Question

我正在与Selenium进行一些测试，在此期间我发现了一些我不确定的奇怪行为......

似乎Move类的MoveToElement方法导致window.onmousemove事件反复触发，即使在鼠标移动完成后（这是我的问题以及我在这里发布的原因，而不是onmousemove行为时的行为）人类正在与浏览器进行交互。）

我希望onmousemove事件仅在鼠标实际移动时触发，就像它应该的那样。谢谢你的帮助。

这是我的代码。

Public Class Form1
Imports OpenQA.Selenium
Imports OpenQA.Selenium.IE
Imports OpenQA.Selenium.Interactions

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim driver As New InternetExplorerDriver()
        driver.Navigate.GoToUrl("http://127.0.0.1:1337/showmouseposition.html")
        driver.Keyboard.PressKey(Keys.F12)
        Dim builder As New Actions(driver)
        Dim ele As IWebElement = driver.FindElement(By.Id("myButton"))
        builder.MoveToElement(ele)
        builder.Perform()
    End Sub

End Class

        window.doLogging = true;

            // (This is to support old IE)
            if (event.pageX == null && event.clientX != null) {
                eventDoc = (event.target && event.target.ownerDocument) || document;
                doc = eventDoc.documentElement;
                body = eventDoc.body;

                event.pageX = event.clientX +

你尝试过build.perform（）吗？

 Public Class Form1
 Imports OpenQA.Selenium
 Imports OpenQA.Selenium.IE
 Imports OpenQA.Selenium.Interactions

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles 
    Button1.Click
    Dim driver As New InternetExplorerDriver()
    driver.Navigate.GoToUrl("http://127.0.0.1:1337/showmouseposition.html")
    driver.Keyboard.PressKey(Keys.F12)
    Dim builder As New Actions(driver)
    Dim ele As IWebElement = driver.FindElement(By.Id("myButton"))

    builder.MoveToElement(ele).Build.Perform()

End Sub

End Class

虽然这只是一个部分解决方案，但我使用FireFox驱动程序的正常onmousemove行为。因此，对于我的使用，我可以忍受不能使用具有可靠的onmousemove行为的IE（当我离开Selenium IE浏览器一夜之间导致导航到测试页面时，它实际上导致IE中的内存泄漏，该测试页面是console.logging onmousemove坐标而且泄漏是由于只有1次调用MoveToElement引起的，onmousemove是在无限循环中调用的，等等。）

但是，如果有人可以帮助我使用IE驱动程序，我会将你标记为答案，并会感谢你的帮助。我正在使用Seleniums站点的最新版本的IEServerDriver.exe，并在Windows 10上安装了IE 11。

即使鼠标不移动，Selenium MoveToElement也会引发onmousemove事件？
