🧐 About

servermock is a go package that can be used to mock out http or grpc servers simply without any external server implementations.

🚀 Usage

Inline in golang

1. Start a server

err := servermock.Serve(ctx, Printf, ":8000")

1. Set the response

err = servermock.SetResponse("http://localhost:8000", servermock.Request{
		Path:       "/foo.service.bar.SomethingAPI/GetWhatever",
		Body:       []byte(`{"Hello": "true"}`),
		StatusCode: 200,
	})

1. Send a request

resp, err := http.Get("http://localhost:8000/foo.service.bar.SomethingAPI/GetWhatever")
// {"Hello": "true"}

In a docker container

1. Run the docker container

docker run -p 8000:8000 joshcarp/servermock

1. Set the response conforming to the servermock.Request type

curl --header "Content-Type: application/json" --header "SERVERMOCK-MODE: SET" --request POST --data '{"path":"/foo.service.bar.SomethingAPI/GetWhatever","body":"eyJIZWxsbyI6ICJ0cnVlIn0=","status_code":200' http://localhost:8000/foo.service.bar.SomethingAPI/GetWhatever

1. Send a request

curl localhost:8000/foo.service.bar.SomethingAPI/GetWhatever
> {"Hello": "true"}                                                                                                  

gRPC vs REST servers

Setting data always occurs over http 1.0 using the json payload, gRPC servers are, after all, just servers that return some bytes.

• @emmaCullen had the original idea for this package.
• github.com/dnaeon/go-vcr is similar but different; whilst any network traffic can be recorded and replayed, servermock tries tosimplify mocking of servers in unit tests/contexts where writing a specific server implementation is a little too much.
