Hi,  
  
The NUnit -\> CategoryMask property is not converting the specified variable to string. &nbsp;Instead it puts in the variable name literally in the NUnit parameter line. &nbsp;  
Thus it does not exclude categories (CategoryMaskType set to 'Exclude').  
  
e.g.  
%NUNIT\_EXCLUDE% = "PinkTests"  
[Then when running FB, in the console it looks like]&nbsp;Parameters: "\\MyApp.UnitTest.dll" /framework:net-4.0 /xml="C:\Develop\MyApp\_UnitTestOutput.xml" /Exclude:"%NUNIT\_EXCLUDE%"

  
FB: 7.0.0.3319  
Windows 7 Ent. Service Pack1  
NUnit 2.6.4  
  
  
Regards,  
Ly
