Closes #10503 It is possible for code in `beforeEach` to capture and fork a zone (for example creating `NgZone` in `beforeEach`). Subsequently the code in `it` may chose to do `fakeAsync`. The issue is that because the code in `it` can use `NgZone` from the `beforeEach`. it effectively can escape the `fakeAsync` zone. A solution is to run all of the test in `ProxyZone` which allows a test to dynamically replace the rules at any time. This allows the `beforeEach` to fork a zone, and then `it` to retroactively became `fakeAsync` zone.
Angular Router
Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isn’t trivial.
The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
