Hi, we need some help with a *compose ui test*.
We have a `LazyColumn`  and have been managed to follow the example <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/foundation/foundation/integration-tests/foundation-demos/src/main/java/androidx/compose/foundation/demos/LazyColumnDragAndDropDemo.kt|here> to implement the drag-and-drop operation for the list items.
In a compose UI test, we want to test the drag-and-drop behaviours using code below:
```            onNodeWithContentDescription("itemDesription", substring = true)
                .onChild()
                .performTouchInput {
                    down(bottomCenter)
                    moveTo(percentOffset(0.5f, -0.7f), delayMillis = 1000L)
                    up()
                }```
What the code would do:
1. Select an item from list (long-click)
2. Move the item one position up
However, the operation always fails with the step `moveTo`
So, we are wondering whether we are using the moveTo API properly.

Any suggestions?

Regards,

It looks like that the touch input is not kept down, when moving (dragging) is started.
