Description

chore: Add Unit Tests for the PolicyServiceImpl Class

This PR introduces comprehensive unit tests for the PolicyServiceImpl class in the Traceability backend. The class contains business logic for managing policies and interacts with PolicyRepository and EdcNotificationContractService.

The new tests improve code reliability and ensure correct interaction with the dependent components.

• Covered all public methods:
  • getIrsPolicies() (raw data map)
  • getPolicies() (flat list of PolicyResponse)
  • getPolicy(String id) (success + PolicyNotFoundException)
  • createPolicy(RegisterPolicyRequest) (creates policy, updates EDC)
  • updatePolicy(UpdatePolicyRequest) (updates policy, updates EDC)
  • deletePolicy(String id) (deletes policy, updates EDC)
• Included tests for:
  • Success (happy path)
  • Error and edge cases (e.g. null, empty values, missing entries)
  • Interaction with dependencies (Mockito verify)
• Ensured test coverage > 90%

Notes

• No changes to business logic
