From 34053b3fc13b5c5bbe444e8a8d256a73f9a148eb Mon Sep 17 00:00:00 2001 From: aserrador Date: Wed, 10 Jun 2026 16:06:10 -0500 Subject: [PATCH] fix: use in-memory checkpointer for API tests to avoid database dependency - Replace PostgreSQL AsyncPostgresSaver with MemorySaver in test fixtures - Create test_app fixture with test_lifespan using in-memory dependencies - Mock LLM model to avoid requiring API keys during tests - Update test_api.py to use test_app fixture instead of production app - Fix test_root endpoint URL to match root_path configuration - All API tests now pass without requiring external services (0.06s vs 30s+ timeout) This change allows tests to run in isolation without PostgreSQL or API keys, making them faster and more reliable for CI/CD and local development. --- src/naliiabotapi/main.py | 11 +++--- tests/conftest.py | 76 +++++++++++++++++++++++++++++++++++++--- tests/test_api.py | 12 ++++--- 3 files changed, 86 insertions(+), 13 deletions(-) diff --git a/src/naliiabotapi/main.py b/src/naliiabotapi/main.py index 5da6d10..24d009f 100644 --- a/src/naliiabotapi/main.py +++ b/src/naliiabotapi/main.py @@ -5,7 +5,9 @@ from naliiabot.bot.factories.llm_factory import LLMFactory from naliiabot.bot.prompts.load_prompt import get_prompt_template from naliiabot.bot.tools.naliia_tools import NaliiaTools from naliiabotapi.api.v1.endpoints.chat import router as chat_router -from naliiabotapi.api.v1.webhooks.chat_hook import router as chat_hook_router +from naliiabotapi.api.v1.webhooks.chat_hook import ( + router as chat_hook_router, +) import naliiabotapi.api.dependencies as deps from contextlib import asynccontextmanager from langgraph.checkpoint.postgres.aio import AsyncPostgresSaver @@ -30,7 +32,7 @@ async def lifespan(app: FastAPI): model=model, config=config, checkpointer=checkpointer, -
