Coverage Exclusions and MbUnit

Hi,

I can happily exclude coverage for the Unit tests we don't run as part of our build process using the MbUnit.Framework.FixtureCategoryAttribute. As we are using MbUnit to run our tests, the attribute to exclude tests is [FixtureCategory("NoAutomation")]. If we choose to clasify tests into other categories these would be excluded from the coverage which is not what we want. Is there a way to specify the exclusion of classes marked with the FixtureCategory of NoAutomation, rather than excluding all tests with a FixtureCategory attribute?

Thanks

Andrew
