const wrapper = mount(Foo)
const textInput = wrapper.find('input[type="text"]')
await textInput.setValue('some value')
expect(wrapper.find('input[type="text"]').element.value).toBe('some value')
const select = wrapper.find('select')
await select.setValue('option value')
expect(wrapper.find('select').element.value).toBe('option value')
// requires <select multiple>
const multiselect = wrapper.find('select')
await multiselect.setValue(['value1', 'value3'])
const selectedOptions = Array.from(multiselect.element.selectedOptions).map(
o => o.value
)
expect(selectedOptions).toEqual(['value1', 'value3'])
