Unit Testing in Xcode, does it run the app?

Question

I\'m running into a strange problem that I haven\'t run into before.

When you do cmd+U to run your Unit Tests (OCUnit for example) does it actually call the main.m,

Answer 1

If you're using Swift (you probably don't have a main.c), you have to do these steps :

1: remove @UIApplicationMain in AppDelegate.swift

2: Create an empty TestingAppDelegate.swift

import UIKit
class TestingAppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
}

3: Create a file called main.swift :

import Foundation
import UIKit

let isRunningTests = NSClassFromString("XCTestCase") != nil

if isRunningTests {
   UIApplicationMain(C_ARGC, C_ARGV, nil, NSStringFromClass(TestingAppDelegate))
} else {
   UIApplicationMain(C_ARGC, C_ARGV, nil, NSStringFromClass(AppDelegate))
}
