BaseWrapper.prototype.trigger has a bad implementation

[dima4p]

Subject of the issue

The method Vue#$emit accepts the name of the event an any number of the parameters that all being sent to the function - event handler.
But in test BaseWrapper.prototype.trigger accepts only one parameter after the event name.

Steps to reproduce

in the code:

<template lang='pug'>
my-component(@my_signal="my_signal")
</template>

<script>
…
 methods: {
  my_signal(...args) {
      console.log(args)
  }
},
…
</script>

in the test:

wrapper.find(…).trigger('my_signal', 1, 2)

Expected behaviour

it should be printed [1, 2]

Actual behaviour

it is printed [1]

Possible Solution

I think it is quite clear, there must be implemented the transfer of more than one argument.

BaseWrapper.prototype.trigger = function (eventString, ...args) {

trigger is designed to work with DOM events, as opposed to custom ones. Please see the documentation.

If you'd like to activate a custom event, how about:

wrapper.vm.$emit('customEvent', 1, 2, 3)

That will work!

No, it does not. I have a component "my-component", that emits a custom event "my_signal". Please write a test for the parent component using jest that function my_signal is called with 2 parameters when my-component emits the signal.
