NUnitConfiguration.MonoExePath returns wrong path

[Eberhard Beilharz]

NUnitConfiguration.MonoExePath returns 'nunit-console.exe' when run on Mono on Linux. It should return the path to the Mono executable instead, e.g. '/usr/local/bin/mono'.

This happens in NUnit 2.5.5

Any thoughts on how to get this path?

Probably the easiest would be to just return "mono" and let the OS find it. That would most likely find the same installation that NUnit is currently running with, which I think should be sufficient in most cases.

If we want/need the full path, then one possibility would be to run "which mono".

Great idea! Returning "mono" on Linux is TSTTCPW.

I changed the logic to try the following 3 strategies in order

1. If a well-known script or exe is on the path, use it

2. Try to find mono

3. Use "mono"

For step 1, the names sought are mono.bat, mono.cmd and mono.exe on Windows, otherwise mono and mono.exe

For step 2, Windows examines the registry, nothing implemented on other platforms
