Mocking file uploads in Rails 3.1 controller tests

Question

My controller accesses the tempfile attribute of an uploaded file and passes it to another mocked component. My test code has

  @file = mock(Object)         


        

Answer 1

I went around this way

upload_file = fixture_file_upload('files/stats_upload.csv', 'text/csv')
upload_file.stubs(:tempfile).returns(upload_file)
