Angular 2中是否存在notifyWhenNoOutstandingRequests或等效项? [英] Does notifyWhenNoOutstandingRequests or an equivalent exist in Angular 2?

问题描述

我已经看到测试框架(例如Arquillian)使用它来检测何时可以使用Angular 1来检查dom.是否有等效的方法可以在Angular 2中进行此操作?

I have seen this used by test frameworks (for example, Arquillian) to detect when the dom is ready to be examined with Angular 1. Is there an equivalent way to do this in angular 2?

推荐答案

中的

onEventDone应该适用于此

在最终的onTurnDone回调之后立即通知订阅者，然后结束VM事件.

Notifies subscribers immediately after the final onTurnDone callback before ending VM event.

此事件对于验证应用程序状态(例如在测试中)很有用.

This event is useful for validating application state (e.g. in a test).
