示例1: NormalSource
it('endDrag() sees null as drop result if dropped outside a target', () => {
const source = new NormalSource()
const sourceId = registry.addSource(Types.FOO, source)
backend.simulateBeginDrag([sourceId])
backend.simulateEndDrag()
expect(source.recordedDropResult).toEqual(null)
})示例2: drop
it('ignores drop() if no drop targets entered', () => {
const source = new NormalSource()
const sourceId = registry.addSource(Types.FOO, source)
backend.simulateBeginDrag([sourceId])
backend.simulateDrop()
backend.simulateEndDrag()
expect(source.recordedDropResult).toEqual(null)
})示例3: beginDrag
it('lets beginDrag() be called again in a next operation', () => {
const source = new NormalSource()
const sourceId = registry.addSource(Types.FOO, source)
backend.simulateBeginDrag([sourceId])
backend.simulateEndDrag()
source.didCallBeginDrag = false
expect(() => backend.simulateBeginDrag([sourceId])).not.toThrow()
