The cleanup failures you’re experiencing are likely related to the management API port (9600) not being properly accessible or configuration changes being in progress during cleanup. I found the following relevant resources:
- CPT Test Lifecycle Documentation - explains how CPT automatically deletes runtime data between tests
- Remote Runtime Configuration - details on exposing management API port 9600 and enabling controlled clock
- CPT Best Practices for Testing Process Definitions - checklist for proper test setup including job worker stubbing
- Mock Job Workers Utilities - proper way to mock job workers to avoid test interference
- Forum Discussion on CPT Cleanup Issues - community discussion about similar cleanup problems
Does this help? If not, can anyone from the community jump in?
