New submission from Michael Newman <michael.b.new...@gmail.com>:
The attached example unit test file shows that assertDictContainsSubset cannot
handle error messages that need to show integer keys. Below is the output of
the test suite, where "test_mixed_keys_fail" has an error (code mistake), while
"test_text_keys_fail" produces a failure (result mistake) as expected.
