Merge lp:~yellow/zope.testing/fix-tests into lp:~launchpad/zope.testing/3.9.4-fork

[Brad Crittenden]

Fix failing tests caused by bit rot and the most recent changes to include sys.stdout and sys.stderr in the subunit output.

The latter breakage was fixed by converting two subunit doctests to be unit tests instead. In addition to the morphing of the stdout and stderr streams that we are now doing, the doctest runner changes it too. That was one level too much to cleanly handle and using unit tests avoided the problem.

Updated to p15.

Wow! Great work. Nice changes to the tests, and thank you for cleaning up the world.

I have two comments: one each about the most predictably commentable things in the MP.

(1) For get_real_stdout and friend, would you feel better and be able to remove that apologetic comment if the code looked like this instead?

___stdout = ___stderr = None
def get_real_stdout():
    """The canonical right place to get __stdout__."""
    return ___stdout or sys.__stdout__
def get_real_stderr():
    """The canonical right place to get __stderr__."""
    return ___stderr or sys.__stderr__
def set_stdout(new):
    """Set __stdout__ so that you can clean things up later.
    Other code can get at the original value with get_real_stdout."""
    global ___stdout
    ___stdout = sys.__stdout__
    sys.__stdout__ = new
def set_stderr(new):
    """Set __stderr__ so that you can clean things up later.
    Other code can get at the original value with get_real_stderr."""
    global ___stderr
    ___stderr = sys.__stderr__
    sys.__stderr__ = new
def reset_stdout():
    global ___stdout
    result = sys.__stdout__
    sys.__stdout__ = ___stdout
    ___stdout = None
    return result
def reset_stderr():
    global ___stderr
    result = sys.__stderr__
    sys.__stderr__ = ___stderr
    ___stderr = None
    return result

Maybe you want those to mess with stdout and stderr too.

Then, in testrunner.options.get_options, instead of directly mucking with __stderr__...

                # If we are running in a subprocess then the test runner code will
                # use stderr as a communication channel back to the spawning
                # process so we shouldn't touch it.
                if '--resume-layer' not in sys.argv:
                    sys.__stderr__ = sys.stderr = StringIO()

...we say "zope.testing.testrunner.set_stderr(StringIO())"

Similarly, when we set __stdout__ in doctests, we use the functions above, and then reset them using the functions.

The advantage is that we are not doing anything at __init__ time, and everything seems a bit cleaner to me. What do you think?

(2) For the new XXX in src/zope/testing/testrunner/tests.py in which we disable the tests, please add a bug for the broken tests and mention the number. I think it's worth following the usual practice.

Thanks again!

Small clean up. Prevent the --require-unique warning unless -m is really used.

We tried that, and it doesn't work (or at least it doesn't work in the
case of the test that was causing the problem). The trouble is that if
we wait until call time to work out what get_real_stdout() is going to
return then we're relying on that happening before anything mucks
about with sys.__stdout__. Either way, we need to do _something_ at
init time to make this not fail in weird and wonderful ways
(particularly with anything that uses the doctest module, which pokes
something unholy onto sys.__stdout__).

Yes, I agree; I'll take care of that tomorrow if Brad doesn't do it first.

-Subunit Output
-==============
-
-Subunit is a streaming protocol for interchanging test results. More
-information can be found at https://launchpad.net/subunit.

-
-
-Basic output
-------------
-
-Subunit output is line-based, with a 'test:' line for the start of each test
-and a 'successful:' line for each successful test.
-
-Zope layer set up and tear down events are represented as tests tagged with
-'zope:layer'. This allows them to be distinguished from actual tests, provides
-a place for the layer timing information in the subunit stream and allows us
-to include error information if necessary.
-
-Once the layer is set up, all future tests are tagged with
-'zope:layer:LAYER_NAME'.

-Listing tests
--------------
-
-A subunit stream is a stream of test results, more or less, so the most
-natural way of listing tests in subunit is to simply emit successful test
-results without actually running the tests.
-
-Note that in this stream, we don't emit fake tests for the layer set up and
-tear down, because it simply doesn't happen.
-
-We also don't include the dependent layers in the stream (in this case Layer1
-and Layer12), since they are not provided to the reporter.
-
-    >>> sys.argv = (
-    ...     'test --layer 122 --list-tests --subunit -t TestNotMuch').split()
-    >>> testrunner.run_internal(defaults)

-    sampletests.test122.TestNotMuch.test_2
-    sampletests.test122.TestNotMuch.test_3
-    False
-
-
-Profiling tests
----------------
-
-Test suites often cover a lot of code, and the performance of test suites
-themselves is often a critical part of the development process. Thus, it's
-good to be able to profile a test run.
