How to drag and drop one div onto another in Cypress test using cypress-drag-drop package?

问题

我正在尝试编写一个 Cypress 测试,将列A拖放到该网页上的列B - https://the-internet.herokuapp.com/drag_and_drop

我安装了@4tw/cypress-drag-drop包,并将以下内容添加到我的support/commands.js中:

require("@4tw/cypress-drag-drop");

以下是我的 Cypress 代码:

cy.get("#column-a").drag("#column-b", { force: true });

测试通过,但是在视觉上,列没有像在手动将列A拖放到列B上时那样表现出相同的行为。

相反,在 Cypress Explorer 中浏览器上出现了以下情况:

如您所见,列A被变灰,就好像被拖拽,但没有被释放。

请问有人能指出我做错了什么吗?

I am trying to write a Cypress test that drags & drops column A onto column B on this webpage - https://the-internet.herokuapp.com/drag_and_drop

I installed the @4tw/cypress-drag-drop package & added the following to my support/commands.js:
require("@4tw/cypress-drag-drop");

Here is my Cypress code:

cy.get("#column-a").drag("#column-b", { force: true });

The test passes, but the columns aren't behaving the same way visually as it does when I manually drag column A onto column B.

Instead, this is what appears on the browser in Cypress Explorer:

As you can see, column A is greyed out, as if it were dragged, but not dropped

无法翻译代码部分。以下是翻译好的文本:

"You cannot, the library does not support the correct events for this page.

But you can do it using Cypress commands.

These are the events used on the page:

  • "dragstart" 事件监听器的处理函数为 handleDragStart。
  • "dragenter" 事件监听器的处理函数为 handleDragEnter。
  • "dragover" 事件监听器的处理函数为 handleDragOver。
  • "dragleave" 事件监听器的处理函数为 handleDragLeave。
  • "drop" 事件监听器的处理函数为 handleDrop。
  • "dragend" 事件监听器的处理函数为 handleDragEnd。

This is the test that passes:

// 检查初始顺序
cy.get('div.column')
.then($cols => [...$cols].map(col => col.innerText.trim()))
.should('deep.eq', ['A', 'B']);

const dataTransfer = new DataTransfer;

cy.get("#column-a")
.trigger('dragstart', { dataTransfer });
cy.get("#column-b")
.trigger('dragenter')
.trigger('dragover', { dataTransfer })
.trigger('drop', { dataTransfer });
cy.get("#column-a")
.trigger('dragend');

// 检查新顺序
cy.get('div.column')
.then($cols => [...$cols].map(col => col.innerText.trim()))
.should('deep.eq', ['B', 'A']);

// 检查拖动透明度是否恢复
cy.get("#column-a").should('have.css', 'opacity', '1');
cy.get("#column-b").should('have.css', 'opacity', '1');"

英文:

col.addEventListener("dragstart", handleDragStart, false);
col.addEventListener("dragenter", handleDragEnter, false);
col.addEventListener("dragover", handleDragOver, false);
col.addEventListener("dragleave", handleDragLeave, false);

  .trigger('dragover', {dataTransfer})
  .trigger('drop', {dataTransfer})

  .trigger('dragend')

// check new order
cy.get('div.column')
  .then($cols => [...$cols].map(col => col.innerText.trim()))
  .should('deep.eq', ['B', 'A'])

// check drag opacity reverted back
cy.get("#column-a").should('have.css', 'opacity', '1')
cy.get("#column-b").should('have.css', 'opacity', '1')
