在 selenium 2 测试中可视化/显示鼠标光标位置（例如 PHPUnit Webdriver）

Question

我正在运行宁 \PHPUnit_Extensions_Selenium2TestCase 到运行测试移动鼠标并进行点击 ($this->moveto)。为了改进调试和查看体验，我想查看鼠标光标当前所在的位置。使用以上方法系统鼠标光标不移动

Answer 1

每次页面加载后执行 javascript 启用鼠标光标显示。

    /**
     * Enable mouse cursor display
     */
    protected function enableCursor()
    {
        $this->execute(array('script' => <<<EOF
        var seleniumFollowerImg=document.createElement("img");
        seleniumFollowerImg.setAttribute('src', 'data:image/png;base64,'
            + 'iVBORw0KGgoAAAANSUhEUgAAABQAAAAeCAQAAACGG/bgAAAAAmJLR0QA/4ePzL8AAAAJcEhZcwAA'
            + 'HsYAAB7GAZEt8iwAAAAHdElNRQfgAwgMIwdxU/i7AAABZklEQVQ4y43TsU4UURSH8W+XmYwkS2I0'
            + '9CRKpKGhsvIJjG9giQmliHFZlkUIGnEF7KTiCagpsYHWhoTQaiUUxLixYZb5KAAZZhbunu7O/PKf'
            + 'e+fcA+/pqwb4DuximEqXhT4iI8dMpBWEsWsuGYdpZFttiLSSgTvhZ1W/SvfO1CvYdV1kPghV68a3'
            + '0zzUWZH5pBqEui7dnqlFmLoq0gxC1XfGZdoLal2kea8ahLoqKXNAJQBT2yJzwUTVt0bS6ANqy1ga'
            + 'VCEq/oVTtjji4hQVhhnlYBH4WIJV9vlkXLm+10R8oJb79Jl1j9UdazJRGpkrmNkSF9SOz2T71s7M'

            + 'ONcpr3PrXy9VfS473M/D7H+TLmrqsXtOGctvxvMv2oVNP+Av0uHbzbxyJaywyUjx8TlnPY2YxqkD'
            + 'dAAAAABJRU5ErkJggg==');
        seleniumFollowerImg.setAttribute('id', 'selenium_mouse_follower');
        seleniumFollowerImg.setAttribute('style', 'position: absolute; z-index: 99999999999; pointer-events: none;');
        document.body.appendChild(seleniumFollowerImg);
jQuery(document).mousemove(function(e){
    jQuery("#selenium_mouse_follower").stop().animate({left:e.pageX, top:e.pageY});
});
EOF
        , 'args' => array()));
    }

这取决于 JQuery 在目标页面中加载 - 另一种解决方案，没有花哨的动画，也是可能的。

通过 Alex 的回答，我发现将他的 Javascipt 直接放入我的页面更容易。这是我最终得到的代码。感谢您的帮助。

function enableCursor()
{
 var seleniumFollowerImg=document.createElement("img");
 seleniumFollowerImg.setAttribute('src', 'data:image/png;base64,'
  + 'iVBORw0KGgoAAAANSUhEUgAAABQAAAAeCAQAAACGG/bgAAAAAmJLR0QA/4ePzL8AAAAJcEhZcwAA'

 document.body.appendChild(seleniumFollowerImg);
 jQuery(document).mousemove(function(e){
  jQuery("#selenium_mouse_follower").css('left', e.pageX);
  jQuery("#selenium_mouse_follower").css('top', e.pageY);
 });
};

这是@JordanW 的回答，但没有 JQuery:

function enableCursor() {
  var seleniumFollowerImg = document.createElement("img");
  seleniumFollowerImg.setAttribute('src', 'data:image/png;base64,'
    + 'iVBORw0KGgoAAAANSUhEUgAAABQAAAAeCAQAAACGG/bgAAAAAmJLR0QA/4ePzL8AAAAJcEhZcwAA'
    + 'HsYAAB7GAZEt8iwAAAAHdElNRQfgAwgMIwdxU/i7AAABZklEQVQ4y43TsU4UURSH8W+XmYwkS2I0'
    + '9CRKpKGhsvIJjG9giQmliHFZlkUIGnEF7KTiCagpsYHWhoTQaiUUxLixYZb5KAAZZhbunu7O/PKf'
    + 'e+fcA+/pqwb4DuximEqXhT4iI8dMpBWEsWsuGYdpZFttiLSSgTvhZ1W/SvfO1CvYdV1kPghV68a3'

    + 'dAAAAABJRU5ErkJggg==');
  seleniumFollowerImg.setAttribute('id', 'selenium_mouse_follower');
  seleniumFollowerImg.setAttribute('style', 'position: absolute; z-index: 99999999999; pointer-events: none; left:0; top:0');
  document.body.appendChild(seleniumFollowerImg);
  document.onmousemove = function (e) {
    document.getElementById("selenium_mouse_follower").style.left = e.pageX + 'px';
    document.getElementById("selenium_mouse_follower").style.top = e.pageY + 'px';
  };
};

enableCursor();

感谢大家分享！下面是让它在 NodeJS 中工作的示例：

将 showCursor.js 文件添加到 nightwatch 子树的 commands 目录中，并用以下代码片段填充它

exports.command = function() {
  return this.execute(function() {
    const mouse = document.createElement('img');
    mouse.setAttribute(
      'src',
      'data:image/png;base64,' +
        'iVBORw0KGgoAAAANSUhEUgAAABQAAAAeCAQAAACGG/bgAAAAAmJLR0QA/4ePzL8AAAAJcEhZcwAA' +
        'HsYAAB7GAZEt8iwAAAAHdElNRQfgAwgMIwdxU/i7AAABZklEQVQ4y43TsU4UURSH8W+XmYwkS2I0' +
        '9CRKpKGhsvIJjG9giQmliHFZlkUIGnEF7KTiCagpsYHWhoTQaiUUxLixYZb5KAAZZhbunu7O/PKf' +
        'e+fcA+/pqwb4DuximEqXhT4iI8dMpBWEsWsuGYdpZFttiLSSgTvhZ1W/SvfO1CvYdV1kPghV68a3' +
        '0zzUWZH5pBqEui7dnqlFmLoq0gxC1XfGZdoLal2kea8ahLoqKXNAJQBT2yJzwUTVt0bS6ANqy1ga' +
        'VCEq/oVTtjji4hQVhhnlYBH4WIJV9vlkXLm+10R8oJb79Jl1j9UdazJRGpkrmNkSF9SOz2T71s7M' +
        'SIfD2lmmfjGSRz3hK8l4w1P+bah/HJLN0sys2JSMZQB+jKo6KSc8vLlLn5ikzF4268Wg2+pPOWW6' +
        'ONcpr3PrXy9VfS473M/D7H+TLmrqsXtOGctvxvMv2oVNP+Av0uHbzbxyJaywyUjx8TlnPY2YxqkD' +
        'dAAAAABJRU5ErkJggg=='
    );
    mouse.setAttribute('id', 'selenium-mouse');
    mouse.setAttribute(
      'style',
      'position: absolute; z-index: 999999; pointer-events: none; left:0; top:0'
    );
    document.body.appendChild(mouse);
    document.onmousemove = function(e) {
      document.getElementById('selenium-mouse').style.left = e.pageX + 'px';
      document.getElementById('selenium-mouse').style.top = e.pageY + 'px';
    };
  }, []);
};

之后，您可以在任何有 browser 变量的地方访问它，即在您的测试用例中：

// Visit some page ...
browser.showCursor();
...
