        =========
        asynctest
        =========
        
        The package asynctest is built on top of the standard unittest module and
        cuts down boilerplate code when testing libraries for asyncio.
        
        Currently, asynctest targets the "selector" model, hence, some features
        will not (yet?) work with Windows' proactor.

        Features
        --------
        
        TestCases
        ~~~~~~~~~
        
          - Initialize and close a loop created for each test (it can be
            configurated), if the loop uses a selector, it will be updated with
            a TestSelector object wrapping the original selector (see below),
        
          - if the test function is a coroutine function or returns a coroutine, it
            will run on the loop,
        
          - TestCase.setUp() and TestCase.tearDown() can be coroutine functions,
        
          - control post-test checks with `@fail_on`, for instance, the test fail if
            the loop didn't run, some optional checks can be activated,
        
          - ClockedTestCase allows to control the loop clock and run timed events
            without waiting the wall clock.
        
        Mock and CoroutineMock
        ~~~~~~~~~~~~~~~~~~~~~~
        
          - CoroutineMock is a new Mock class which mocks a coroutine function, and
            returns a coroutine when called,
        
          - MagicMock supports asynchronous context managers and asynchronous
            iterators,
        
          - NonCallableMock, Mock and CoroutineMock can return CoroutineMock objects
            when its attributes are get if there is a matching attribute in the spec
            (or spec_set) object which is a coroutine function,
        
          - patch(), patch.object(), patch.multiple() return a MagickMock or
            CoroutineMock object by default, according to the patched target,
        
          - patch(), patch.object(), patch.multiple() handle generators and coroutines
            and their behavior can be controled when the generator or coroutine pauses,
        
          - all the patch() methods can decorate coroutine functions,
        
          - mock_open() returns a MagickMock object by default.
        
          - return_once() can be used with Mock.side_effect to return a value only
            once when a mock is called.
        
        Selectors
        ~~~~~~~~~
        
        The module asynctest.selector provides classes to mock objects performing IO
        (files, sockets, etc).
        
          - FileMock is a special type of mock which represents a file.
            FileMock.fileno() returns a special value which allows to identify uniquely
            the mock,
        
          - SocketMock is a special type of FileMock which uses socket.socket as spec,
        
          - TestSelector is a custom selector able to wrap a real selector
            implementation and deal with FileMock objects, it can replace a selector
            loop by calling `loop._selector = TestSelector(loop._selector)`, and will
            intercept mock so they don't get registered to the actual selector.
        
          - set_read_ready() and set_write_ready() to force read and write event
            callbacks to be scheduled on the loop, as if the selector scheduled them.
        
        Helpers
        ~~~~~~~
        
          - the coroutine exhaust_callbacks(loop) returns once all the callbacks which
            should be called immediately are executed, which is useful when the test
            author needs to assert things which are not yet executed by the loop.
        
        Roadmap
        -------
        
        I hope I will find time to develop and release the following features:
        
        - set of warnings against common mistakes
        - proactor support
        
        Tests
        -----
        
        asynctest is unit tested. You can run asynctest test suite with this command::
        
        $ PYTHONPATH=. python -m unittest test
