Unit test by skipping library functions for code coverage

Question

I am trying to create a unit test in MS Test for a CMS application, wherein I have minority number of function that I wrote in my solution, the majority of the functions came along with CMS framework.

Issue:

When I take the code coverage it shows less than 1 percentage. But this coverage is meaningless.

Question:

How can I find coverage for only the functions that I wrote skipping the library functions that came along with cms framework?

You can configure which assemblies your code coverage should look for.

You need to edit .runsettings file for the Unit tests and add this

<ModulePaths>  
  <Exclude>  
   <ModulePath>Name of the dll goes here</ModulePath>  
   <!-- Add more ModulePath nodes here. -->  
  </Exclude>  
</ModulePaths>

If this works to exclude the CMS calls purely via Configuration, it's better than my answer +1 – Jeremy Thompson Sep 25 '17 at 07:02
yea, I hope, need to check – SmartestVEGA Sep 25 '17 at 07:02
There is a catch here, the unit is entire DLL, what if I have written functions inside that DLL? how to ignore the function which I have not written in that DLL? – SmartestVEGA Sep 25 '17 at 09:02
I think that Adding only assemblies which are needed to be unit tested in the ModulePath and then again filtering by applying ExcludeFromCodeCoverage attribute will help you as said by @JeremyThompson. – Ipsit Gaur Sep 25 '17 at 09:11
ExcludeFromCodeCoverage need to be applied in CMS framework library code, but I don't want to alter framework code, is there anything like IncludeinCodeCoverage where I can give in my code? – SmartestVEGA Sep 25 '17 at 09:19

Will this work for you Including only specific functions ^Fabrikam\..* .*\.EqualTo\(.* .*\.UnitTest\..* – Ipsit Gaur Sep 25 '17 at 09:24
Let me try that looks promising – SmartestVEGA Sep 25 '17 at 09:33
Did that work for you, if yes can you mark it as the answer? – Ipsit Gaur Sep 28 '17 at 05:35

There is a ExcludeFromCodeCoverage attribute you can use.

You may need to isolate the CMS calls to a class or methods that you can decorate with this Attribute to skip the library functions.

I am not sure, I can alter the framework code, I need to keep the framework code as it is and get the coverage excluding the framework code. – SmartestVEGA Sep 25 '17 at 07:01

The idea was a middle layer that excluded the CMS layer. @Ipsit answer looks better for what you want. – Jeremy Thompson Sep 25 '17 at 07:03
