[New-bugs-announce] [issue39385] Add an assertNoLogs context manager to unittest TestCase

[Kit Yan Choi]

New submission from Kit Yan Choi <kit at kychoi.org>:

assertLogs is really useful (issue18937). Unfortunately it does not cover the use cases where one wants to ensure no logs are emitted.

Similar to assertLogs, we can have a context manager for asserting no logs, something like this?:

with assertNoLogs(logger, level):
    ...


If logs are unexpected found, the test would fail with the logs captured included in the error message.

Happy to submit a PR if there is interest.
