Activity for July 2026

Suggested Actions for Maintainer

• Review PR for MSTEST0061 edge cases (OSPlatform.Create + mobile OS platforms): test-assist/mstest0061-edge-cases

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. Remaining candidates: any analyzers with unexercised guard paths.

Discovered Commands

• Build (Debug): ./build.sh (Linux)
• Restore SDK: ./build.sh --restore
• 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 "ClassName~Tests"
• Pack NuGets: ./build.sh -pack
• Integration Tests: ./build.sh -pack -test -integrationTest
