Activity for June 2026

Suggested Actions for Maintainer

• Review PR #aw_pr_uam: test: add edge case tests for UseAttributeOnTestMethodAnalyzer (MSTEST0007) — 2 new tests: [DataTestMethod] early-return path, [OSCondition] ConditionBase subclass fires ConditionBaseRule with concrete class name; 39/39 pass - Review

Maintainer Priorities

No specific priorities communicated yet.

Testing Opportunities Backlog

1. MSTest.Engine internal class coverage — TestArgumentsManager, TestFixtureManager, ThreadPoolTestNodeRunner are internal (~135+ LOC each). Would need InternalsVisibleTo or integration tests.
2. More Assert method coverage — Any remaining gaps in newer Assert overloads.
3. Analyzer edge cases (ongoing) — Continue systematic coverage of untested paths in MSTest.Analyzers.
   • UseCooperativeCancellationForTimeoutAnalyzerTests (14 tests) — well covered
   • PreferDisposeOverTestCleanupAnalyzerTests (11 tests) — covered relative to analyzer complexity
   • PreferConstructorOverTestInitializeAnalyzerTests (15 tests) — covered relative to analyzer complexity

Discovered Commands

• Build (Debug): ./build.sh (Linux)
• Unit Tests: ./build.sh -test
• Single analyzer test run: .dotnet/dotnet test test/UnitTests/MSTest.Analyzers.UnitTests/MSTest.Analyzers.UnitTests.csproj -f net8.0 --no-build -c Debug --filter "FullyQualifiedName~Tests"
• Pack NuGets: ./build.sh -pack
• Integration Tests: ./build.sh -pack -test -integrationTest
