# Mock SessionLocal to return the test session
|
|
# We need a factory that returns the session, but SessionLocal() creates a new session.
|
|
# So we mock SessionLocal to return a mock that acts like a session but is actually our test session.
|
|
# However, our test session is scoped to the function.
|
|
# A better approach is to use a separate engine for the background task or share the connection.
|
|
# Since we use SQLite in-memory, sharing connection is key.
|
|
# But process_item_check creates a NEW session.
|
|
|
|
# Let's mock SessionLocal to return a session bound to the SAME engine.
|
|
# But we are using StaticPool, so all sessions share the same connection.
|
|
# So we just need SessionLocal to return a session from TestingSessionLocal.
