gRPC client do not return immediately after receiving a status

[pablochacin]

Brief summary

When testing the injection of faults in grpc protocol using the xk6-disruptor extension I notice the requests made with the k6 grpc client did not return immediately after receiving an error status but waited until the timeout specified in the invoke options.

This behavior differs from the behavior observed with for example grpc-client-cli which returns immediately on receiving an error.

k6 version

0.42

OS

Linux

Docker version and image (if applicable)

No response

Steps to reproduce the problem

Follow the instructions) for injecting errors using the xk6-disruptor extension.

Note: Using the grpcnbin RandomError method will not show this as it returns an empty message after setting the status code.

Expected behaviour

The invoke function returns immediately regardless of the timeout specified when invoking the grpc method.

Actual behaviour

The invoke method waits until the timeout is expired and then returns the fault.
