单元测试接口生成器和故事板开发

Question

这种单元测试有意义吗？

func testPreferencesTabViewControllerNotNil() {
    var sb = NSStoryboard(name: "Main", bundle: nil)
    var window = sb?.instantiateControllerWithIdentifier("pref") as NSWindowController

    var tabs = window.window?.contentViewController as NSTabViewController
    XCTAssertNotNil(tabs, "Preferences window NSTabViewController must not be nil.")

}

func testPreferencesTabViewStyleIsToolBar() {
    var sb = NSStoryboard(name: "Main", bundle: nil)
    var window = sb?.instantiateControllerWithIdentifier("pref") as NSWindowController

    var tabs = window.window?.contentViewController as NSTabViewController
    XCTAssert(tabs.tabStyle == NSTabViewControllerTabStyle.Toolbar, "Preferences window NSTabViewController tab style must be Toolbar.")
}

func testFirstPreferencesTabViewIsGeneral() {
    var sb = NSStoryboard(name: "Main", bundle: nil)
    var window = sb?.instantiateControllerWithIdentifier("pref") as NSWindowController
    var tvc = window.window?.contentViewController as NSTabViewController
    var tvi = tvc.tabViewItems[0] as NSTabViewItem

    XCTAssert(tvi.viewController? is GeneralPreferencesViewController, "First Preferences Tab must be General Preferences")
    XCTAssert(tvi.label == "General" , "First Preferences Tab must have title ")

}

这主要是测试Interface Builder配置，那么，我们是否应该假设所有配置都是正确的？

在我看来，这看起来像是你在尝试验证和测试你的用户界面。我认为更好的方法是使用UIAutomation instrument。另外，我强烈建议您结合使用the brilliant tuneup_js library。
