html - Protractor 拖放 : Angular vs. Angular with HTML5

Question

我在我的 Protractor 测试中遇到了拖放问题(就像其他一些人一样)，但一般情况下不会出现问题 - 仅在使用 HTML5 的角度应用程序中。

为了演示，我使用两个演示拖放功能的网页编写了一个小 Protractor 测试套件。第一个页面(在第一个测试用例中使用)演示了 AngualarJS 中 jQueryUI 拖放功能的实现。这个工作得很好。第二页(在第二个测试用例中使用)使用带有 HTML5 的 Angular 拖放。这个在我的测试中不起作用。

我的下一个尝试是使用这个帖子也给我带来的辅助函数:https://gist.github.com/druska/624501b7209a74040175不幸的是，正如我的第三次测试显示的那样，这对我来说更晚了

谁能告诉我为什么拖放在 HTML 5 中不起作用，我必须做些什么才能让它运行？

提前致谢

我遇到了同样的问题，各种 dnd 模拟库似乎不适用于 angular-drag-and-drop-lists。

最后我 fork 了html-dnd简单地添加一个 dragover 事件，angular-drag-and-drop-lists 需要一些东西，因为它计算通过 dragover 事件放置的元素的索引。它还粘在一个临时 li 元素中，代码在删除它之前将其用作实际放置点。这就是用户在屏幕上看到的移动列表点。

fork 在 forked html-dnd .我通过 git pull 将其包含在我的 package.json 文件中的依赖项中

"html-dnd": "git://github.com/PloughingAByteField/html-dnd.git"

用于 Protractor

// at the top of the spec
var dragAndDrop = require('html-dnd').code;

<snip>

it('should dragover and drop', function() {
  var draggable = browser.findElement(by.id('id1'));
  var droppable = browser.findElement(by.id('id2'));
  browser.driver.executeScript(dragAndDrop, draggable, droppable);
);

更新:html-dnd 项目已合并到 dragover 事件中，因此您可以使用它来代替我未维护的分支。
