Test your knowledge: asynchronous unittest

Review

1. Which built-in test case class is designed to run coroutine test methods?

   `IsolatedAsyncioTestCase` accepts coroutine test functions and manages their async execution.
2. How should a test obtain the return value of `async def load()`?

   Await the operation inside the async test method, then assert on the completed result.
3. Where should an awaited call that is expected to raise `ValueError` go?

   An awaited coroutine exception can be tested by placing the await inside `assertRaises`.
4. What is the documented ordering of the setup and teardown methods around an async test?

   The documented order runs `setUp()` before `asyncSetUp()` and `asyncTearDown()` before `tearDown()`.
5. Which API registers a coroutine for async cleanup after the test?

   `addAsyncCleanup()` registers an asynchronous cleanup function; the framework executes it as cleanup.
6. Which AsyncMock assertion proves that a dependency was awaited once with `"item-4"`?

   `assert_awaited_once_with()` verifies the awaited call and its arguments.
