[5.5] add assertDispatchedTimes for event fakes

[ekateiva]

Hey,

I find it useful to test how many times the event was dispatched. I exposed the method assertDispatchedTimes(), however you can pass ant int to assertDispatched() instead of a callback, so you can use Event::assertDispatched(SomeEvent::class, 3).

This is a change in a method signature and a breaking change.

Actually, there are no signature changes ;)

Actually, there are no signature changes ;)

There is, because the 2nd param's type signature has changed. There are just no static signature changes.

I am not sure why you count it as a breaking change. Actually, the param has not changed, just the new type of it was introduced. However, the functionality is 100% backwards compatible.

[GrahamCampbell]

The problem is that someone extending the class, overriding the method, now suddenly has to support more types for that parameter, and that is what's technically breaking here.

Those sort of breaking changes are common place in laravel's patch releases though, so I wouldn't bother with reverting or retargetting 5.6, unless someone is actually burnt bad by this.
