Hi

I’m unable to run the tests for the mongo driver and mongomapper but  
I’m  
able to run all but 1 example, and that example doesn’t work on MRI  
either.  
The error from Test::Unit has something to do with shoulda and mocha in  
the  
same project from what I could find on the web.

So the good news I think is that mongomapper seems to work from the  
limited  
amount of tests I’ve done with it so far.

- C:\dev\mongo-ruby-driver  
(master) » ir -S rake test:ruby  
(in C:/dev/mongo-ruby-driver)  
C:/ironruby/bin/ir.exe -I"lib"  
“C:/ironruby/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake\_test\_loader.rb”  
“test/unit/collection\_test.rb” “test/unit/connection\_test.rb”  
“test/unit/cursor\_test.rb” “test/unit/db\_test.rb”

\*\*Notice: C extension not loaded. This is required for optimum MongoDB  
Ruby  
driver performance.  
You can install the extension as follows:  
gem install mongo\_ext

If you continue to receive this message after installing, make sure  
that  
the  
mongo\_ext gem is in your load path and that the mongo\_ext and mongo  
gems  
are of the same version.
