Summary

We now record the test that an exception occurred in. We put this
information to use by aggregating the count of failures in each
test. For each exception, the exception report now prints the total
number of tests having that exception and the test with the least
number of exceptions exhibiting that failure. The exception list
is now sorted by (total count, tests impacted, count of failures
in least failing test).

This allows us to:

  • Assess how widespread a failure is. Some exceptions occur a lot in a few tests. Others occur over many tests.
  • Easily run a test exhibiting an exception without having to find a failure in test output.
  • Find and fix low hanging fruit (e.g. exceptions that are the only failure in a test).

Here's an example of the new output:

199 (4 tests) /home/gps/src/hg/hgext/blackbox.py:191: %b requires a bytes-like object, or an object that implements bytes, not 'str' (test-devel-warnings.t - 1 total)
