Stub HTTP Request

XCTest

import Replacer
import TestReplacer 

class SampleTests: XCTestCase {
    func testJSONFile() {
        // register a stub
        self.urlStub.url("echo.jsontest.com").json(["test": "data"])
        
        // load sample.json & register a stub.
        self.urlStub.json(filename: "sample")

            let json = try! JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! [String: String]
            XCTAssert(json["test"] == "data")
            expectation.fulfill()
        }.resume()

        self.waitForExpectations(timeout: 0.02, handler: nil)

Quick & Alamofire

class SampleSpecs: QuickSpec {
    override func spec() {
        describe("Quick compatibility test") {
            context("using JSON file") {
                beforeEach() {
                    // wait for 1.5s
                    self.urlStub.url("echo.jsontest.com/[a-z]+/.*")
                        .httpMethod(.post)
                        .json(["test": "data"])
                        .delay(1.5)
                }

                it("returns mock data") {
                    var json: [String: String]?

                    Alamofire.request("http://echo.jsontest.com/key/value/one/two", method: .post).responseJSON { response in
                        json = response.result.value as? [String: String]
                    }

					// SessionManager is also OK.
					// SessionManager.default.request("http://echo.jsontest.com/key/value/one/two").responseJSON { _ in }

                    expect(json?["test"]).toEventually(equal("data"))
                }
            }
        }
    }
}

Method Swizzling

import UIKit
import Replacer

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        Replacer.replaceInstance(#selector(UIViewController.viewWillAppear(_:)),
                                 of: UIViewController.self,
                                 with: #selector(UIViewController.orig_viewWillAppear(_:)),
                                 of: UIViewController.self)

        return true
    }
}

extension UIViewController {
    func orig_viewWillAppear(_ animated: Bool) {
        orig_viewWillAppear(animated)

        print("swizzled")
    }
}
