test-lib module should export dispatchEvent #4177
Description
As of alpha-37 it is only available through 'angular2/src/test_lib/utils'
Maybe I'm missing a better technique but the way I know to trigger DOM events is through something like dispatchEvent. For example, I have test code that looks like this:
// get the HTML element and change its value in the DOM
var input = rootTC.query(By.css('input')).nativeElement;
input.value = "Dog Man"
dispatchEvent(input, 'change'); // event triggers Ng to update model
I think I stole it from one of the Angular core tests.
Alternative (perhaps better?), expose DOM so we can do it ourselves (and more) as in:
DOM.dispatchEvent(input, DOM.createEvent('change'));

dispatchEvent was not meant to be public api. it's an internal helper that leaked.
we should provide a more ergonomic way to trigger events post AngularConnect. in the meantime you can use regular dom apis to create and dispatch events. https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent
