blackbull.testing.grpc

Loopback gRPC test server.

Status lives in trailers, so an in-process ASGI transport that loses trailers cannot establish gRPC completion. This helper does not provide a general gRPC client.

GrpcReply dataclass

One gRPC call's reply, judged as a gRPC client must (PROTOCOL-HTTP2.md).

GrpcTestServer

Serve app on an ephemeral h2c port and call its gRPC methods.

async with only: the server shares the test's event loop, as it shares the process loop in production.

unary(method, request=b'', *, metadata=None, timeout=5.0) async

Call method with one request message and read the reply.

The length-prefixed framing is applied for you: pass the message bytes your servicer expects to receive, not an encoded frame.
