nCover + MSTest + CruiseControl = Zero Coverage

Question

Hi,

I use CruiseControl.net, MSTest 3.5 and nCover 1.5.8. I am new to nCover and want to integrate it in CruiseControl.

The problem is that I get a 0% coverage result but it should be 100%. My demo app calls just one method and in my mstest project this method is tested. in my cruiseControl server all works fine without ncover and i can see the mstest results (passes with ok)

now i want to through in nCover. in my cruiseConttrol server I call a nant script that does this (simplified):

<target name="nCover">
  <exec program="C:\Programme\NCover\ncover.console.exe" 
       workingdir="C:\temp" 
       commandline="//a CCTestApp //x coverage.xml C:\MSTest.exe /testcontainer:UnitTests.dll /resultsfile:mstestResult.trx /nologo" />
</target>

Running this in cruisecontrol seems to work and i can see the ncover result. but the result is 0% coverage

any ideas?

bye bembi

Answer 1

I got it!

If using MSTest you have to set the /noisolation flag for mstest in order to get it working! this flag prevents mstest from starting another thread which ncover can't handle.

Answer 2

You can also set the //coverall flag on NCover, which will allow it to handle process isolation under MSTest.
