JavaScript webdriver-selenium`mouseMove`在Chromium上不正确? [英] JavaScript webdriver-selenium `mouseMove` inaccurate on Chromium?

问题描述

通过NodeJ(protractor和selenium-webdriver)在Windows 10上针对嵌入式Chromium运行Chromedriver.

Running Chromedriver through NodeJs - protractor and selenium-webdriver - against an embedded Chromium on Windows 10.

使用getLocation似乎可以返回准确的位置，但是当我尝试让WebDriver将鼠标移动到那些位置时，鼠标不会到达那里-除非我将位置乘以约1.45.

It seems that using getLocation returns accurate positions, but when I try to have WebDriver move the mouse to those positions, the mouse doesn't get there -- unless I multiply the positions by about 1.45.

那肯定是不对的?

这是我多年来第一次使用Selenium，但是我敢肯定我以前没有这样做.

This is the first time I've used Selenium in years, but I'm sure I haven't had to do this before.

下面是代码的缩写，其中包含一些webdriver日志: 1.将鼠标移到某个元素上， 1.按下鼠标键， 1.稍等一下要测试的系统做出反应， 1.稍微移动一下要测试的系统的鼠标， 1.等一下 1.移至目标元素 1.释放鼠标按钮.

Below is an abbreviation of the code, with some of the webdriver log: 1. move the mouse to an element, 1. depress the mouse button, 1. wait a little for the system under to test to react, 1. move the mouse a little for the system under test, 1. wait a little, 1. move to a target element 1. release the mouse button.

只要我什么都没改变，并且只能垂直移动，代码就可以工作.

The code works, provided I change nothing, and only move vertically.

如果我垂直移动，则看不到任何效果.

If I move vertically, I see no effect.

如果我在一个Chromium窗口中两次运行代码，并在每次运行开始时加载测试文档，则第二次运行会在文档加载过程中挂起.

If I run code twice in one Chromium window, loading the test document at the start of each run, the second run hangs around document loading.

var destLocation,
    fromEl = $('elementA'),
    destEl = $('elementB');

destEl.getLocation()
    .then(() => {
      browser.driver.actions()
        .mouseMove( fromEl, {x: 10, y: 10} )
        // 09:56:37.222 INFO - Done: [mousemove: 5 true]
        .mouseDown( fromEl, {x: 10, y: 10} )
        // 09:56:37.230 INFO - Done: [mousedown: no args]
        .perform();
    })
    .then(() => {
      browser.sleep(400);
    })
    .then(() => {
      // Business logic requires this
      browser.driver.actions().mouseMove( fromEl, {x:15, y:15} )
        // 09:56:37.719 INFO - Done: [mousemove: 5 true]
        .mouseDown()
        // 09:56:37.726 INFO - Done: [mousedown: no args]
        .perform();
    })
    .then(() => {
      browser.sleep(400);
    })
    .then(() => {
      browser.driver.actions().mouseMove( $('body'), destLocation ).perform();
      // 09:56:38.209 INFO - Done: [mousemove: 9 true]
    })
    .then(() => {
      browser.sleep(200);
    })
    .then(() => {
      browser.driver.actions().mouseUp().perform();
      // 09:56:38.425 INFO - Done: [mouseup: nothing]
    });
