Function Documentation

def rosbridge_tools.tornado.testing.bind_unused_port ( )

Binds a server socket to an available port on localhost.

Returns a tuple (socket, port).

Definition at line 82 of file testing.py.

def rosbridge_tools.tornado.testing.gen_test	(	func = `None`,
		timeout = `None`
	)

Testing equivalent of ``@gen.coroutine``, to be applied to test methods.

``@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 gen.Task(self.fetch('/'))

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 gen.Task(self.fetch('/'))

.. versionadded:: 3.1
   The ``timeout`` argument and ``ASYNC_TEST_TIMEOUT`` environment
   variable.

.. versionchanged:: 4.0
   The wrapper now passes along ``*args, **kwargs`` so it can be used
   on functions with arguments.

def rosbridge_tools.tornado.testing.get_async_test_timeout ( )

Get the global timeout setting for async tests.

Returns a float, the timeout in seconds.

.. versionadded:: 3.1

Definition at line 92 of file testing.py.

def rosbridge_tools.tornado.testing.get_unused_port ( )

Returns a (hopefully) unused port number.

This function does not guarantee that the port it returns is available,
only that a series of get_unused_port calls in a single process return
distinct ports.

.. deprecated::
   Use bind_unused_port instead, which is guaranteed to find an unused port.

Definition at line 66 of file testing.py.

def rosbridge_tools.tornado.testing.main ( kwargs )

A 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.

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

    python -m tornado.testing tornado.test.stack_context_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.stack_context_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.
