Create Unit test for toggle/show/hide( callback )

[mgol]

Originally reported by gnarf at: http://bugs.jquery.com/ticket/12821

This signature should result in an animated toggle/show/hide with the default duration. This has historically been the behavior, and we should test it and document it. See also  https://github.com/jquery/api.jquery.com/issues/167.

The signature should also hold true for fade* and slide*

Issue reported for jQuery 1.8.2

Rescheduling to 3.0.1.

Can I work on the issue?

I am pretty sure no one else is! Feel free!

@gnarf can you help me a little about what needs to be done? I can see that here it was reported that callback also results in animation. So should I be adding that in the documentation and creating unit tests for that check?

[gnarf]

The documentation does exist for it, because duration is optional in the signature, but it should be unit tested that when you call .toggle(fn) .show(fn) or .hide(fn) it results in a default duration animation.

Something along the lines of calling jQuery( ".some-hidden-element" ).toggle( function( p ) { callbackCalled = true; } ) then checking that callbackCalled isn't called, perhaps checking the state of the element is correct for a show/hide animation in it's first frame, then this.clock.tick(400) and check that callbackCalled and last frame.

This should probably be sufficient

@gnarf ok thanks. I will look into it.
