async

npm Package @angular/core
Module import { async } from '@angular/core/testing';
Source core/testing/src/async.ts 
      
      function async(fn: Function): (done: any) => any;

Description

Wraps a test function in an asynchronous test zone. The test will automatically complete when all asynchronous calls within this zone are done. Can be used to wrap an inject call.

Example:

      
      it('...', async(inject([AClass], (object) => {
  object.doSomething.then(() => {
    expect(...);
  })
});
