The issue I am having is getting Alamofire to work with the xcode UI Testing.
I have isolated the parts down as much as I can to try and identify where the issue might be, but still can't solve this one. With a new xcode project using swift, I can use Alamofire as expected with the main ViewController.swift and the func viewDidLoad() function okay, but when creating a UI Test, I am unable to use the same code in the func testExample() function.
Versions of tools used:
Xcode = 9.2(9C40b)
Swift = 4.0
cocoapods = 1.4.0
macOS = High Sierra Version 10.13.2 (17C205)
Alamofire = 4.5
ViewController.swift - Working okay
import UIKit
import Alamofire
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
Alamofire.request("https://httpbin.org/get").responseJSON { response in
print("Request: \(String(describing: response.request))") // original url request
print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)") // response serialization result
if let json = response.result.value {
print("JSON: \(json)") // serialized json response
}
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Data: \(utf8Text)") // original server data as UTF8 string
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
Result
Request: Optional(https://httpbin.org/get) Response: Optional( { URL: https://httpbin.org/get } { Status Code: 200, Headers { "Access-Control-Allow-Credentials" = ( true etc...
UITestExample() - Not Working
//
// exalamUITests.swift
// exalamUITests
//
import XCTest
import Alamofire
class exalamUITests: XCTestCase {
override func setUp() {
super.setUp()
// Put setup code here. This method is called before the invocation of each test method in the class.
// In UI tests it is usually best to stop immediately when a failure occurs.
continueAfterFailure = false
// UI tests must launch the application that they test. Doing this in setup will make sure it happens for each test method.
XCUIApplication().launch()
// In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this.
}
override func tearDown() {
// Put teardown code here. This method is called after the invocation of each test method in the class.
super.tearDown()
}
func testExample() {
Alamofire.request("https://httpbin.org/get").responseJSON { response in
print("Request: \(String(describing: response.request))") // original url request
print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)") // response serialization result
if let json = response.result.value {
print("JSON: \(json)") // serialized json response
}
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Data: \(utf8Text)") // original server data as UTF8 string
}
}
}
}

This Question was similar, but it is over a year old and I thought I could add more detail.
I'm new to Mac, swift, xcode, and cocoapods, but I have tried all similar S.O. related answers already and tried many different things. (Usually work in python and linux)
Any help would be very much appreciated.
Networking in Alamofire (as all other iOS networking libraries) is asynchronous. Your test is ending well before the request is even processed by the server. That's why your closure for responseJSON method is never fired. You have to use expectations to get it work: https://developer.apple.com/documentation/xctest/asynchronous_tests_and_expectations/testing_asynchronous_operations_with_expectations
I'm curious though, why do you need networking inside the UI test?
