AsyncTestCasea/`~unittest.TestCase` subclass for testing `.IOLoop`-based
    asynchronous code.

    The unittest framework is synchronous, so the test must be
    complete by the time the test method returns. This means that
    asynchronous code cannot be used in quite the same way as usual
    and must be adapted to fit. To write your tests with coroutines,
    decorate your test methods with `tornado.testing.gen_test` instead
    of `tornado.gen.coroutine`.

    This class also provides the (deprecated) `stop()` and `wait()`
    methods for a more manual style of testing. The test method itself
    must call ``self.wait()``, and asynchronous callbacks should call
    ``self.stop()`` to signal completion.

    By default, a new `.IOLoop` is constructed for each test and is available
    as ``self.io_loop``.  If the code being tested requires a
    reused global `.IOLoop`, subclasses should override `get_new_ioloop` to return it,
    although this is deprecated as of Tornado 6.3.

    The `.IOLoop`'s ``start`` and ``stop`` methods should not be
    called directly.  Instead, use `self.stop <stop>` and `self.wait
    <wait>`.  Arguments passed to ``self.stop`` are returned from
    ``self.wait``.  It is possible to have multiple ``wait``/``stop``
    cycles in the same test.

    Example::

        # This test uses coroutine style.
        class MyTestCase(AsyncTestCase):
            @tornado.testing.gen_test
            def test_http_fetch(self):
                client = AsyncHTTPClient()
                response = yield client.fetch("http://www.tornadoweb.org")
                # Test contents of response
                self.assertIn("FriendFeed", response.body)

        # This test uses argument passing between self.stop and self.wait.
        class MyTestCase2(AsyncTestCase):
            def test_http_fetch(self):
                client = AsyncHTTPClient()
                client.fetch("http://www.tornadoweb.org/", self.stop)
                response = self.wait()
                # Test contents of response
                self.assertIn("FriendFeed", response.body)

        By default, a new `.IOLoop` is created for each test.
        Subclasses may override this method to return
        `.IOLoop.current()` if it is not appropriate to use a new
        `.IOLoop` in each tests (for example, if there are global
        singletons using the default `.IOLoop`) or if a per-test event
        loop is being provided by another system (such as
        ``pytest-asyncio``).

        Failure to decorate asynchronous test methods with ``@gen_test`` can lead to tests

        DeprecationWarning) became a part of the standard library in 3.11.

        Note that ``_callTestMethod`` is not documented as a public interface. However, it is
        present in all supported versions of Python (3.8+), and if it goes away in the future that's
        OK because we can just remove this override as noted above.

    Subclasses must override `get_app()`, which returns the
    `tornado.web.Application` (or other `.HTTPServer` callback) to be tested.
    Tests will typically use the provided ``self.http_client`` to fetch
    URLs from this server.

    Example, assuming the "Hello, world" example from the user guide is in
    ``hello.py``::

        import hello

        class TestHelloApp(AsyncHTTPTestCase):
            def get_app(self):
                return hello.make_app()

            def test_homepage(self):
                response = self.fetch('/')
                self.assertEqual(response.code, 200)
                self.assertEqual(response.body, 'Hello, world')

    That call to ``self.fetch()`` is equivalent to ::

        self.http_client.fetch(self.get_url('/'), self.stop)
        response = self.wait()

    which illustrates how AsyncTestCase can turn an asynchronous operation,
    like ``http_client.fetch()``, into a synchronous operation. If you need
    to do other asynchronous operations in tests, you'll probably need to use
    ``stop()`` and ``wait()`` yourself.

        The given path will be appended to the local server's host and
        port.  Any additional keyword arguments will be passed directly to
        `.AsyncHTTPClient.fetch` (and so could be used to pass
        ``method="POST"``, ``body="..."``, etc).

        If the path begins with http:// or https://, it will be treated as a
        full URL and will be fetched as-is.

        If ``raise_error`` is ``True``, a `tornado.httpclient.HTTPError` will
        be raised if the response code is not 200. This is the same behavior
        as the ``raise_error`` argument to `.AsyncHTTPClient.fetch`, but
        the default is ``False`` here (it's ``True`` in `.AsyncHTTPClient`)
        because tests often need to deal with non-200 response codes.

        .. versionchanged:: 5.0
           Added support for absolute URLs.

        .. versionchanged:: 5.1

           Added the ``raise_error`` argument.

        .. deprecated:: 5.1

           This method currently turns any exception into an
           `.HTTPResponse` with status code 599. In Tornado 6.0,
           errors other than `tornado.httpclient.HTTPError` will be
           passed through, and ``raise_error=False`` will only
           suppress errors that would be raised due to non-200
           response codes.

    ``@gen.coroutine`` cannot be used on tests because the `.IOLoop` is not
    already running.  ``@gen_test`` should be applied to test methods
    on subclasses of `AsyncTestCase`.

    Example::

        class MyTest(AsyncHTTPTestCase):
            @gen_test
            def test_something(self):
                response = yield self.http_client.fetch(self.get_url('/'))

    By default, ``@gen_test`` times out after 5 seconds. The timeout may be
    overridden globally with the ``ASYNC_TEST_TIMEOUT`` environment variable,
    or for each test with the ``timeout`` keyword argument::

        class MyTest(AsyncHTTPTestCase):
            @gen_test(timeout=10)
            def test_something_slow(self):
                response = yield self.http_client.fetch(self.get_url('/'))

    Note that ``@gen_test`` is incompatible with `AsyncTestCase.stop`,
    `AsyncTestCase.wait`, and `AsyncHTTPTestCase.fetch`. Use ``yield
    self.http_client.fetch(self.get_url())`` as shown above instead.

S)aA simple test runner.

    This test runner is essentially equivalent to `unittest.main` from
    the standard library, but adds support for Tornado-style option
    parsing and log formatting. It is *not* necessary to use this
    `main` function to run tests using `AsyncTestCase`; these tests
    are self-contained and can run with any test runner.

    The easiest way to run a test is via the command line::

        python -m tornado.testing tornado.test.web_test

    See the standard library ``unittest`` module for ways in which
    tests can be specified.

    Projects with many tests may wish to define a test script like
    ``tornado/test/runtests.py``.  This script should define a method
    ``all()`` which returns a test suite and then call
    `tornado.testing.main()`.  Note that even when a test script is
    used, the ``all()`` test suite may be overridden by naming a
    single test on the command line::

        # Runs all tests
        python -m tornado.test.runtests
        # Runs one test
        python -m tornado.test.runtests tornado.test.web_test

    Additional keyword arguments passed through to ``unittest.main()``.
    For example, use ``tornado.testing.main(verbosity=2)``
    to show many test details as they are run.
    See http://docs.python.org/library/unittest.html#unittest.main
    for full argument list.

    .. versionchanged:: 5.0

       This function produces no output of its own; only that produced
       by the `unittest` module (previously it would add a PASS or FAIL
       log message).
