AFFECTSRootCause

every browser has a specific limit for parallel connections to a given hostname — In Chrome and FireFox, for instance, that is 6. Tension: all subsequent requests would get stalled and queued.

AFFECTSRootCause

you probably will need to use and async client with the asyncio pytest plugins — Since you're writing an async lifespan. Tension: sync/async issue.

AFFECTSRootCause

Wrapping the entire `httpx.AsnyncClient()` in the async function `stream_response()`. Outcome: and yielding from there.

AFFECTSRootCause

FastAPI and Starlette versions were incompatible (FastAPI 0.101.1 with Starlette 0.46.0), causing request parsing/handling to fail at runtime.

AFFECTSRootCause

if the function declares the input parameter with `Annotated` and `Depends` — a simple API created in python with FastApi. Tension: the test fails. Outcome: The route responds with a 422 Unprocessable Entity status code.

REQUIRESSolution

use httpx or aiohttp e.g: — async def test_api(request: Request):. Tension: requests(which is synchronous) inside async function. Outcome: async with client.stream("POST", "http://127.0.0.1:8000/test_api",json={} ) as response: async for chunk in response.aiter_bytes(chunk_size=1234): yield chunk.

REQUIRESSolution

Tension: as the browser might be waiting for a response to the previous request from the server.

REQUIRESSolution

use `pytest_asyncio` and the async fixture — If you don't want to utilize an `AsyncClient` like the one by `httpx`. Tension: ensuring that the FastAPI app's lifespan context correctly works.
