How to exclude Projects with names ending in “.Test” from my code coverage analysis in VS2012 Unit Tests

There is a connection with the period issue as it was mentioned here.
If you change the exclude section to this

<ModulePath>.*tests.dll</ModulePath>
<ModulePath>.*Tests.dll</ModulePath>

or this

<ModulePath>.*\.tests\..*</ModulePath>
<ModulePath>.*\.Tests\..*</ModulePath>

it’ll work
