ActionTimerclass functionality.Changes
ActionTimerExecutor.Teststargeting .NET 9.0ActionTimerExecutor.slnTest Coverage
The test suite includes 21 comprehensive tests covering all public methods and scenarios:
Core Functionality
Timer Execution
Exception Handling
Resource Management
Dispose()method to ensure proper cleanup without exceptionsTesting Approach
All tests use NSubstitute to mock the
ILogger<ActionTimer>dependency, ensuring tests are isolated and don't require external logging infrastructure. The tests use realistic timing scenarios with appropriate delays to verify the periodic timer behavior while keeping test execution time reasonable.Test Results
✅ All 21 tests passing
✅ Build successful
✅ No security vulnerabilities detected
The test suite provides a solid foundation for maintaining code quality and catching regressions as the project evolves.
