Passing metadata

[Arrekin]

Is there a way to pass metadata?

Normally I can invoke it like this:
grpc_stub.SomeGrpcMethod(SomeRequest(), metadata=some_metadata)

But I get:
TypeError: fake_handler() got an unexpected keyword argument 'metadata'

I can see fake_handler takes only request as argument.

Same problem here, any updates?

Hackish, but does the job:

from pytest_grpc.plugin import FakeContext

some_metadata = dict(a='b', c='d...')
if 'FakeChannel' in repr(grpc_stub.SomeGrpcMethod):
    # pytest grpc operating in 'fake server mode' (--grpc-fake-server flag provided)
    # Circumvent bug: https://github.com/kataev/pytest-grpc/issues/6
    # Patch the getter function to return our metadata.
    monkeypatch.setattr(FakeContext, 'invocation_metadata', lambda _self: some_metadata.items())
    return grpc_stub.SomeGrpcMethod(SomeRequest())
else:
    # default
    return grpc_stub.SomeGrpcMethod(SomeRequest(), metadata=some_metadata.items())

Put this in your test function or a function-scoped fixture, and add monkeypatch to the argument list
