- windows-test-env.js gains resolvePython: it probes each candidate with
`-c "import sys; sys.exit(0 if sys.version_info[0] == 3 else 1)"`, so the
Store stub is rejected.
- hermes-hooks.test.js launches its four hook spawns through the resolved
interpreter, falling back to python3 when none is found so a machine
without Python still fails loudly instead of skipping.
hermes-hooks goes from 0/14 to 14/14 on Windows 11; the other users of the
helper are unchanged. Product code is untouched: Hermes runs these hooks
itself and the installer writes no interpreter.
On a Windows machine with Claude Code installed natively, Git for Windows,
and the ECC plugin installed, `node tests/run-all.js` on main fails 44 tests
in 7 files. Linux CI never sees them. Three of the four causes are test
isolation gaps, fixed here (43 tests):
- claude-plugin-setup, claude-scope-migration, setup (38): fixtures put a
fake claude.cmd first on PATH, but on Windows spawning a bare `claude`
resolves only .com/.exe, so a native ~/.local/bin/claude.exe ran instead
of the fake. Fixture PATHs now drop entries holding claude.exe/claude.com.
- ecc-universal-bin, eval-harness-package (4): tar received an absolute
C:\ archive path, which Git Bash's GNU tar reads as a host:path remote
spec ("Cannot connect to C: resolve failed"). Extract from inside the
destination with a relative, forward-slash archive name, which both GNU
tar and bsdtar accept.
- harness-audit (1): the cache-layout test overrode HOME only, while
findPluginInstall also reads USERPROFILE and os.homedir(), so the real
installed plugin won over the fixture. Override USERPROFILE too.
The two helpers live in tests/lib/helpers/windows-test-env.js with a
platform-independent test, so Linux CI holds both invariants too.
The 44th failure, plugin-hook-bootstrap's no-bash test, is a production
bug rather than a test leak: System32\bash.exe launches an installed WSL
distro, which passes the bash probe. It gets a separate fix.
