Allow deserializing models with json files in tests

[scottkennedy]

I'm trying to write some unit tests where I need the model objects, but there doesn't seem to be a way of doing this without setting up a mock server that takes in a request, which is a lot of overhead for a unit test.

I'm not sure I understand what you are trying to achieve or what is lacking?

You can try to replicate the logic inside server response body parser https://github.com/apollographql/apollo-android/blob/master/apollo-runtime/src/main/java/com/apollographql/apollo/internal/interceptor/HttpResponseBodyParser.java#L36

where you replace response.body().source() with json string

@sav007 What about the case where I don't want to mock an entire query? For example, what if I want to just want to deserialize some fragment with some JSON and use that in my test? Is there any way to do that?

Can you use mockito?

Mocking a JSON model is a lot of effort, I would rather use JSON and deserialize my models from that

[sav007]

@mandrizzle any model generated by Apollo including fragments, has a Mapper class, that can be used to deserialize from JSON. It has one method map(ResponseReader) where response reader can be custom implementation that backed by string json.

Do you have any example of a customer reader?

I don't have right now, but will come up with smth later this week

Guys thanks a lot for this. You've saved a me a lot of effort in my unit tests.
