@andrewleap-optimizely (cc @pvcraven ) Any idea why with "self.assertRaises(OverflowError):" would not catch the Overflow error. But logs when Overflow exception occurs do show. It's all in the _run() function in config_manager().

I trigger Overflow error by passing a very large (overflowing) int to the update_interval for polling.

What confuses me is that the logs from that try block in the _run() funciton do show, but the Error is not raised. The assumption is that I mock the right thing.

Here I mock fetch_datafile get request that is inside PollingConfigManager:

project_config_manager = config_manager.PollingConfigManager(sdk_key=sdk_key, logger=mock_logger, update_interval=12345678912345)

However the error happens in the _run() function that is part of fetch_datafile(). Maybe error doesn't bubble up?
