老獅：我們來加強我們的登入測試，拿完 token 以後把他拿去打 /v1/auth/users/tokens/info 期望他可以回應我們正確的資訊

# src/tests/test_services/test_token.py
import httpx
import pytest

from app import main


@pytest.mark.asyncio
async def test_create_jwt_token_by_username_and_passowrd():
    async with httpx.AsyncClient(app=main.app, base_url="http://test") as client:
        resp = await client.post(
            "/v1/auth/users/tokens", json={"username": "test", "password": "testme"}
        )
        assert resp.status_code == 200
        data = resp.json()
        assert (access_token := data["access_token"])
        assert data["refresh_token"]
        resp = await client.get(
            "/v1/auth/users/tokens/info",
            headers={"Authorization": f"Bearer {access_token}"},
        )
        assert resp.status_code == 200
        assert resp.json()["username"] == "test"

export PYTHONPATH=$PWD/src
pytest src

...
>           assert resp.status_code == 200
E           assert 404 == 200
E            +  where 404 = <Response [404 Not Found]>.status_code

src/tests/test_services/test_token.py:21: AssertionError
=========================== short test summary info ============================
FAILED src/tests/test_services/test_token.py::test_create_jwt_token_by_username_and_passowrd - assert 404 == 200
========================= 1 failed, 1 passed in 0.39s ==========================

小獅：我會，加入新的函數去處理這個路徑，這簡單

# src/app/api/v1/endpoints/auth/users/tokens.py

@router.get("/info")
def get_jwt_token_info():
    return {"username": "test"}

老獅：沒錯，我們再跑一次測試

export PYTHONPATH=$PWD/src
pytest src

老獅：很棒，先提交吧

git add src/app/api/v1/endpoints/auth/users/tokens.py
git add src/tests/test_services/test_token.py

git commit -m "feat: get username from token info"

小獅：但是這樣測試很不完整吧？我們根本沒有驗證

老獅：是的，接下來我們就要把整個測試改進成為比較完整一點，例如我們可以測試不同帳號密碼登入以後拿到的帳密不一樣

小獅：只有兩個還是可以用騙的吧？

老獅：確實，所以這都是建立在你已經知道如何建立系統的情況下，我們知道為了符合更多種類的變異性，我們必須要把使用者資訊存起來，例如帳號密碼，最後我們就可以用存下來的帳號密碼來做驗證，分別給不同使用者發出不同的 token

小獅：終於要導入資料庫了，我們如何開始？
