Pull Request Overview
This PR significantly improves test coverage for the agents-common module by adding comprehensive unit tests across multiple packages. AI-assisted test generation (using Cursor AI) was employed, with manual review applied to all generated code. The changes focus on previously untested or under-tested code paths, achieving substantial coverage improvements across seven packages.
Key Changes:
- Added unit tests for client-related functionality (org.apache.ranger.plugin.client, org.apache.ranger.admin.client)
- Enhanced test coverage for authorization utilities and configuration (org.apache.ranger.authorization.*)
- Implemented comprehensive tests for audit handler components (org.apache.ranger.plugin.audit)
- Added Hadoop security-related test cases (org.apache.hadoop.security)
- Integrated Mockito test dependencies (mockito-inline and mockito-junit-jupiter)
- Updated existing StringUtil and JsonUtils tests to use JUnit Jupiter assertions
