  1 failed and 8 succeeded in 0.002127538 seconds]: [Detailed test failure that shows different formatting than what was expected in the tests.]

Issue: Ruby changed debug formatting, which some gems relied upon in their tests. This is one of such cases.
Resolution: Change the format in tests to be consistent with the expectation of Ruby.
