本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

- 符号
-
- fastapi.testclient.TestClient
- fastapi.HTTPException
- response_model
- lifespan
- pydantic.BaseModel
- httpx2.HTTPStatusError
- starlette.exceptions.StarletteDeprecationWarning
- 环境
- python 3.12

契约
- assert TestClient targets http://testserver, so the run needs no socket, no port and no DNS
- assert TestClient drives the real ASGI pipeline, so pure ASGI middleware runs and stamps a header on the response
- assert calling the endpoint function directly does no coercion, so it returns nonsense instead of a 422
- assert an int path parameter given text answers 422 with detail[0].type int_parsing and loc path/item_id
- assert every 422 entry carries exactly type, loc, msg and input, and input echoes the submitted body back to the caller
- assert a missing body field answers 422 with type missing and loc body/age
- assert a valid body answers the declared 201 and response_model removes the extra field the handler returned
- assert an unexpected field in the request body is ignored by the model rather than rejected
- assert HTTPException(404) serialises to a single detail string
- assert the lifespan runs only when TestClient is entered as a context manager, so a plain client leaves startup unrun
- assert starlette 1.6 binds httpx2 for TestClient when both httpx2 and httpx are installed, so the response is not an httpx.Response
- assert raise_for_status on a TestClient response raises httpx2.HTTPStatusError, which except httpx.HTTPStatusError does not catch
- assert fastapi.testclient.TestClient is starlette's class re-exported unchanged
- assert hiding httpx2 makes the import fall back to httpx with a StarletteDeprecationWarning, which is a UserWarning and not a DeprecationWarning
