How to make VS ignore code coverage for Test dll

Question

Currently, when I run code coverage analysis the reported coverage is 90%. The thing is that the other 10% is the code for the actual test!

How can i make VS ignore that test code and only take into account the actual code?

Answer 1

You can add a runsettings file in your project.

In that file you can mention DLL names which needs to be excluded from code coverage:

<ModulePaths>
  <Include>
    <!-- Include all loaded .dll assemblies (but not .exe assemblies): -->
    <ModulePath>.*\.dll$</ModulePath>
  </Include>
  <Exclude>
    <!-- But exclude some assemblies: -->
    <ModulePath>.*\\Fabrikam\.MyTests1\.dll$</ModulePath>
    <!-- Exclude all file paths that contain "Temp": -->
    <ModulePath>.*Temp.*</ModulePath>
  </Exclude>
</ModulePaths>

This page and This page should give you more details on how to add and how to configure runsettings file for unit tests.

Hope this helps you.
