Issues and Observations

Issue 1: Service Startup Time

Observation: Services take 60-90 seconds to fully initialize
Impact: Low - Expected behavior
Resolution: Wait period included in test scripts

Issue 2: Some Services Not Running

Observation: Not all services were running during test execution
Impact: Medium - Partial test coverage
Resolution: Code verified for all services, runtime tests can be completed when all services are running

Issue 3: Response Body in Some Cases

Observation: Some services return empty response body for 404
Impact: Low - Status code is correct
Resolution: Exception handler is working, may need response configuration
