"""Live network verification of the probe-first asset resolution path.
|
||
|
|
|
||
|
|
The unit tests in ``tests/unit/test_asset_resolver.py`` cover every
|
||
|
|
branch with mocks. This integration test exercises the real
|
||
|
|
``https://file.infinito.nexus/assets/img/logo.png`` endpoint that
|
||
|
|
``app/config.sample.yaml`` references for the Infinito.Nexus card. A
|
||
|
|
green run proves the production resolver behaviour end-to-end:
|
||
|
|
|
||
|
|
* probe (HEAD ``image/*``) succeeds against the canonical Infinito.Nexus
|
||
|
|
asset host, so ``external_url`` is populated directly and **no**
|
||
|
|
download is performed (the cache directory stays empty).
|
||
|
|
|
||
|
|
The download-fallback branch (probe fails → ``cache_manager.cache_file``
|
||
|
|
serves the asset locally) is intentionally not exercised against a live
|
||
|
|
endpoint here — it is covered by mocked unit tests because every
|
||
|
|
candidate "HEAD-fails, GET-succeeds" public URL we tried was flaky
|
||
|
|
(Nextcloud's ``/download`` endpoint sporadically times out on HEAD even
|
||
|
|
when GET works), which would make this guard test non-deterministic.
