单元测试从故事板中快速转换视图控制器不起作用

问题描述

我写了下面的测试用例，它在swift 1.1中运行良好。但在1.2中它的突破。

I have written the below test case which worked fine in swift 1.1. But in 1.2 its breaking.

class AboutViewController_Tests: XCTestCase
{
//var storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: NSBundle(forClass: self.dynamicType)) // Used in swift 1.1

var storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle:NSBundle.mainBundle()) // Replaced this in swift 1.2
var aboutViewController:AboutViewController!

override func setUp()
{
super.setUp()
aboutViewController = storyboard.instantiateViewControllerWithIdentifier("AboutViewController") as! AboutViewController
aboutViewController.viewDidLoad()
XCTAssertNotNil(aboutViewController, "About not nil")
}
}

运行单元测试时出错

无法转换类型值'testProject.AboutViewController'（0x105b0ad30）到'testProjectTests.AboutViewController'（0x116e51d20）。

我已经做了足够的研究来解决这个问题。但无法做到这一点。我希望你们中的一些人能够解决这个问题并且能够在这里帮助我。

I have done enough research to resolve this issue. But couldn't able to do it. I hope some of you come across this problem and will able to help me here.

推荐答案

我遇到了同样的问题，解决方法是：

I had the same problem and solution is:

• 添加故事板主和 AboutViewController in test target


• 用$替换 UIStoryboard（名称：Main，bundle：NSBundle.mainBundle（）） b $ b UIStoryboard（名称：Main，包：NSBundle（forClass：self.classForCoder））

• Add storyboard Main and AboutViewController in test target
• Replace UIStoryboard(name: "Main", bundle:NSBundle.mainBundle()) with UIStoryboard(name: "Main", bundle: NSBundle(forClass: self.classForCoder))

这样你就可以加载故事板并从测试目标包中初始化控制器，而不是从主目标包中使用它。

This way you'll load storyboard and initialize controller from test target bundle, instead from using it from main target bundle.Check this link for details
