nUnit Test function which uses executable path to open a file

Question

I have a function which opens up the help file for the app. The function takes 3 arguments :

ShowHelp(appPath, 1, @"heelp\help.doc")

• The first argument is the start path.
• The second argument is the no of levels up the start path.
• The third argument is the path of the help file after going up n levels from the start path.

To test this I created a Resources folder in my test project, added a doc into this folder and supplied the below:

controller.ShowHelp(Application.ExecutablePath, 1, @"Resources\h.doc");

However when I run this thru test driven.net , my executable path is coming back as :

"C:\Program Files\TestDriven.NET 2.0\ProcessInvocation.exe"

• How do I supply the path of my Test Project in the test?
• Is there any easier way to test this method?

Thanks!

Answer 1

you should make your path relative.

in other words replace the application.executablepath with "/". See blog for more detail.

Answer 2

If you use

Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)

you should obtain the path for the library containing the tests, probably something like (..\bin\Debug), and then you can adapt the other parameters.
