示例1: makeHistory

const data = router(path);

}
),
(action: A<any>): boolean => action.type === goToType
),
({ data: path }: { data: string }) => history.go(path)
),
() => false // remove all
)
);
}示例2: expect
refSnapshotted.push('hello snapshot!', () => {

expect(data[0].val()).toEqual('hello snapshot!');
})
.subscribe(() => {
