raise_for_status() raises httpx.HTTPStatusError for 4xx/5xx responses,
but the surrounding try/except only caught httpx.RequestError (network
errors) and RateLimitError (429). Any other HTTP error code propagated
uncaught up through chat_processor -> chat_helpers -> chat_routes and
surfaced as a 500 Internal Server Error.
Added an explicit except httpx.HTTPStatusError clause that logs a warning
and returns an empty result, matching the behaviour already in place for
network errors.
Also adds focused regression tests that exercise the real
fetch_webpage_content() path with a mocked _get_public_url:
- 403/404 responses return the standard empty-result shape instead of
raising, proving the new HTTPStatusError handling works end to end.
- 429 responses still take their own dedicated rate-limit branch (the
status_code == 429 check runs before raise_for_status() is reached),
keeping that behaviour distinct from the new generic HTTPStatusError
handling.
Dropped the unrelated builtin_mcp.py change that had been carried over
from a rebase; that fix is tracked separately in #2018 and this branch
should stay scoped to the search content fetch path.
Closes#2148
This file documents the shared test helpers and the review expectations that go
with them. The suite is being refactored incrementally, so this is a working
reference for that effort - not a claim that the suite is already fully
organized. Read it before adding a new helper or before reviewing a PR that
touches tests/helpers/.
For the broader rules - test taxonomy, determinism/isolation rules, the
behavioral-vs-source-text policy, and helper/factory extraction rules - see
TESTING_STANDARD.md. This file is the concrete helper
reference; that file is the standard the refactor works toward.
Core principles
Keep PRs small and homogeneous: one kind of change per PR.
Prefer explicit local setup over hidden global fixtures.
Avoid expanding the root conftest.py unless absolutely necessary.
Do not mix file moves with logic changes in the same PR.
Do not weaken tests with skip/xfail just to make CI pass.
Validate the focused files you changed, plus any neighboring or
order-sensitive groups they interact with.
Helper conventions
The helpers below live under tests/helpers/. They exist to remove repeated
boilerplate that already appeared across multiple tests. Reach for one only when
your test matches its intended use; do not stretch a helper to cover a new case.
tests.helpers.cli_loader.load_script
Use when a test needs to import a script under scripts/ without repeating
SourceFileLoader / importlib.util boilerplate.
Intended for script/CLI tests that load a single file from scripts/.
Not for arbitrary package imports - use a normal import for those.
When migrating an existing test to it, keep the existing stubs and assertions
unchanged. Any sys.modules stubs the script needs at import time must still
be injected (e.g. via monkeypatch) before calling load_script.
tests.helpers.import_state.clear_module
Use when a test must drop one cached module and its parent-package attribute
before a fresh import.
Clears sys.modules[name].
Clears the parent-package attribute when present.
Good replacement for local sys.modules.pop(...) + delattr(parent, child)
blocks.
tests.helpers.import_state.preserve_import_state
Use when a test temporarily installs stubs into sys.modules and needs
deterministic cleanup afterward.
Context manager: restores both sys.modules entries and parent-package
attributes on exit (normal or exception).
Useful around module-level stubs or temporary imports.
Prefer narrow, explicit module names over broad ones.
