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.
