各位大神好，小弟目前正在試著使用 FastAPI 的 TestClient 進行測試程式的撰寫，以下是我的程式碼

base_test_case

class APIBaseTestCase(unittest.TestCase):
    @staticmethod
    def _session_override():
        with Session(test_db_engine) as session:
            yield session

    def setUp(self):
        app = FastAPI()
        app.include_router(router=router)
        SQLModel.metadata.create_all(test_db_engine)
        app.dependency_overrides[get_session] = self._session_override
        self.test_client: TestClient = TestClient(app=app)

        ...

    def tearDown(self):
        SQLModel.metadata.drop_all(test_db_engine)

test_case.py

class TestDemo(APIBaseTestCase):
    def test_demo(self):
        response = self.test_client.get("<url>")
        print(response.status_code)
        print(response.json())

        assert response.status_code == 200
        ...
        ...

.gitlab-ci.yml

stages:
    - backend-api-test

backend-api-test:
    stage: backend-api-test
    script:
        - pip3 install -r ./backend/requirements.txt
        - pytest -v ./backend/test/api/endpoints/test_case.py
    tags:
        - demo-runner

目前我碰到的問題是，上面的寫法在本地端使用 IDE or CMD 執行的時候都沒有問題，但是將程式 push 上 gitlab 後，利用 cicd container (python 環境) 進行測試時，test_case.py 內的測試項目會回傳 404 status code，想問問各位大神有沒有類似的經驗，或是我的寫法有哪些地方可以改正的?

補上其中一個 test case 的錯誤 log

    def test_get_total_client_count(self):
        with Session(db_engine) as session:
            create_client(session=session)
            response = self.test_client.get("/api/client/count", headers=self.headers)
            print(response.status_code)
            print(response.text)
