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: it
it('should not react to a plain end drag', () => {
backend.simulateBeginDrag([source]);
backend.simulateHover([target]);
backend.simulateEndDrag();
expect(component.dropped).toBeFalsy();
expect(component.endDrag).toBeTruthy();
fixture.detectChanges();
