Question

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。

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

无法将'testProject.AboutViewController'（0x105b0ad30）类型的值转换为'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遇到这个问题，并能够在这里帮助我。

Answer 1

我遇到了同样的问题，解决方案是：

在测试目标中添加故事板Main和AboutViewController
将UIStoryboard(name: "Main", bundle:NSBundle.mainBundle())替换为 UIStoryboard(name: "Main", bundle: NSBundle(forClass: self.classForCoder))

这样，您将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。 Check this link for details

Answer 2

几分钟前我遇到了同样的问题。这是我如何解决它。

将故事板添加到测试目标
以这种方式加载视图控制器：

var storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle:NSBundle(forClass: self.dynamicType))

self.vc = storyboard.instantiateViewControllerWithIdentifier("gettingStartedView") as! MainViewController

self.vc.loadView()

希望这有帮助！

Answer 3

尝试一下行之有效

class VehicleListControllerSpecs: XCTestCase {

var listController: VehicleListController!

override func setUp() {
    super.setUp()
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "VehicleListController") as! VehicleListController
listController = vc
    _ = listController.view
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

func testListViewHasTableView() {
    XCTAssertNotNil(listController.tableView,"view doesnt has tableview")
}
}

单元测试从故事板中快速转换视图控制器不起作用
