• Review PR #aw_pr_ueaof: test: add edge case tests for UseExecuteAsyncOverrideFixer — 3 new tests covering untested guard branches (no public modifier, zero params, wrong param type); 9/9 pass - View

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.

• 🔧 Created PR #aw_pr_ueaof: test: add edge case tests for UseExecuteAsyncOverrideFixer — 3 new tests covering IsExecuteMethodOverride guard branches: no public modifier (protected override → no fix), zero parameters (→ no fix), wrong parameter type (int instead of ITestMethod → no fix); 9/9 pass

2026-06-24 23:20 UTC - Run

• 🔧 Created PR #aw_pr_rcba: test: add edge case tests for RemoveClassCleanupBehaviorArgumentFixer — 2 new tests: ClassCleanupBehavior as first argument (removes it, keeps InheritanceBehavior.None); non-attribute context reference (no fix registered, guard exercised); all 4 tests pass
• ✅ PR [test-improver] test: add edge case tests for PreferTestCleanupOverDispose and PreferTestInitializeOverConstructor analyzers #9382 merged (PreferTestCleanupOverDispose + PreferTestInitializeOverConstructor edge cases — full dispose pattern, Dispose+TestCleanup coexistence, static constructor; merged 2026-06-24)

• 🔧 Created PR (now [test-improver] test: add edge case tests for PreferTestCleanupOverDispose and PreferTestInitializeOverConstructor analyzers #9382, merged 2026-06-24): test: add edge case tests for PreferTestCleanupOverDispose and PreferTestInitializeOverConstructor analyzers — 3 new tests: full dispose pattern (only Dispose() flagged not Dispose(bool)), Dispose+TestCleanup coexistence (Dispose still flagged), static constructor (not an instance ctor); all 14 tests pass
• ✅ PR [test-improver] test: add edge case tests for UseCancellationTokenPropertyAnalyzer (MSTEST0054) #9355 merged (UseCancellationTokenPropertyAnalyzer MSTEST0054 edge cases — TestInitialize, non-TestContext symbol precision, AssemblyInitialize parameter receiver; merged 2026-06-23)

2026-06-21 23:22 UTC - Run

• 🔧 Created PR [test-improver] test: add edge case tests for async-suffix suppressors and redundant display name analyzer #9314 (merged 2026-06-22): test: add edge case tests for async-suffix suppressors and redundant display name analyzer — 4 new tests: custom-derived attribute diagnostic in MSTEST0071, custom-derived attribute suppression in MSTEST0027, non-TestMethod not-suppressed in MSTEST0027, no-fixture-attribute not-suppressed in MSTEST0028; 16 tests pass
