MY LIMITER METHODS ------------------------------------
async def ip_identifier(request: Request):
    forwarded = request.headers.get("X-Forwarded-For")
    if forwarded:
        return forwarded.split(",")[0]
    return f"{request.client.host}:shared-limit"

def get_shared_limiter():
    return shared_limiter

def get_rate_limiter() -> RateLimiter:
    return RateLimiter(
        limiter=get_shared_limiter(),
        identifier=ip_identifier
    )

MY APP LIMITER SETUP ----------------------------------
app = FastAPI(
    dependencies=[
        Depends(
            get_rate_limiter()
        )
    ],
)

MY CURRENT TEST SETUP (DOES NOT WORK) -----------------
@pytest.fixture(autouse=True, scope="session")
def mock_limiter():
    app.dependency_overrides[get_rate_limiter] = lambda: RateLimiter(limiter=Limiter(Rate(100000, Duration.SECOND)), identifier=ip_identifier)
