TestPathParser [add child]

The PathParser is used by the .NET FitServer to parse the path passed to it from FitNesse. You can include a config file on the path, and .NET FitServer will use that config file during the test run.

Try just one path entry...
path parser fixture
path string assembly paths? config file path?
c:\path\to\assembly.dll c:\path\to\assembly.dll null

Now two...
path parser fixture
path string assembly paths? config file path?
c:\path\to\assembly.dll;c:\path\to\other\assembly.dll c:\path\to\assembly.dll,c:\path\to\other\assembly.dll null

Now one assembly and one config file
path parser fixture
path string assembly paths? config file path?
c:\path\to\assembly.dll;c:\path\to\assembly.config c:\path\to\assembly.dll c:\path\to\assembly.config
