示例1: it
it('should unsubscribe scheduled actions after execution', () => {
let subscribeSpy: any = null;
const counts: number[] = [];
const e1 = cold('a|');
const expected = '--a-(a|)';
const duration = time('-|');
const result = e1.pipe(
repeatWhen(notifications => {
const delayed = notifications.pipe(delay(duration, rxTestScheduler));
subscribeSpy = sinon.spy(delayed['source'], 'subscribe');
return delayed;
}),
skip(1),
take(2),
tap({
next() {
const [[subscriber]] = subscribeSpy.args;
counts.push(subscriber._subscriptions.length);
},
complete() {
expect(counts).to.deep.equal([1, 1]);
}
})
);
expectObservable(result).toBe(expected);
});示例2: higherOrder
export function repeatWhen<T>(this: Observable<T>, notifier: (notifications: Observable<any>) => Observable<any>): Observable<T> {
return higherOrder(notifier)(this) as Observable<T>;
