在useDrag和useDrop中使用react-dnd进行测试

Question

有没有人能够使用带有useDrag和useDrop钩子的功能组件来测试https://github.com/react-dnd/react-dnd的拖放功能？

根据在http://react-dnd.github.io/react-dnd/docs/testing中找到的示例，它们要么使用DragSource装饰原始组件，要么使用DropTarget HOC装饰原始组件。例如：

// ...

export interface BoxProps {
    name: string

    // Collected Props
    isDragging: boolean
    connectDragSource: ConnectDragSource
}
const Box: React.FC<BoxProps> = ({ name, isDragging, connectDragSource }) => {
    const opacity = isDragging ? 0.4 : 1
    return (
        <div ref={connectDragSource} style={{ ...style, opacity }}>
            {name}
        </div>
    )
}

export default DragSource(
    ItemTypes.BOX,
    {
        beginDrag: (props: BoxProps) => ({ name: props.name }),
        endDrag(props: BoxProps, monitor: DragSourceMonitor) {
            const item = monitor.getItem()
            const dropResult = monitor.getDropResult()

            if (dropResult) {
                alert(`You dropped ${item.name} into ${dropResult.name}!`)
            }
        },
    },
    (connect: DragSourceConnector, monitor: DragSourceMonitor) => ({
        connectDragSource: connect.dragSource(),
        isDragging: monitor.isDragging(),
    }),
)(Box)

取自https://github.com/react-dnd/react-dnd/blob/master/packages/documentation/examples-decorators/src/01-dustbin/single-target/Box.tsx的示例

不过，我找不到任何使用它们的钩子的测试示例。他们确实有同时使用装饰器和钩子(https://github.com/react-dnd/react-dnd/tree/master/packages/documentation)的代码示例，但也有仅使用装饰器的测试示例。

我从github ticket上复制了这段代码，并为自己工作：

const dragAndDrop = (src: Element, dst: Element) => {
  fireEvent.dragStart(src);
  fireEvent.dragEnter(dst);
  fireEvent.drop(dst);
  fireEvent.dragLeave(dst);
  fireEvent.dragEnd(src);
 };
const allSections = rendered.getAllByRole('dropzone');

const marketSection = allSections[0];
const marketExpandedSection = allSections[1];

const basisIdDrag = within(marketSection).getByRole('draggable');

act(() => {
  dragAndDrop(basisIdDrag, marketExpandedSection);
});
