PR Review: Allow skipping tests per-argument

Todo List:

  • Read repository guidelines and understand codebase
  • Analyze changed files for implementation details
  • Review code quality and best practices
  • Check for potential bugs or issues
  • Assess performance considerations
  • Evaluate security concerns
  • Analyze test coverage
  • Provide comprehensive review feedback

🔍 Review Summary

This PR successfully implements the ability to skip individual test arguments using the Skip property on ArgumentsAttribute. The implementation follows TUnit's dual-mode architecture requirement and properly handles both source-generated and reflection modes.

Strengths

  1. Dual-mode compliance: ✓ Correctly implements the feature in both ArgumentsAttribute (reflection mode) and source generator
  2. API consistency: ✓ Both generic and non-generic ArgumentsAttribute variants support the Skip property
  3. Proper integration: ✓ Uses existing SkippedTestInstance.Instance for consistency
  4. Event-driven design: ✓ Leverages ITestRegisteredEventReceiver for proper test lifecycle integration
  5. Public API snapshots: ✓ All snapshot files updated correctly to reflect API changes

📋 Implementation Analysis

ArgumentsAttribute.cs (TUnit.Core/Attributes/TestData/ArgumentsAttribute.cs:32-39, TUnit.Core/Attributes/TestData/ArgumentsAttribute.cs:55-64):

  • Clean implementation using OnTestRegistered event
  • Properly sets both SkipReason and ClassInstance for skipped tests
  • Consistent implementation across both generic and non-generic variants

TestBuilder.cs (TUnit.Engine/Building/TestBuilder.cs:329-343):

  • Correctly integrates skip logic into test building process
  • Maintains performance by checking skip reason early before instance creation

Test Coverage (TUnit.TestProject/SkippableArgumentTests.cs):

  • Good basic test coverage demonstrating the feature
  • Tests both skipped and non-skipped arguments in the same test method

🔧 Minor Suggestions

  1. Null check improvement: Consider more defensive null checking:

    // Current
    if(!string.IsNullOrEmpty(Skip))
    
    // Suggested 
    if (!string.IsNullOrWhiteSpace(Skip))
  2. Test coverage enhancement: The test file could benefit from additional edge cases:

    • Empty string skip reason
    • Multiple consecutive skipped arguments
    • All arguments skipped scenario
  3. Documentation: Consider adding XML documentation to the Skip property for better IntelliSense support.

🚀 Performance Assessment

  • Excellent: Early skip detection prevents unnecessary instance creation
  • Efficient: Reuses existing SkippedTestInstance.Instance singleton
  • Optimized: Skip logic integrated into discovery phase, not execution phase

🔒 Security Assessment

  • Safe: No security concerns identified
  • Input validation: Skip reasons are treated as display strings with no execution risk

🎯 Compliance with TUnit Guidelines

  • Dual-mode implementation: Both source-gen and reflection paths implemented
  • Snapshot tests: Public API snapshots properly updated
  • Performance first: Optimized for minimal overhead
  • Modern C# syntax: Clean, idiomatic code

📊 Overall Assessment

This is a well-implemented feature that:

  • Follows TUnit's architectural patterns
  • Maintains performance characteristics
  • Provides the expected functionality
  • Includes appropriate test coverage

The implementation quality is high and ready for merge. The minor suggestions above are optional improvements rather than required changes.

Recommendation: ✅ APPROVE
