Adds 44 focused tests under tests/plugins/web/ covering the surface that
the PR #25182 web-provider migration introduced. Complements the
existing tests/tools/ coverage which is dispatcher-centric; this file is
plugin-centric and tests each plugin + the registry directly.
Test classes (44 tests, ~1.1s on 4 workers)
-------------------------------------------
TestBundledPluginsRegister (16 tests)
- All seven plugins present in the registry after
_ensure_plugins_discovered()
- Per-plugin parametrized capability-flag assertions
(brave-free / ddgs / searxng: search-only;
exa / parallel / firecrawl: search + extract;
tavily: search + extract + crawl)
- Every plugin exposes name + display_name properties
- Every plugin returns a picker-compatible get_setup_schema() dict
TestIsAvailable (7 tests)
- Each premium plugin reports is_available()==False when its env var is
absent and True once set (brave-free / searxng / tavily / exa /
parallel)
- firecrawl recognizes either FIRECRAWL_API_KEY or FIRECRAWL_API_URL
as a "configured" signal
- ddgs is the always-on fallback and must not raise from is_available()
TestRegistryResolution (4 tests)
- Option B semantics validated end-to-end:
1. Explicit configured provider wins even when is_available()==False
(dispatcher surfaces typed credential errors, no silent switch)
2. Unknown/typo name falls back to first available legacy-preference
provider
3. Asking for extract via a search-only backend falls back to an
extract-capable available provider (capability-incompatible
branch in _resolve())
4. No config + no credentials → None (or ddgs if installed)
TestAsyncExtractDispatch (4 tests)
- parallel + firecrawl extract() are coroutine functions (async path
in dispatcher uses await)
- exa + tavily extract() are sync (dispatcher wraps in
asyncio.to_thread)
TestErrorResponseShapes (7 tests)
- Plugins return typed error dicts (success=False + "error" key) when
credentials are missing, never raise
- async extract() returns list of per-URL error dicts
- tavily crawl() returns {"results": [{"error": ...}]} on missing
credentials
Design notes
------------
- All tests use real imports of plugin modules — no mocking of provider
classes themselves — so they catch drift in the ABC, registry, and
glue layer simultaneously. Per the hermes-agent-dev skill's E2E
testing guidance.
- The autouse _isolate_env fixture clears every web-provider env var
before each test so is_available() reflects the test's setup.
- Resolution tests use the lower-level _resolve() directly rather than
rebuilding the HERMES_HOME config dance — same observable behavior,
no sys.modules.pop side-effects that would break the ABC isinstance
check inside ctx.register_web_search_provider().
