I was wondering if dotCover has an ability (with resharper) to filter out those tests that were affected by some changes in code. I mean to reproduce the VS2010 feature - Test -> Run all impacted tests (http://blogs.msdn.com/b/phuene/archive/2009/12/07/test-impact-analysis-in-visual-studio-2010.aspx)
This feature is in our nearest plans.
We already have per-test coverage info and are able to identify list of tests which cover particular part of the code.
So ability to run all impacted tests is the next step in this direction.
