Summary: Tempfile doesn't pass be_an_instance_of(Tempfile). Maybe becouse it use decorator

Initial Comment:
describe "My problem" do

  it "should pass be_an_instance_of for newly created Tempfile" do
    # create test object
    xml_tempfile = Tempfile.new "object.xml"
    xml_tempfile.close
    # this kind of test passed normally
    xml_tempfile.class.should eql(Tempfile)
    # this doesn't pass
    xml_tempfile.should be_an_instance_of(Tempfile)
  end
end

In ruby-debug I found, that in validation stage, object become instance of File. Maybe something unwrap Delegator in Tempfile?

It works - but you shouldn't have to switch the requires. I'd say its still a bug.

Check this out - if you require in this order:

require 'spec'
require 'tempfile'

Then your example fails. However, if you require in this order:

require 'tempfile'
require 'spec'

Then the example passes!
