Moq.Analyzers 0.4.2 🎉

This is a focused patch release with one mission: squash a false positive that was getting in the way of real-world LINQ-to-Mocks usage. If you've been seeing Moq1302 warnings on perfectly valid code, this one's for you. 🎯

A big thank you to @abatishchev for reporting the issue with a clear, actionable reproduction. Community reports like this make all the difference.

🐛 False Positive Fix for Moq1302

What was happening

If you were using Mock.Of with a comparison expression — something totally normal like this:

Mock.Of<Response>(static r => r.Status == StatusCodes.Status200OK)

…you'd get a warning:

⚠️ Moq1302: Invalid member 'StatusCodes.Status200OK' in LINQ to Mocks expression

But there's nothing wrong with that code. It compiles, it runs, and it's how LINQ-to-Mocks expressions are supposed to work. The right-hand side of the comparison (StatusCodes.Status200OK) is just a constant — it's not a mock setup member. The analyzer shouldn't have been looking at it at all. 😬

The same false positive appeared with enum values, static fields, external locals, and other non-mock expressions on the right-hand side of ==, &&, or || comparisons.

How it was fixed

The fix introduces a lambda parameter guard: before the analyzer flags a member access, it now walks the receiver chain to check whether the operation is actually rooted in the lambda parameter (i.e., the r in r => r.Status == ...).

A new IsRootedInLambdaParameter() extension method traces the receiver chain — through property accesses, method calls, and conversions — all the way back to the lambda parameter. If the chain doesn't terminate in the lambda parameter, the member is silently skipped. Static members, constants, and external references pass right through without a warning.

The guard is applied only to leaf member operations (property references, method calls). Composite operations like && and || still get decomposed normally, so chained comparisons like r.Prop == "a" && r.Other == "b" continue to be fully analyzed. No false negatives.

As a bonus, MoqKnownSymbols is now threaded through the entire analysis chain instead of being recreated mid-analysis, and nested Mock.Of calls are excluded early to prevent false positives from inner mock expressions.

🧪 Comprehensive Test Coverage

This release adds 961 new lines of test code covering the full surface area of the fix (#1020):

  • ✅ Static members and constants on the right-hand side of comparisons
  • ✅ Enum value comparisons
  • ✅ Chained && / || expressions
  • ✅ Nested Mock.Of calls
  • ✅ Deep receiver chain walking edge cases

👥 Contributors

Thank you to everyone who reported bugs and provided reproduction cases:

Moq.Analyzers 0.4.1

This is a patch release addressing critical bugs reported after v0.4.0.

🐛 Bug Fixes

Moq1203 False Positives

  • #849 - Fixed incorrect Moq1203 flagging after upgrading to v0.4.0. The analyzer now correctly resolves delegate-overload resolution for ReturnsAsync, Callback, and similar chained methods. (#886, #919)
  • #887 - Fixed Moq1203 false positive when the Setup call is wrapped in parentheses. (#895)

Parenthesized Expression Handling

  • #896 - Fixed parenthesized expressions breaking syntax chain walking in Moq1100 and Moq1206 analyzers. (#907)

Assembly Loading

  • #850 - Resolved CS8032 warning caused by System.Collections.Immutable assembly version mismatch. (#888)

v0.4.1-alpha

v0.4.1-alpha

Prerelease containing 3 bug fixes since v0.4.0 to rebuild confidence with users.

Bug Fixes

  • fix: Moq1203 false positives for ReturnsAsync and Callback chaining (#886)
  • fix: resolve CS8032 assembly version mismatch (#850) (#888)
  • fix: Moq1203 false positive when Setup call is wrapped in parentheses (#895)

Critical: CS8032 Fix

v0.4.0 shipped DLLs that referenced System.Collections.Immutable versions incompatible with .NET 8 SDK hosts, causing CS8032 warnings on every build. This release downgrades the transitive dependency pins and adds CI load tests to prevent recurrence.

Moq.Analyzers 0.4.0

Welcome to Moq.Analyzers 0.4.0! This major release brings significant improvements to code quality analysis, introduces new analyzers for better Moq usage patterns, and includes comprehensive updates to our infrastructure and dependencies.

✨ Highlights

New Analyzers

This release introduces three powerful new analyzers to help you write better Moq tests:

  • [Moq1207] - SetupSequence validation analyzer ensures sequential setups are used correctly
  • [Moq1420] - Times usage validation helps you use verification times specifications properly
  • [Moq1500] - Raise method validation catches incorrect event argument patterns

Enhanced Diagnostic Messages

We've improved diagnostic messages across all analyzers to include specific type and member names, making it easier to identify and fix issues. Every analyzer now provides clearer, more actionable feedback.

Symbol-Based Detection

Replaced string-based detection with comprehensive symbol-based analysis for the Raises method, improving accuracy and performance of event-related analyzers.

Infrastructure Modernization

  • Migrated to .NET 10 SDK for the latest tooling improvements
  • ARM64 runners for faster CI/CD on modern hardware
  • Enhanced performance testing with nightly regression detection
  • Automated dependency management with Renovate

🎯 Breaking Changes

Minimum SDK Version

Moq.Analyzers now requires minimum .NET SDK 8 for development. This aligns with the long-term support release and enables us to leverage modern C# features.

🔧 Analyzer Improvements

Coverage Expansion

We've significantly expanded test coverage for all Moq patterns:

  • Event patterns: Comprehensive coverage for SetupAdd, SetupRemove, Raises, and RaisesAsync
  • Async methods: Full support for Task/ValueTask patterns
  • LINQ to Mocks: Complete validation of query expressions
  • MockRepository: Validation for repository-based mock creation
  • Argument matching: Coverage for all It.* and custom matcher patterns
  • Protected members: Validation for .Protected().Setup() patterns
  • Callback signatures: Advanced callback pattern support including generic scenarios

Moq 4.16+ Compatibility

Added comprehensive test suites ensuring compatibility with Moq 4.16 and later versions, including new features like SetupProperty patterns.

Enhanced Validation

  • Moq1101: Now covers SetupProperty patterns in addition to existing validations
  • Moq1210: Improved verification pattern detection for non-overridable members
  • Moq1100: Validated support for advanced callback patterns

📊 Code Quality Enhancements

Improved Test Coverage

Achieved significant code coverage improvements through:

  • Data-driven test pattern adoption across all analyzers
  • Doppelganger tests to validate analyzer registration
  • Comprehensive edge case testing
  • Performance benchmark tests

Reduced Complexity
