angular - Angular：错误：超时 - 异步函数未在 5000 毫秒内完成（由 jasmine.DEFAULT_TIMEOUT_INTERVAL 设置）

Question

我正在使用bn-ng-idle角度模块来检测浏览器中是否有任何不活动。运行单元测试用例时会引发以下错误。我错过了什么吗？

Error: Timeout - Async function did not complete within 5000ms (set by jasmine.DEFAULT_TIMEOUT_INTERVAL)

app.module.ts

@NgModule({
  declarations: [AppComponent, AppHeaderComponent, VerticalSidebarComponent, AceComponent],
  imports: [BrowserModule, ...],
  providers: [BnNgIdleService], // BnNgIdleService service added here
  bootstrap: [AppComponent]
})
export class AppModule {}

app.component.ts

export class AppComponent implements OnInit {
  constructor(private bnIdle: BnNgIdleService) {}
  
   this.bnIdle.startWatching(3).subscribe(res => {
     if (res) {
        console.log("session expired");
        this.bnIdle.stopTimer();
      }
   });
}
