[MacRuby-devel] Issue with running unit tests when requiring rubygems

[Gabriel Ayuso]

I reinstalled the minitest and mocha gems to the following versions: minitest-2.0.2, mocha-0.9.12
The same issue I described before occurred once again.

Here's the code I ran on macirb and the result: 

require 'rubygems' 	#=> true
gem 'minitest'		#=> true
require 'test/unit'		#=> true
require 'mocha'		#=> true
class QuickTest < Test::Unit::TestCase
   def test_quick
     obj = mock('obj')
     obj.expects(:a).returns(true)
     assert( obj.a )
   end
 end 				# => nil
exit

Run options: --seed 43199

# Running tests:
