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.

This makes sense, should assertNoWarns() be added too?

Thank you for looking into this.
Yes, I agree it makes sense to have assertNoWarns for the same reason.
