示例1: async_it

const subscriptionSpy = jasmine.createSpy('subscriptionSpy');
const initialSubEmit = new Promise(resolve => subscriptionSpy.and.callFake(resolve));
push.subscription.subscribe(subscriptionSpy);
await initialSubEmit;
subscriptionSpy.calls.reset();
// Error due to no subscription.
await push.unsubscribe().catch(() => undefined);
