问题
I'm writing some e2e tests and up until now I have been using the sleep(x) function to wait for ajax calls.
This is not very efficient as I must estimate the value to wait for testing and if I set too big a value then my tests are taking much more time then needed.
Is there a way to sleep for an ajax call duration? or at least when redirecting to a different page a way to sleep for the time the DOM is loaded?

If you do e2e testing with angular scenario runner and karma you do not need to worry about this. The framework handels all this for you. If you have a button that will cause your application to send an AJAX request and on response change something in the DOM, you can simply write your test like this:
element('#mybutton').click();
expect('...'); //Test that checks that the DOM has changed as excpected.
As long as you use angular full out, this will work.
