Suggested Actions for Maintainer

• Review PR [test-improver] test: add edge case tests for PublicTypeShouldBeTestClassAnalyzer (MSTEST0004) — 5 new tests for record types and nested class visibility - 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.

Discovered Commands
