setSelected

Selects an option element and updates v-model bound data.

• Example:

import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'

test('setSelected demo', async () => {
  const wrapper = mount(Foo)
  const options = wrapper.find('select').findAll('option')

  await options.at(1).setSelected()

  expect(wrapper.find('option:checked').element.value).toBe('bar')
})

• Note:

When you try to set the value to state via v-model by option.element.selected = true; parentSelect.trigger('input'), v-model is not triggered. v-model is triggered by change event.

option.setSelected() is an alias of the following code.

option.element.selected = true
parentSelect.trigger('change')
