Strange minitest error when using files in test

ruby-talk
1

This is quite systematic when a test use files.

For instance, I have a minitest/spec test with

Utils.compare_file(file_1, file_2).must_equal true

When the comparison gives true, no problem. When the comparison gives
false, minitest aborts with :

TypeError: superclass mismatch for class Tempfile.

I did not find how to file a bug. Sorry.

I am running ruby-1.9.3-p429. This is a minimal example :

  describe 'Test' do
    it 'should not raise but report a failure' do
      __FILE__.size.must_equal 0
    end
  end

I get

   TypeError: superclass mismatch for class Tempfile
   C:/Ruby193/lib/ruby/1.9.1/tempfile.rb:81:in `<top (required)>'
   C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:45:in
`require'
   C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:45:in
`require
