Suggested Actions for Maintainer

• Review PR [test-improver] test: add edge case tests for UseDeploymentItemWithTestMethodOrTestClass (MSTEST0035) — 3 new tests: static class behavior, DataTestMethod inheritance, multiple attrs - 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. DoNotUseSystemDescriptionAttributeAnalyzer — Missing test for inherited [TestMethod] (e.g. [DataTestMethod] + [System.ComponentModel.Description]) to verify the Inherits() check.
