I think all of these tests can reuse the global test client instead of creating new ones.

Everywhere we catch BaseException, can you add a one line comment to explain it's intentional? Something like:
# Catch KeyboardInterrupt, CancelledError, etc. and cleanup.

Let's use delete_many() instead of drop() for better perf.

Better yet, we can use setUpClass/tearDownClass to insert/drop the collection only once.

There is no asynchronous setUpClass/tearDownClass equivalent in unittest sadly. We could create our own, something like this:
async def setup_class(self):
...
self.init_class = True
async def asyncSetup(self):
...
if not self.init_class:
await self.setup_class()

Oh right. Let's not do that because it worth be hard/impossible to do the tearDownClass part.

Here and below, use insert_many instead of insert_one in a for-loop for better perf.

We can remove connected from these tests for better perf. If we need to get the connection we can move this below the insert_one().
