我正在尝试验证我存储的两个项目是否相同。但是,在测试时,我在检查Date属性时遇到错误。

注意:我的Item类实现了Equatable协议。

这是我的setUp方法:

class InputViewControllerTests: XCTestCase {

    var sut: InputViewController!
    var placemark: MockPlacemark!

    override func setUp() {
        super.setUp()
        let storyboard = UIStoryboard(name: "Main",
                                      bundle: nil)
        sut = storyboard
            .instantiateViewController(
                withIdentifier: "InputViewController")
            as! InputViewController
        _ = sut.view
    }
}

这是我的测试类的扩展:

extension InputViewControllerTests {
    class MockGeocoder: CLGeocoder {
        var completionHandler: CLGeocodeCompletionHandler?
        override func geocodeAddressString(
            _ addressString: String,
            completionHandler: @escaping CLGeocodeCompletionHandler) {
            self.completionHandler = completionHandler
        }
    }

    class MockPlacemark : CLPlacemark {
        var mockCoordinate: CLLocationCoordinate2D?
        override var location: CLLocation? {
            guard let coordinate = mockCoordinate else
            { return CLLocation() }
            return CLLocation(latitude: coordinate.latitude,
                              longitude: coordinate.longitude)
        }
    }
}

这是我的测试:

func test_Save_UsesGeocoderToGetCoordinateFromAddress() {
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "MM/dd/yyyy"
        let timestamp = 1456095600.0
        let date = Date(timeIntervalSince1970: timestamp)
        sut.titleTextField.text = "Foo"
        sut.dateTextField.text = dateFormatter.string(from: date)
        sut.locationTextField.text = "Bar"
        sut.addressTextField.text = "Infinite Loop 1, Cupertino"
        sut.descriptionTextField.text = "Baz"
        let mockGeocoder = MockGeocoder()
        sut.geocoder = mockGeocoder
        sut.itemManager = ItemManager()
        sut.save()
        placemark = MockPlacemark()
        let coordinate = CLLocationCoordinate2DMake(37.3316851,
                                                    -122.0300674)
        placemark.mockCoordinate = coordinate
        mockGeocoder.completionHandler?([placemark], nil)
        let item = sut.itemManager?.item(at: 0)
        let testItem = ToDoItem(title: "Foo",
                                itemDescription: "Baz",
                                timestamp: timestamp,
                                location: Location(name: "Bar",
                                                   coordinate: coordinate))
        XCTAssertEqual(item, testItem)
    }

这是save()方法的实现:

class InputViewController: UIViewController {
    // ...
    @IBAction func save() {
        guard let titleString = titleTextField.text,
            titleString.characters.count > 0 else { return }
        let date: Date?
        if let dateText = self.dateTextField.text,
            dateText.characters.count > 0 {
            date = dateFormatter.date(from: dateText)
        } else {
            date = nil
        }
        let descriptionString = descriptionTextField.text
        if let locationName = locationTextField.text,
            locationName.characters.count > 0 {
            if let address = addressTextField.text,
                address.characters.count > 0 {
                geocoder.geocodeAddressString(address) {
                    [unowned self] (placeMarks, error) -> Void in
                    let placeMark = placeMarks?.first
                    let item = ToDoItem(
                        title: titleString,
                        itemDescription: descriptionString,
                        timestamp: date?.timeIntervalSince1970,
                        location: Location(
                            name: locationName,
                            coordinate: placeMark?.location?.coordinate))
                    self.itemManager?.add(item)
                }
            }
        }
    }
}

我无法弄清楚这有什么问题。我得到的错误是:

  

test_Save_UsesGeocoderToGetCoordinateFromAddress()]失败:XCTAssertEqual失败:("可选(ToDo.ToDoItem(标题:" Foo",itemDescription:可选(" Baz"),时间戳:可选(1456030800.0),位置:可选(ToDo.Location(名称:"栏",坐标:可选(__ C.CLLocationCoordinate2D(纬度:37.331685100000001,经度:-122.03006739999999)))))" )不等于("可选(ToDo.ToDoItem(标题:" Foo",itemDescription:可选(" Baz"),时间戳:可选(1456095600.0),位置:可选(ToDo.Location(名称:"栏",坐标:可选(__ C.CLLocationCoordinate2D(纬度:37.331685100000001,经度:-122.03006739999999))))))") -

可以清楚地看到,问题是两者的时间戳不一样,我不知道它为什么会改变。

编辑:正如@ganzogo发现的那样,这个项目之间的差异恰好是18个小时。我住在厄瓜多尔,这是GTM-5。也许这可以解决问题。

2 个答案:

答案 0 :(得分:1)

你的行后:

let dateFormatter = DateFormatter()

试试这个:

dateFormatter.timeZone = TimeZone(secondsFromGMT: 64800)

如果不起作用,请尝试:

dateFormatter.timeZone = TimeZone(secondsFromGMT: -64800)

: - )

但如果你只是在通行证中进行黑客攻击,那么你就有点打败单位测试的目的。您真的需要了解testItemitem现在是否表现出正确的行为,这取决于您的申请。

在func中 test_Save_UsesGeocoderToGetCoordinateFromAddress() 然后将时间戳转换为sut.dateTextField.text 在sut.save() sut.dateTextField.text 转换为时间戳,分钟和秒钟都会下降
