Features

• Saves full http request and responses
• Unit tests are easy - no more having to write a bunch of boilerplate code for the network layer
• Automated UI tests are easy too
• Audit responses
  1. Server side dev said they didn’t change anything but you can prove they did because you saved the responses
• Api not ready? That’s ok you can create your own stubs and use them until the api is ready
• Debug http requests - view requests being saved as responses are being consumed by your App
• Replay customer experiences -> need to upload to your server yourself

Requirements

• iOS 10.0+ / tvOS 11.0+
• Xcode 11.3+
• Swift 5.1+

Installation

Swift Package Manager (SPM)

dependencies: [
    .package(name: "StubPlay", url: "https://github.com/mokten/StubPlay.git", .upToNextMajor(from: "0.1.11"))
]

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

• Cocoapods 1.7+

$ gem install cocoapods

CocoaPods 1.7+ is required to build StubPlay

To integrate StubPlay into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'StubPlay'
end

Then, run the following command:

$ pod install

Carthage

• Carthage 0.33+

Cartfile

github "mokten/StubPlay"

Usage

We recommend enabling stubs as soon as possible - in your main.swift file or App delegate init()

By default: requests/response are saved in the caches/com.mokten.stubplay directory. Every time the app is run this directory will be cleared out.

Add a reference folder to your app. ie. "Stub/default", this is where your stubs will be read from

import StubPlay

// This will save all requests and responses to the app cache directory
// Start the app and navigate around
// Once you have completed your scenario then copy the files in the cache directory to your reading stub directory "Stub/default"
let config = StubConfig(folders: ["Stub/default"],
                        saveResponsesDirURL: FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!.appendingPathComponent("stubplay"),
                        skipSavingStubbedResponses: false,
                        validateResponseFile: false,
                        clearSaveDir: true,
                        bundle: Bundle(for: type(of: self) ,
                        isEnabledServer: true,
                        protocolURLSessionConfiguration: nil,
                        isLogging: true)
try StubPlay.default.start(with: config)

_ = UIApplicationMain(CommandLine.argc, CommandLine.unsafeArgv, NSStringFromClass(Application.self), NSStringFromClass(AppDelegate.self))

or

import UIKit
import StubPlay

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    override init() {
        super.init()
        do {
            // let config = StubConfig() // use default settings or else override them as follows
            let config = StubConfig(folders: ["Stub/default"],
                                    saveResponsesDirURL: FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!.appendingPathComponent("stubplay"),
                                    skipSavingStubbedResponses: false,
                                    validateResponseFile: false,
                                    clearSaveDir: true,
                                    bundle: Bundle.main,
                                    isEnabledServer: true,
                                    protocolURLSessionConfiguration: nil,
                                    isLogging: true)
            try StubPlay.default.start(with: config)
        } catch {
            print(error)
        }
    }
    ...
}

Optionally, all requests are saved to the Caches directory (this can be turned off with configuration):

ie: ~/Library/Developer/CoreSimulator/Devices/C62F6E5A-6459-45B6-B20B-B7C8E07AA529/data/Containers/Data/Application/1C1E61F8-B7B9-45FA-AA7E-7928E8952989/Library/Caches/com.mokten.stubplay

Concepts

1. Stubbed request / response has 2 files
2. request+response/rewrite rule file -> json format
3. response body file -> native format

The response body is in its own file so that it can be easily be used by viewers/editers ie. image, json, text, html, videos
