DeliciousRaspberryPi/MockFive - A Mocking Framework for Swift Unit Tests

MockFive allows you to make a single mock for a class or protocol. You can then configure instances of this mock with stubbed implementations. For any commonly used class, MockFive can offer a powerful means to satisfy Swift's strict typing system without sacrificing power. Because of Swift's strict typing, you must implement every method you intend to mock with calls to MockFive's stub().

// Optional types will return `nil` by default
func myFunc(arg1: Int, arg2: String) -> String? {
    return stub(identifier: "myFunc", arguments: arg1, arg2)

// Non-optional types require a default value
var customItem = MyCustomClass() // This may be changed later. stub will return new value
func myFunc() -> MyCustomClass {
    return stub(identifier: "myFunc") { customItem }

Pattern: Riblets vs. VIPER

Engineering the architecture behind Uber's new rider app

Not being held back by our extensive codebase and previous design choices gave us the freedom where we otherwise would have made compromises. The outcome is the sleek new app you see today, which implements a new mobile architecture across both iOS and Android. Read on to learn why we felt the need to create this new architecture pattern, called Riblets, and how it helps us reach our goals.

The platforms share:

Core architectureClass namesInheritance relationships between business logic unitsHow business logic is dividedPlugin points (names, existence, structure, etc.)Reactive programming chainsUnified platform components
Each Riblet is made up of one Router, Interactor, and Builder with its Component (hence the name), and optional Presenters and Views. The Router and Interactor handle the business logic, while the Presenter and View handle the view logic.


Stetho - A Chrome debug bridge for Android applications

Stetho is a sophisticated debug bridge for Android applications. When enabled, developers have access to the Chrome Developer Tools feature natively part of the Chrome desktop browser. Developers can also choose to enable the optional dumpapp tool which offers a powerful command-line interface to application internals.

WireMock is a flexible library for stubbing and mocking web services. Unlike general purpose mocking tools it works by creating an actual HTTP server that your code under test can connect to as it would a real web service.

It supports HTTP response stubbing, request verification, proxy/intercept, record/playback of stubs and fault injection, and can be used from within a unit test or deployed into a test environment.

Although it’s written in Java, there’s also a JSON API so you can use it with pretty much any language out there.
