Return an object containing custom events emitted by the `Wrapper` `vm`.

• Returns: { [name: string]: Array<Array<any>> }

• Example:

import { mount } from 'vue-test-utils'
import { expect } from 'chai'

const wrapper = mount(Component)

wrapper.vm.$emit('foo')
wrapper.vm.$emit('foo', 123)

/*
wrapper.emitted() returns the following object:
{
  foo: [[], [123]]
}
*/

// assert event has been emitted
expect(wrapper.emitted().foo).toBeTruthy()

// assert event count
expect(wrapper.emitted().foo.length).toBe(2)

// assert event payload
expect(wrapper.emitted().foo[1]).toEqual([123])

You can also write the above as follows:

// assert event has been emitted
expect(wrapper.emitted('foo')).toBeTruthy()

// assert event count
expect(wrapper.emitted('foo').length).toBe(2)

// assert event payload
expect(wrapper.emitted('foo')[1]).toEqual([123])
