Class Export

export async(fn: Function) : (done: any) => any

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(...);
  })
});
