Using Visual Studio macro names to launch external applications doesn't work?

Question

Using Visual Studio / C#, I've been debugging some nunit tests recently, and am now trying to make sure that if we branch the code that the unit tests don't stop working in debug mode.

I have this working by changing project properties to launch NUnit as an external program:

C:\Program Files\NUnit 2.4.8\bin\nunit-console.exe

..and then set my .nunit config:

D:\SomePath\branches\NewFeatureBranch\TestDSP.nunit

So now I'd like to make that path generic. I thought something like this should work:

$(SolutionDir)\$(ProjectName).nunit

...but NUnit exits before running the test. Those variables don't appear to get sent though as a quick console app tells me:

arg[0] = D:\Projects\Tools\ArgDebugger\Debug\ArgDebugger.exe
arg[1] = $(SolutionDir)\$(ProjectName).nunit

Is there another way I can feed that information?

Answer 1

Well when I build two console apps.

App2 is debugged with App1. In App1 System.IO.Directory.GetCurrentDirectory() gives

Solution\Project\Bin\Debug of App2.

Therefore putting *..\..\..\* into the Working Directory of App2 gives me

*Solution\* of App2. So you can then change the path to the .nunit file to be ./TestDSP.nunit
