It is sometimes useful to check for the log messages emitted by some piece of code (especially a library). Would it be a good idea to add a dedicated assertion method for that? I would propose the following API:


with self.assertLogging("logger.name", level="WARN") as cm:
    ...

The `cm` context manager could give access to all the log records and formatted output lines for the given logger name (and children) and at least the given logging level. I have something like that here, except not with a dedicated assertion method:
