[Mono-dev] Mono and NMock2 - failing to run NMock2 with mono svn

[Mads Bondo Dydensborg]

Hi there

I have observed that my nmock2 tests have started to fail with the version of 
mono I compile from svn. Running this command:

$ echo $MONO_PATH
/home/madsdyd/xintegra/trunk/Components/Bin/:/home/madsdyd/xintegra/trunk/Lib/NUnit:/home/madsdyd/xintegra/trunk/Lib/NMock:/home/madsdyd/xintegra/trunk/Lib/NLog/Mono
$ which mono
/usr/local/mono-svn/bin/mono
 $ mono --version
Mono JIT compiler version 1.2.4 (/trunk/ r81006)

        Disabled:      none
$ 
mono --debug /home/madsdyd/xintegra/trunk/Lib/NUnit/nunit-console.exe ../Bin/Debug/DBC.ORM.dll

fails with:

Failures:
1) SQLBuilderTest.SelectOrAndSQL : System.InvalidCastException : Cannot cast 
from source type to destination type.
  at SQLBuilderTest.SetUp () [0x00035] 
in /home/madsdyd/xintegra/trunk/Components/DBC.ORM/UnitTest/SQLBuilderTest.cs:90
  at <0x00000> <unknown method>

System.Globalization.CultureInfo culture) [0x00056] 
in /home/compile/Compile/Mono/mcs/class/corlib/System.Reflection/MonoMethod.cs:146

The offending statement is:

      mockProvider = mocks.NewMock<IProvider>();

AFAICT the assignment does not matter, the failure is somewhere in NewMock(?)

However, running with stable mono:

$ mono --version
Mono JIT compiler version 1.2.3.1, (C) 2002-2006 Novell, Inc and Contributors. 
www.mono-project.com
        TLS:           __thread
        GC:            Included Boehm (with typed GC)
        SIGSEGV:       normal
        Architecture:  x86
        Disabled:      none

The test passes as expected - with no fails (neither from NUnit or Mono). In 
both cases, the compilation of my source tree has been using the svn version 
of mono/gmcs.

So, two questions:

a) Is anyone else experiencing this issue?
b) Any advise on resolving it?

Thanks in advance, and regards,

Mads
