spyOn static Methods in jasmine tests

If you want to spy on a static method within your jasmine tests, you could do a simple spy like

beforeAll(async() =>{
  spyOn(UserService, "staticMethod").and.returnValue(true);
});

I'll tend to do this within beforeAll to avoid having problems when doing this in beforeEach. Within beforeEach you might end up in error messages like 

Error: <spyOn> : staticMethod has already been spied upon

I couldn't find something wrong with the test itself, but I noticed an strange import:

[async] from "q";

This was the reason for the strange error message. Correct import ist

[async] from "@angular/core/testing";
