Square retrofit server mock for testing

Question

What\'s the best way to mock a server for testing when using the square retrofit framework.

Potential ways:

1. Create a new retrofit client and set it

Answer 1

Mocking api calls with Retrofit is now even easier with Mockinizer which makes working with MockWebServer really straight forward:

import com.appham.mockinizer.RequestFilter
import okhttp3.mockwebserver.MockResponse

val mocks: Map = mapOf(

    RequestFilter("/mocked") to MockResponse().apply {
        setResponseCode(200)
        setBody("""{"title": "Banana Mock"}""")
    },

    RequestFilter("/mockedError") to MockResponse().apply {
        setResponseCode(400)
    }

)

Just create a map of RequestFilter and MockResponses and then plug it into your OkHttpClient builder chain:

OkHttpClient.Builder()
            .addInterceptor(loggingInterceptor)
            .mockinize(mocks) // <-- just plug in your custom mocks here
            .build()

You don't have to worry about configuring MockWebServer etc. Just add your mocks all the rest is done by Mockinizer for you.
