Standalone Test Repro Cmd

Resolve a Runtime Test Wrapper

This is the wrapper-path resolution sub-skill for ../standalone-test-repro/SKILL.md. Resolve the exact source test, owning project, and effective invocation, then continue with the parent's shared extraction steps.

Input

Accept a generated .cmd or .sh path copied from a CI failure, for example:

JIT\Directed\ConvertToInt\checked\ConvertToInt.cmd

The path may be absolute, relative to a Helix work item or runtime test output root, and may use either directory separator. The surrounding request may also name a scenario such as jitstress1; preserve it separately from the path for the parent workflow.

Resolution

1. Normalize the identifier:
   • Trim quotes, Markdown formatting, leading test-result labels, and trailing punctuation.
   • Remove command-line arguments while retaining the path through .cmd or .sh.
   • Convert separators only for host filesystem operations.
   • Do not treat a separately supplied scenario as part of the wrapper path.
2. If the wrapper exists locally, read it and record:
   • The managed assembly or executable
   • corerun arguments, including -p and -e
   • Test arguments and expected exit code
   • Environment variables
   • Target-specific batch or Bash pre/post commands
   • Working-directory assumptions
   • Copied data or native dependencies
3. Map an artifact or Helix path back to src/tests/:
   • Strip prefixes through the runtime test output root.
   • Remove configuration-only artifact path segments.
   • Search the remaining relative directory for the wrapper stem, likely .csproj, source file, and matching AssemblyName.
4. If the wrapper is unavailable, use the path and stem to search under src/tests/; derive invocation settings from the project.
5. Inspect the owning project, applicable imports, and its explicit or evaluated Compile items. Evaluate target-specific environment items and CLRTestBatchPreCommands, CLRTestBashPreCommands, CLRTestBatchPostCommands, and CLRTestBashPostCommands.
6. Confirm the assembly contains only the requested runnable test. If it contains multiple independently runnable tests, stop and ask for a fully qualified method name.

Do not assume a wrapper only runs corerun Test.dll. Its host options, environment, arguments, setup, and working directory may be required to reproduce the failure. When available, the generated wrapper is the ground truth for the effective invocation.

Resolution is complete only when the exact source method, owning project, and effective invocation are known. Return any requested scenario unchanged for canonicalization by the test-scenario-env skill.
