UI tests without UI Testing experiment

This gist is a small experiment to see if there's an "in-between" for testing iOS applications. More feature-level than XCTest but not as heavy handed (or slow and brittle) as UI Testing.

The general idea is to provide an API similar to UI Testing but be able to spin up any controller on the fly. By putting the controller inside of a window the test behaves a bit more like the real app.

Currently, only two methods are explored: finding labels and buttons. An obvious omission is searching for the view recursively. A perhaps less obvious omission is still being able to tap disabled buttons.

This extends on my thoughts in a recent blog, Testing the UI without UI Testing in Swift.

    var body: some View {
        VStack {
            List(signalStore.all) { signal in
                SignalView(signal: self.signalStore.binded(signal: signal))
            }

Resetting NSUserDefaults in UI Testing

1. Add "UI-Testing" to launchArguments before launching the app under test
2. On launch, check for the argument in AppDelegate.swift
3. If it exists remove everything for the app's domain from NSUserDefaults
