从VS2010迁移到VS2013后的代码覆盖问题

Question

Recently I migrated all my C# projects from VS2010 to VS2013. There were barely any code changes required but immediately after I checked in the projects, I noticed that CI started failing. On checking the issue, I realized that the coverage file generated after running unit tests was not being generated in the location specified in the .testsettings file. In the Test Results Names section of Test Settings in VS2010, I configured a user defined naming scheme and unchecked the Append date-time stamp checkbox. This would generate the coverage file in \\\\data.coverage. After migrating to VS2013, the coverage file is getting generated in a Test Settings folder which believe is the default location when the Default naming scheme is chosen.

On researching a bit, I found an MSDN post and a few other blogs posts suggesting doing away with the .testsettings file and adopting the new .runsettings file. The weird thing is Microsoft is recommending usage of the .runsettings file but don't seem to deliver a default one which I can build upon. In any case, I did create one based on the sample provided on the same MSDN post. It did work for me as far as creation of the coverage file is concerned but I again faced the same problem that it is getting generated in a Test Results folder. The bigger problem is that a sub-folder with some GUID type name is created into which the coverage file is dumped and it changes every time a test is run with code coverage ON.

I wonder if there's a way make my VS2010 settings work as expected in VS2013 or using the .runsettings file, can I provide the complete path where the coverage file should be created?

Go to Test->Test Settings->Select Test Settings File and select the .testsettings file associated with your test project. It's a hack but always works.
