This commit enhances unit test coverage for packages with the lowest
test coverage, focusing on previously untested methods and edge cases.
Changes:
- pkg/server/grpc: Increased coverage from 31.6% to 81.6%
- Added comprehensive tests for Clients.Run() method
- Added tests for GRPCServerOptions.Run() method
- Covered error handling, configuration validation, and context cancellation
- pkg/singleton/spoke: Enhanced test suite with additional edge cases
- Added method signature validation tests
- Added configuration setup and struct initialization tests
- Fixed race condition issues in existing tests
- pkg/server/grpc coverage improvements:
- Clients.Run(): 0% → 100% coverage
- GRPCServerOptions.Run(): 0% → 88.2% coverage
The new tests cover normal operation, error conditions, edge cases,
and defensive programming scenarios, significantly improving overall
code quality and test reliability.
