테스트 코드 오류

안녕하세요 테스트 코드 사용 중 오류가 잡히지 않아서 문의 드립니다.

강의에서 설명해주신 것처럼 아래와 같이 코드를 작성했지만 오류가 발생합니다.

어떻게 해야 할까요?

from fastapi.testclient import TestClient
from main import app

# api들이 있는 app을 검증할 클라이언트 생성
client = TestClient(app=app)

def test_health_check():
    # api 요청
    response = client.get("/")

    # 반환 값 검증
    assert response.status_code == 200
    assert response.json() == {"ping": "pong"}

아래는 오류 내용 입니다.
