<string>:3: ResourceExhausted
The fix would be to wrap the instance.create call with some form of exponential back-off, e.g. using the backoff
import backoff
w_backoff = backoff .on_exception (backoff .expo , exceptions .ResourceExhausted )
...
def test_create_instance_with_processing_units (capsys ):
processing_units = 500
w_backoff (snippets .create_instance_with_processing_units )(LCI_INSTANCE_ID , processing_units )or the RetryException class from google-cloud-testutils.
