I have a question about how to add an addtional search path to NUnit testing. Although I know it's not best practice, I need it for some reason.
Let me description the directory structure first:
RootFolder
    unit-test.dll
    folder1
        a.dll
        folder1-1
            b.dll
    folder2
        c.dll
I have put my unit test dll in RootFolder, and under it there are many folders and also sub-folders. in each folder/sub folder there are some dlls which is referenced by my test dll.
now when i run my test dll with NUnit, i want the test dll to load the reference dll in sub-folder when needed.
i know it will work if i put all the reference dll in the root folder(same folder as test dll) but i don't want to break my directory structure.
