使用 Appium 从 Mac 运行测试时无法在 webview 中执行触摸操作

Question

我被以下问题严重困扰，请帮助我找到一个可行的解决方案。

对于我得到的所有触摸动作

org.openqa.selenium.WebDriverException：未实现的命令：session/537d48a9dcdfb38a12ff318a302c9a08/touch/scroll 命令持续时间或超时：8 毫秒 构建信息：版本：'2.42.2'，修订：'6a6995d31c7c56c340d6f45a76976d43506cd6cc'，时间：'2014-06-03 10:52:47' 系统信息：主机：'Praveen-Prabhus-MacBook-Pro.local'，ip：'192.168.0.42'，os.name：'Mac OS X'，os.arch：'x86_64'，os.version：'10.9。 4'，java.version：'1.7.0_65' 会话 ID：bbe122fa-f325-4142-a555-9d2f4ea60e02 驱动信息：core.AppiumSwipeableDriver

     waitForVisible(By.xpath(OR.getProperty("btnTopUpMakePayment")),10);
     driver.findElement(By.xpath(OR.getProperty("btnTopUpMakePayment"))).click();
     return true;

     }catch(Exception e){
     ReportTest.error(e.getMessage());
     return false;
     }

我也尝试过 AppiumDriver - TouchAction，这给了我

org.openqa.selenium.UnsupportedCommandException：未知命令：session/9e5f0b55fdfb2c98dd019f44a7bf9c8a/touch/perform

我已经在 Windows 机器上成功运行了上面显示的相同脚本，但现在我已将我的项目移动到 MAC 并且在它没有按预期运行之后。

请帮我解决这个问题

实际上现在 webview 不支持 Touch Actions。但是有一些解决方法可用；我将通过一个 longpress 示例来展示它：我正在使用 Pointoption，因为我将获取元素的坐标并将其用于 longpress。

public void longpress(PointOption po) {
   //first you need to switch to native view
    driver.switchToNativeView();
    TouchAction action = new TouchAction((PerformsTouchActions) driver);
    action.longPress(po).waitAction(WaitOptions.waitOptions(Duration.ofSeconds(2)));
    action.release();
    action.perform();
    driver.switchToDefaultWebView();
}

为了得到我在methood下设计的元素的坐标

public PointOption getElementLocation(WebElement element) {
    int elementLocationX;
    int elementLocationY;

    //get element location in webview
    elementLocationX = element.getLocation().getX();
    elementLocationY = element.getLocation().getY();

    //get the center location of the element
    int elementWidthCenter = element.getSize().getWidth() / 2;
    int elementHeightCenter = element.getSize().getHeight() / 2;
    int elementWidthCenterLocation = elementWidthCenter + elementLocationX;
    int elementHeightCenterLocation = elementHeightCenter + elementLocationY;

    //calculate the ratio between actual screen dimensions and webview dimensions
    float ratioWidth = device.getDeviceScreenWidth() / ((MobileDevice) device)
            .getWebViewWidth().intValue();
    float ratioHeight = device.getDeviceScreenHeight() / ((MobileDevice) device)
            .getWebViewHeight().intValue();

    //calculate the actual element location on the screen , if needed you can increase this value,for example i used 115 for one of my mobile devices.
    int offset = 0;  


    float elementCenterActualX = elementWidthCenterLocation * ratioWidth;
    float elementCenterActualY = (elementHeightCenterLocation * ratioHeight) + offset;
    float[] elementLocation = {elementCenterActualX, elementCenterActualY};

    int elementCoordinateX, elementCoordinateY;
    elementCoordinateX = (int) Math.round(elementCenterActualX);
    elementCoordinateY = (int) Math.round(elementCenterActualY);
    PointOption po = PointOption.point(elementCoordinateX, elementCoordinateY);
    return po;
}

现在你有一个 longpress(PointOption po) 和 getElementLocation(Webelement element) 方法，它们为你提供了在 longpress 方法中使用的 po 值。现在一切准备就绪，您可以按如下方式使用它们..

longpress(getElementLocation(driver.findElement(By.id("the selector can be any of them(xpath,css,classname,id etc.)")));
