This directory contains automated tests, manual diagnostic programs, and standalone experiments. It is separate from src so test-only dependencies and exploratory code are not included in production assemblies.

Directory map

Directory	Purpose
`StgSharpDebug`	Executable test harness for manual debugging and stress testing of allocators, matrices, rendering, NGRA, and other subsystems. This is not an automated unit-test suite.
`STgSharpTest`	Older MSTest-based tests for the former Script/EXPRESS and related projects. Some references and machine-specific test data are legacy and may require repair before the project can run.
`SingleFile`	Standalone source experiments and generated-code samples that are not part of a project or the normal build.

Run the active debug harness directly when investigating a subsystem:

dotnet run --project test/StgSharpDebug/StgSharpDebug.csproj

New repeatable tests should use a test project and avoid machine-specific paths, external mutable data, and dependencies on previous test execution. Keep one-off investigations in SingleFile or the manual debug harness until their expected behavior is stable enough for automation.
