NAME

       "Test::Future::AsyncAwait::Awaitable" - conformance tests for awaitable role API

SYNOPSIS

          use Test::More;
          use Test::Future::AsyncAwait::Awaitable;

          use My::Future::Subclass;

          test_awaitable "My subclass of Future",
             class => "My::Future::Subclass";

          done_testing;

DESCRIPTION

       This module provides a single test function, which runs a suite of subtests to check that
       a given class provides a useable implementation of the Future::AsyncAwait::Awaitable role.
       It runs tests that simulate various ways in which Future::AsyncAwait will try to use an
       instance of this class, to check that the implementation is valid.

FUNCTIONS

   test_awaitable
          test_awaitable( $title, %args )

       Runs the API conformance tests. $title is printed in the test description output so should
       be some human-friendly string.

       Takes the following named arguments:

       class => STRING
           Gives the name of the class. This is the class on which the "AWAIT_NEW_DONE" and
           "AWAIT_NEW_FAIL" methods will be invoked.

       new => CODE
           Optional. Gives a callback function to invoke to construct a new pending instance;
           used by the tests to create pending instances that would be passed into the "await"
           keyword. As this is not part of the API as such, the test code does not rely on being
           able to directly perform it via the API.

           This argument is optional; if not provided the tests will simply try to invoke the
           regular "new" constructor on the given class name. For most implementations this
           should be sufficient.

              $f = $new->()

       cancel => CODE
           Optional. Gives a callback function to invoke to cancel a pending instance, if the
           implementation provides cancellation semantics. If this callback is provided then an
           extra subtest suite is run to check the API around cancellation.

              $cancel->( $f )

       force => CODE
           Optional. Gives a callback function to invoke to wait for a promise to invoke its on-
           ready callbacks. Some future-like implementations will run these immediately when the
           future is marked as done or failed, and so this callback will not be required. Other
           implementations will defer these invocations, perhaps until the next tick of an event
           loop or similar. In the latter case, these implementations should provide a way for
           the test to wait for this to happen.

              $force->( $f )
