.net - Visual Studio Test Explorer error: An exception occurred while initializing the database. See the InnerException for details -

-

i using visual studio 2013. have 2 branches.

test explorer works fine on branch not on branch b. following error in test output window:

------ discover test started ------ **an exception occurred while initializing database. see innerexception details.** ========== discover test finished: 4530 found (0:00:07.34) ==========

as can see, seems discover tests not populate test explorer window.

what database use? there project specific cache remove?

i use resharper tried turning unit test engine off did not help. have done rebuilds cleans etc. no avail.

  3. close visual studio 2013
  4. open task manager , end sql server windows nt - 64 bit processes
  5. use windows explorer navigate location of solution , find folder called testresults
  6. delete folders , files folder including tests.mdf files
