Most types with @abstractmethod definitions have their methods validated in test_collections.py, for example:

1. https://github.com/python/cpython/blame/49f61068f49747164988ffc5a442d2a63874fc17/Lib/test/test_collections.py#L1896-L1897
2. https://github.com/python/cpython/blame/49f61068f49747164988ffc5a442d2a63874fc17/Lib/test/test_collections.py#L928

But, not these three:

1. Awaitable
2. Coroutine
3. ByteString

I will add missing test cases for it.
