             Summary: [C++/Python] Provide assertion helpers in the style of pandas.testing.assert_frame_equal
                 Key: ARROW-2647
                 URL: https://issues.apache.org/jira/browse/ARROW-2647
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++, Python
            Reporter: Uwe L. Korn


Pandas provides helper functions for writing tests based on its data structures that output an explanative error message on assertion failures. In constrast, Arrow at the moment only supports boolean equals comparisons. We should add helper functions that also give a very detailed response on where the comparison failed.
