XCTest Swift - 如何更快或更精确地滑动？

Question

我在XCTest中使用Swift进行了测试,我正在尝试滑动一个Feed,直到满足条件.我正在使用它swipeUp(),但问题在于它的行为就像人类轻扫一样,并且当它放开时会有这种痛苦的动画减速.在减速动画完成之前,它不会再次尝试滑动.此外,该方法不带任何参数.我想看看是否有像葫芦或拍摄甚至机器人会咖啡那里有属性刷卡方法类似swipeUp(fast)或者swipeUp(medium)甚至是swipeUp(x0,y200).

这是我在代码中尝试做的事情:

    func scrollDownUntilYouFindSomething() {
    while !findingSomehting.exists {
        app.swipeUp()
    }
}

很简单,但XCUIApplication中的swipeUp()非常慢.我希望能够精确地滑动甚至通过坐标.我试图在XCTest UI测试中使用从Replicate pull获取的坐标方法进行刷新

但是当它进入循环时它同样缓慢.

我根据Bharathram C给出的优秀答案写了一个扩展名.

我发现它比XCUIElement.swipeUp()更温和一些

//  XCUIElement+GentleSwipe.swift

import Foundation
import XCTest

extension XCUIElement
{
    enum direction : Int {
        case Up, Down, Left, Right
    }

    func gentleSwipe(_ direction : direction) {
        let half : CGFloat = 0.5
        let adjustment : CGFloat = 0.25
        let pressDuration : TimeInterval = 0.05

        let lessThanHalf = half - adjustment
        let moreThanHalf = half + adjustment

        let centre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: half))
        let aboveCentre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: lessThanHalf))
        let belowCentre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: moreThanHalf))
        let leftOfCentre = self.coordinate(withNormalizedOffset: CGVector(dx: lessThanHalf, dy: half))
        let rightOfCentre = self.coordinate(withNormalizedOffset: CGVector(dx: moreThanHalf, dy: half))

        switch direction {
        case .Up:
            centre.press(forDuration: pressDuration, thenDragTo: aboveCentre)
            break
        case .Down:
            centre.press(forDuration: pressDuration, thenDragTo: belowCentre)
            break
        case .Left:
            centre.press(forDuration: pressDuration, thenDragTo: leftOfCentre)
            break
        case .Right:
            centre.press(forDuration: pressDuration, thenDragTo: rightOfCentre)
            break
        }
    }
}

是的,我们可以在Swift中进行基于坐标的滑动.我们可以使用pressForDuration(duration,thenDragToElement:XCElement)创建自己的滑动操作.请看下面的例子.

为此,我们需要

1. 视图中的参考元素.(在必须执行滑动操作的部分中选择一个,它不应该是可拖动的元素).
2. 关于参考元素的开始坐标.
3. 关于参考元素的结束坐标/ XCUIElement.

然后我们可以有一个类似于下面的函数(在Swift 3中)

func customSwipe(refElement:XCUIElement,startdelxy:CGVector,enddeltaxy: CGVector){
      let swipeStartPoint = refElement.coordinate(withNormalizedOffset: startdelxy)
      let swipeEndPoint = refElement.coordinate(withNormalizedOffset: enddeltaxy)
      swipeStartPoint.press(forDuration: 0.1, thenDragTo: swipeEndPoint)

}

如果startdelxy是(0.0,0.0)并且enddeltaxy是(0.0,-ve),则滑动将从refElement向上移动.如果enddeltaxy是(0.0,+ ve),则滑动将下降.这是因为我们的参考元素将是原点,X是+ ve向右,Y是+ ve低于我们的参考元素.从较小的Y值开始(比如-0.75)并根据需要进行更改.更多的差异,更长的刷卡.

的swipeStartPoint和swipeEndPoint可以用元件更换(如果这样的存在于图).通常,对于swipeEndPoint,我们可以在导航栏中搜索swipeUp操作的元素.此外,更改X可以在左右方向上为我们提供customSwipes.

至于刷卡的速度,我不知道任何可以刷卡比默认速率更快/更慢的API.

更新了 Swift 4 的第一个答案。

extension XCUIElement {
    enum Direction: Int {
        case up, down, left, right
    }

    func gentleSwipe(_ direction: Direction) {
        let half: CGFloat = 0.5
        let adjustment: CGFloat = 0.25
        let pressDuration: TimeInterval = 0.05

        let lessThanHalf = half - adjustment
        let moreThanHalf = half + adjustment

        let centre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: half))
        let aboveCentre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: lessThanHalf))
        let belowCentre = self.coordinate(withNormalizedOffset: CGVector(dx: half, dy: moreThanHalf))
        let leftOfCentre = self.coordinate(withNormalizedOffset: CGVector(dx: lessThanHalf, dy: half))
        let rightOfCentre = self.coordinate(withNormalizedOffset: CGVector(dx: moreThanHalf, dy: half))

        switch direction {
        case .up:
            centre.press(forDuration: pressDuration, thenDragTo: aboveCentre)
        case .down:
            centre.press(forDuration: pressDuration, thenDragTo: belowCentre)
        case .left:
            centre.press(forDuration: pressDuration, thenDragTo: leftOfCentre)
        case .right:
            centre.press(forDuration: pressDuration, thenDragTo: rightOfCentre)
        }
    }
}
