Questions on working with unittest.IsolatedAsyncioTestCase

[Mond Wan]

Hello all,

I would like to ask for helps on working with **unittest.IsolatedAsyncioTestCase**.

Q1: How to handle asyncio.CancelledError inside IsolatedAsyncioTestCase.

My test is hanging up if there are futures being cancelled some how. Is there a way for me to configure IsolatedAsyncioTestCase to throw any exceptions
to crash the main program such that I can read the line number?

I have also issue a post on stackoverflow, which include the codes I have written for explaining the question.

Q2: addAsyncCleanup vs asyncTearDown?

In the py3.8 manual, there is a method **addAsyncCleanup** for cleaning up stuff in async way. Why we need this instead of merging them altogether
into **asyncTearDown** at all?


Q3: Is it possible to configure a timeout mechanism for IsolatedAsyncioTestCase?

During my development, my tests always pending in somewhere. I cannot located them until I add print statements line by line. Is it possible to
configure the IsolatedAsyncioTestCase to crash the test, with line number, after specific period if such future is not resolved?


Thanks for your time
