# grpc-mock
Easy gRPC server mocking for [grpc Elixir library](https://github.com/tony612/grpc-elixir)
A lot of concepts and code taken from [mox library](https://github.com/plataformatec/mox).
## Installation
Just add `GrpcMock` to the list of dependencies in mix.exs:
```
def deps do
  [
    {:grpc_mock, "~> 0.1", only: :test}
  ]
end
```
## Example
Create mocked gRPC server:
```
GrpcMock.defmock(MockedServer, for: Helloworld.Greeter.Service)
```
Start gRPC server:
```
GRPC.Server.start(MockedServer, 50051)
```
Connect to the server:
```
{:ok, channel} = GRPC.Stub.connect("localhost:50051")
```
Setup stub on mocked server:
```
GrpcMock.stub(MockedServer, :say_hello, fn(request, stream) ->
  Helloworld.HelloReply.new(message: request.name)
end)
```
Call the server:
```
name = "bob"
request = Helloworld.HelloRequest.new(name: name)
assert {:ok, reply} = Helloworld.Greeter.Stub.say_hello(channel, request)
assert reply.message == name
```
