nUnit Test function which uses executable path to open a file

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 i开发者_如何学运维n the test?
• Is there any easier way to test this method?

Thanks!

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.

you should make your path relative.

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