SwiftyPrototype - use SwiftyMocky for fast prototyping

[amichnia]

Who uses Carthage probably noticed, that there is new framework being built (SwiftyPrototype). The reason for that is that we need two different and distinctive ways to use SwiftyMocky as a prototyping tool or unit testing tool.

We should investigate that area, and we need some requirements for the prototyping part. Some to start:

• [x] it needs to run on the device, and not import XCTest
• [x] we can rename ...Mock to ...Prototype

From the other requirements, just some ideas:

1. Make it easier to create 'partial' mocks. For prototyping it makes sense to mock parts that are not done yet, and use concrete implementation whenever possible. I see it something like Given(prototype, .method(willUse: concrete))

2. Refine variables, so they actually "store" a value.

3. Include new given type, allowing to contain custom logic. Something like:

Given(prototype, .method(param: .any, willReturn: { it, param -> Result in
  // alter prototype state
  // inspect params
  // custom logic
  return result
})

I believe it is connected to #79

I would appreciate any feedback to this topic.

I'm currently using SwiftyPrototype as it is. And it's doing it's job very well :-)

To your first idea: I think it should be possible to set a delegate on the prototype itself, which is used for method(...) if the delegate is set and neither Given(prototype, .method(willReturn: ...)) nor Given(prototype, .method(willProduce: ...)) has been called. I do not think that setting the delegate on a per-method-level is very important. On the contrary: If you only have a per-method-level configuration, it leads to more boilerplate in order to configure the prototype to use the delegate for all or many methods.

Well, we definitely need to have a way to replace some mocked methods with actual implementation during the development cycle, +1 for that.

I think I will give SwiftyPrototype more focus doing version 5, it is now just a mediocre twin brother of SwiftyMocky xD
