'Report whether or not this test suite was successful or not.
The behaviour of this method changed in L{pyunit} in Python 3.4 to
fail if there are any errors, failures, or unexpected successes.
Previous to 3.4, it was only if there were errors or failures. This
method implements the old behaviour for backwards compatibility reasons,
checking just for errors and failures.
