Issues on slots / urls props binding / how to call a function / how to test @input and @blur as wrapper.vm.xxxxxx

[patrickyue]

Hi, there
I have several qq here, need some help
#1 Slots
we could send a props. slots before as
{ default: '<div></div>'},

but this now will create a Vue warning to ask us to get a function call for better performance,as
{ default: () =>'<div></div>' }.
then, for the previous DOM search, the element inside that HTML code will fail now, as it will not be there anymore.

#2 urls binding issue
we have props as { altText: 'some test', url: 'some urls' }. this now will break the unit testing,
this will happen for both image as :src=url, and a as :href = url, not sure what do I miss...
but I if I change the key name from url to imageUrl, it works, what do I miss here?

#3 How I call a function directly now ?
If you have a function named unitTesting inside your component,
We can do wrapper.vm.unitTesting to call that function previously, now after the new update,
not sure how to call them as wrapper.vm.unitTesting will have type errors. and tried wrapper.setupState.unitTesting, it is not working

#4 How to testing a input element with @input and @blur events?
I tried almost everything, the event function does not get triggerred
tried the documentation one inside vue-utils. that's why I need #3 to be there

any help is welcome,

thanks in advance
