Description

The nifi-system-tests module contains multiple integration tests for verifying behavior using minimal instances of NiFi.  The GitHub system-tests workflow fails on some occasions due to apparent timing issues when making requests or evaluating expected results. The polling approach and instance configuration properties should be evaluated for potential improvements to make the tests more reliable in environments with limited resources.
