Raman has provided a higher-level overview of this change:
Area HierarchyYou’ll want to use the Area Hierarchy from the Test Case dimension. The idea is that the test case defines the area that is being tested, so this is the appropriate test result to use. Your other option would be to use the Area Hierarchy from the Test Plan dimension. However, we don’t recommend this because test plans can and often do cover multiple areas.
One side effect of this change is that you’ll now see the area for some test results listed as Unknown. This means they don’t have any area, which will be the case when you publish unit test results that aren’t connected to a Test Case. Previously these test results appeared in the root area path for your Team Project, so it’s a minor change. But now you can at least tell which test results were explicitly connected to an area as a result of being run via a Test Case.
