update()

Force root Vue component to re-render.

If called on a Wrapper containing a vm, it will force the Wrapper vm to re-render.

• Example:

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

const wrapper = mount(Foo)
expect(wrapper.vm.bar).toBe('bar')
wrapper.vm.bar = 'new value'
wrapper.update()
expect(wrapper.vm.bar).toBe('new value')
