Claude finished @thomhurst's task —— View job PR Review: Cross-type equality assertions with IEquatableI've completed a thorough review of this PR that adds support for cross-type equality assertions with IEquatable for structs. Here's my comprehensive feedback: ✅ Overall Assessment: EXCELLENTThis is a well-implemented feature that addresses a legitimate user need (issue #2972) with careful attention to code quality, performance, and maintainability. Code Quality & Best Practices ⭐⭐⭐⭐⭐Strengths:
Code Organization:// TUnit.Assertions/Conditions/EquatableAssertion.cs:166-174
public static EquatableAssertion<TActual, TExpected> IsEqualTo<TActual, TExpected>(
this IAssertionSource<TActual> source,
TExpected expected,
[CallerArgumentExpression(nameof(expected))] string? expression = null)
where TActual : struct, IEquatable<TExpected>Perfect use of generic constraints and caller expression attributes. Performance Considerations ⭐⭐⭐⭐⭐Excellent Performance Design:
// TUnit.Assertions/Conditions/EquatableAssertion.cs:39
if (value.Equals(_expected)) // Direct IEquatable call - no boxing!Security & Safety ⭐⭐⭐⭐⭐Robust Error Handling:
// TUnit.Assertions/Conditions/EquatableAssertion.cs:77-80
if (!value.HasValue)
{
return Task.FromResult(AssertionResult.Failed("value was null"));
}Test Coverage ⭐⭐⭐⭐⭐Comprehensive Test Suite:
Test Quality Examples:// Tests realistic scenarios from issue #2972
[Test]
public async Task GitHubIssue2972_Example()
{
Wrapper value = new() { Value = 1 };
await Assert.That(value).IsEqualTo(1L); // This is what users wanted!
}TUnit Guidelines Compliance ⭐⭐⭐⭐⭐Follows All Critical Rules:
Minor Suggestions for Enhancement1. Consider Adding Analyzer Support// Future enhancement: Add analyzer to suggest this overload when appropriate
// Could detect: struct Foo : IEquatable<int> and suggest using the new overload2. Documentation EnhancementConsider adding a usage example in XML docs showing the exact GitHub issue scenario: /// <example>

/// public bool Equals(long other) => Value == other;

///
/// await Assert.That(wrapper).IsEqualTo(42L); // Now possible!

where TActual : IEquatable<TExpected>This design allows Potential Issues Found ⭐⭐⭐⭐⭐None! This is exceptionally clean code with no bugs, security issues, or performance problems identified. Final Verdict: ✅ READY FOR MERGEThis PR demonstrates excellent software craftsmanship:
Recommendation: Approve and merge immediately. This is exactly the kind of thoughtful, well-implemented enhancement that makes TUnit better for its millions of users. |
…rtion library - Introduced EquatableAssertion<TActual, TExpected> for asserting equality between two types. - Added NullableEquatableAssertion<TActual, TExpected> to handle nullable types in assertions. - Updated various extension methods to remove redundant overloads and improve clarity. - Ensured consistency across .NET 4.7, .NET 8.0, and .NET 9.0 verified files.

- Implemented support for chaining assertions using And/Or logic in Assertion class. - Added methods to map exceptions in AssertionContext and EvaluationContext. - Introduced new assertion classes for checking exception messages: - ExceptionMessageContainsAssertion - ExceptionMessageEqualsAssertion - ExceptionMessageNotContainsAssertion - ExceptionMessageMatchesPatternAssertion - ExceptionMessageMatchesAssertion - ExceptionParameterNameAssertion - Updated existing assertion extensions to utilize new exception mapping methods. - Created CombinerType enum to specify assertion combination logic.
