[Mono-dev] Reflection Emit issues

[Gert Driesen]

Hi Ayende,

 

I tried the tests myself (with SVN head), and did not even succeed in
running the complete test suite:

 

"no implementation for interface method
Rhino.Mocks.Interfaces.IMockedObject::g

_ProxyHash() in class .genericClass`1Proxy79e618bfe6044bb9bb680503b32a2e36

 

This application has requested the Runtime to terminate it in an unusual
way.

Please contact the application's support team for more information."

 

It would be great if you could create smaller test cases, and submit a bug
reports for these issues.

 

A good place to start would be running the unit tests of Castle on Mono, and
once these pass move on to the Rhino tests.

 

Gert

Hi guys,
I have just attempted to run the Rhino Mocks test suite on Mono (Win32).
The result is about 300 failing tests. The root cause seems to be
differences in Reflection.Emit behavior.
Rhino Mocks is using Castle Dynamic Proxy 2 to generate proxies, and all
those tests are running on the Microsoft .NET implementation successfully. 

How to reproduce:
1/ Get the source from
https://rhino-tools.svn.sourceforge.net/svnroot/rhino-tools
2/ Build rhino-mocks (xbuild default.build )
3/ rhino-tools\rhino-mocks\Rhino.Mocks.Tests\bin\debug>"c:\Program
Files\Mono-1.2.3.1\bin\mono" MbUnit.GUI.exe

The result of one of the failing tests:

1)
Rhino.Mocks.Tests.FieldsProblem.PresenterBaseTestFixture.SetUp.TestEventInit
