f-trycua's #50855 test file predated the cross-platform PR (#50552) and reintroduced two stale tests asserting Linux is unsupported (test_*_non_macos_*, patching platform.system="Linux" and expecting a no-op/warn). Linux + Windows are supported now, so install proceeds on those platforms. Restore main's cross-platform-correct versions: test_*_on_unsupported_platform_* using FreeBSD as the genuinely unsupported case.

"""Tests for ``install_cua_driver`` upgrade semantics.
|
|
|
|
The cua-driver upstream installer always pulls the latest release tag, so
|
|
re-running it is the canonical upgrade path. ``install_cua_driver(upgrade=True)``
|
|
must:
|
|
|
|
* Be macOS-only — no-op silently on Linux/Windows so ``hermes update`` can
|
|
call it unconditionally without warning every non-macOS user.
|
|
* Re-run the installer even when the binary is already on PATH (this is the
|
|
fix for the "we only pulled cua-driver once on enable" complaint).
|
|
* Preserve original ``upgrade=False`` behaviour for the toolset-enable flow:
|
|
skip if installed, install otherwise, warn on non-macOS.
|
|
|
|
The pre-install arch probe that used to live alongside this function was
|
|
deleted (see top-of-file comment in tools_config.py) — the upstream
|
|
installer has CUA_DRIVER_RS_BAKED_VERSION baked in by CD and errors
|
|
cleanly on missing-arch assets, and the upgrade path uses
|
|
``cua_driver_update_check()`` (which shells `cua-driver check-update
|
|
--json` against the already-installed binary).

"""Regression tests for the deletion of `_check_cua_driver_asset_for_arch`.
|
|
|
|
The old probe queried ``/releases/latest`` on trycua/cua and inspected
|
|
asset names. That was wrong in two ways:
|
|
|
|
1. cua-driver-rs releases are marked **prerelease** on every cut, so
|
|
``/releases/latest`` returns the Python ``cua-agent`` / ``cua-computer``
|
|
package instead — a release with zero binary assets. The probe then
|
|
reported "no asset for $arch" on Linux x86_64, Windows, macOS Intel,
|
|
Linux arm64 — every non-Apple-Silicon host.
|
|
2. Even with the right endpoint, it duplicated tag-resolution the upstream
|
|
installer already does correctly via ``CUA_DRIVER_RS_BAKED_VERSION``
|
|
(auto-baked by CD on every release).
|
|
|
|
The fix: stop probing. Trust the upstream installer for fresh installs
|
|
(it has the baked version + correct API fallback) and the
|
|
``cua-driver check-update --json`` MCP-binary native command for the
|
|
upgrade path.
