Reactjs 如何模拟木偶戏中的拖放动作？

我在应用程序中使用了React DnD（拖放）。我想测试一下E2E

我想要模拟的是拖动一个特定的元素并将其放到一个特定的位置。我该怎么做

我得到的是：

//test.js
const mouse = page.mouse;
await mouse.down();
await mouse.move(126, 19);
await page.waitFor(400);

---

使用此代码，选择完成，但拖动不起作用。我应该如何实现这一点？

以下方法将允许您在Puppeter中模拟拖放动作：

const example = await page.$('#example');
const bounding_box = await example.boundingBox();

await page.mouse.move(bounding_box.x + bounding_box.width / 2, bounding_box.y + bounding_box.height / 2);
await page.mouse.down();
await page.mouse.move(126, 19);
await page.mouse.up();

---

以下是我在《木偶演员》中用于拖放的片段：

//This assumes only one element will be found for selectors you provide, otherwise there's ambiguity on which element was selected.
//In my code I'm throwing on more than 1 element found

async dragAndDrop(page, originSelector, destinationSelector) {
  await page.waitForSelector(originSelector)
  await page.waitForSelector(destinationSelector)
  const origin = await page.$(originSelector)
  const destination = await page.$(destinationSelector)
  const ob = await origin.boundingBox()
  const db = await destination.boundingBox()
    
  console.log(`Dragging from ${ob.x + ob.width / 2}, ${ob.y + ob.height / 2}`)
  await page.mouse.move(ob.x + ob.width / 2, ob.y + ob.height / 2)
  await page.mouse.down()
  console.log(`Dropping at   ${db.x + db.width / 2}, ${db.y + db.height / 2}`)
  await page.mouse.move(db.x + db.width / 2, db.y + db.height / 2)
  await page.mouse.up()
}

请注意，仍然实现了对Puppeter中拖放的支持。

没有一个特定于Puppeter的解决方案适合我，因此我最终将本机javascript写入一个文件，并将其导入Puppeter（在我的例子中是Jest）

拖放.js

async function dragAndDrop(source, target) {
  await page.evaluate((source, target) => {
    source = document.querySelector('#'+source);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("mousedown", true, true, null);
    event.clientX = source.getBoundingClientRect().top;
    event.clientY = source.getBoundingClientRect().left;
    source.dispatchEvent(event);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("dragstart", true, true, null);
    event.clientX = source.getBoundingClientRect().top;
    event.clientY = source.getBoundingClientRect().left;
    source.dispatchEvent(event);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("drag", true, true, null);
    event.clientX = source.getBoundingClientRect().top;
    event.clientY = source.getBoundingClientRect().left;
    source.dispatchEvent(event);


    target = document.querySelector('#'+target);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("dragover", true, true, null);
    event.clientX = target.getBoundingClientRect().top;
    event.clientY = target.getBoundingClientRect().left;
    target.dispatchEvent(event);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("drop", true, true, null);
    event.clientX = target.getBoundingClientRect().top;
    event.clientY = target.getBoundingClientRect().left;
    target.dispatchEvent(event);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("dragend", true, true, null);
    event.clientX = target.getBoundingClientRect().top;
    event.clientY = target.getBoundingClientRect().left;
    target.dispatchEvent(event);
  }, source, target);
}

const dragAndDrop = require('./drag-and-drop')

describe('when dragging and dropping todo', () => {

  it('should change order on DOM', async () => {
    const firstTodo = await page.evaluate(() => document.querySelectorAll('.input-container .input')[0].id);
    const secondTodo = await page.evaluate(() => document.querySelectorAll('.input-container .input')[1].id);

    dragAndDrop(firstTodo, secondTodo);

    const newFirstTodo = await page.evaluate(() => document.querySelectorAll('.input-container .input')[0].id);
    const newSecondTodo = await page.evaluate(() => document.querySelectorAll('.input-container .input')[1].id);

    expect(newFirstTodo).toEqual(secondTodo)
    expect(newSecondTodo).toEqual(firstTodo)
  });
});

test.js

async function dragAndDrop(source, target) {
  await page.evaluate((source, target) => {
    source = document.querySelector('#'+source);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("mousedown", true, true, null);
    event.clientX = source.getBoundingClientRect().top;
    event.clientY = source.getBoundingClientRect().left;
    source.dispatchEvent(event);

    event = document.createEvent("CustomEvent");
    event.initCustomEvent("dragstart", true, true, null);
    event.clientX = source.getBoundingClientRect().top;
    event.clientY = source.getBoundingClientRect().left;
    source.dispatchEvent(event);

    event = document.createEvent("CustomEvent");

    target.dispatchEvent(event);
  }, source, target);
}

const dragAndDrop = require('./drag-and-drop')

比内置的木偶演员功能稍微多一些，但希望这是一个足够简单的复制和粘贴解决方案，适用于需要更多拖放控制的任何其他人。

您是否正在寻找类似的解决方案，但它不适用于我。您尝试过吗？是的。但这也没有解决我的问题issue@Khushi有什么最新消息吗？你解决了这个问题吗？clientX和clientY被替换为getBoundingClientRect（）。顶部和左侧，但一旦我解决了这个问题，这对我很有效，谢谢！！
