Is there a way to find out the project path at compile time?

I want to create a unit test that tests if the configurartion in the default web.config (the one in the project folder). Mainly to reduce human error.

I cannot rely on assembly locations at runtime (for the test), so I need to know where the project folder is to access web.config there.

I need a ‘generic’ solution since I’d like to use the same (base) test code for multiple projects, and the physical location is different anyway for most development machines.

Thanks.

  1. If you want the Visual Studio project path, at compile time, you could use a Pre-Build Event (see the Project Properties dialog) to run a command line that will create a source file used in your project.

    The source file will contain some code, say a variable definition. Your testing code uses this variable. The value of the variable will come from VS; when it runs your Pre-Build Event command, it substitutes project properties for certain macros. The macro you want is probably ProjectDir.

    So in the end, you have something like this for your Pre-Build Event’s command:

    echo 'const char * PROJECT_PATH = '$(ProjectDir)';' > source.cpp

    Not sure what language you’re using, so adjust accordingly.
