在 Swift 中对我自己的 ViewController 进行单元测试时使用未声明的类型“ViewController"? [英] Use of undeclared type 'ViewController' when unit testing my own ViewController in Swift?

问题描述

我一直在尝试用 Swift 编写测试用例来测试我的 ViewController.但是，当我尝试在 XCTestCase 中实例化我自己的 ViewController 时，我得到 "Use of undeclared type 'ViewController' ".(ViewController 是我自己的 UIViewController 类的名字)

I have been trying to write test cases in Swift to test my ViewController. However, when I try to instantiate my own ViewController in a XCTestCase I get "Use of undeclared type 'ViewController' ". (ViewController is the name of my own UIViewController class)

有没有其他人遇到过这个问题?我正在使用 Xcode 6 beta 5

Has anyone else faced this issue before? I am using Xcode 6 beta 5

推荐答案

Swift 1

如果你没有使用框架，你也应该添加 ViewController.swift 文件的目标成员作为你的测试目标.选择类文件添加到目标，如图所示:

Swift 1

You should add ViewController.swift file's target membership also as your test target also if you are not using framework. Select class file add to target as shown in image:

或

如果您的 ViewController 在一个框架内:ViewController 类在不同的目标中并且您没有声明具有公共访问级别的类.默认情况下，类是内部的(可在目标内访问).如果您想访问它，请将其声明为公共并将方法或属性设为公共，即

If you are ViewController is within a framework : ViewController class is in different target and You are not declaring class with public access level. By default Classes are internal (Accessible within a target). Declare it as public and also make methods or properties as public if you want to access it i.e

public class ViewController: UIViewController {

    public var content: String!

    override public func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override public func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

Swift 2 更新

在您的测试目标中，只需使用 @testable 关键字导入您要测试的模块:

Swift 2 Update

In your test target, just import the module you want to test using the @testable keyword:

@testable import moduleToTest

您现在可以访问测试目标中的 public 和 internal 符号.

You can now access public and internal symbols in your test target.
