tests/test_alembic.py points Alembic at an in-process SQLite database in --sql mode so the migration files are validated end to end without needing the real Postgres compose service. Asserts the documents, chunks, and processing_events tables plus the unique constraints appear in the generated DDL, and that the revision graph stays linear at 0001_initial. tests/test_routes_search.py monkeypatches app.indexing.hybrid_search.run_search so the FastAPI route can be exercised with the real SearchRequest/SearchResponse schemas. Covers the happy path (rank, citation, reranked flag) and that empty queries are rejected at schema validation before the backend is called. pytest tests/test_alembic.py tests/test_routes_search.py -q: 4 passed.

"""Alembic migration smoke test.
|
|
|
|
We do not boot a real Postgres in CI; instead we point Alembic at an in-process
|
|
SQLite database and verify:
|
|
|
|
- ``alembic upgrade head`` succeeds offline (SQL generation) using the real
|
|
migration files, exercising every column type and constraint declaration;
|
|
- ``downgrade base`` rewinds without errors.
|
|
|
|
This catches typos and broken migration ordering early without requiring the
|
|
full backing-service compose stack to be online.
