How to get Directory while running unit test

Usually you retrieve your solution directory (or project directory, depending on your solution structure) like this:

string solution_dir = Path.GetDirectoryName( Path.GetDirectoryName(
    TestContext.CurrentContext.TestDirectory ) );

This will give you the parent directory of the "TestResults" folder created by testing projects.

I would do it differently.

I suggest making that file part of the solution/project. Then right-click -> Properties -> Copy To Output = Copy Always.

That file will then be copied to whatever your output directory is (e.g. C:\Source\MyProject.Test\bin\Debug).

Edit: Copy To Output = Copy if Newer is the better option
