isVueInstance

Deprecation warning

isVueInstance is deprecated and will be removed in future releases.

Tests relying on the isVueInstance assertion provide little to no value. We suggest replacing them with purposeful assertions.

To keep these tests, a valid replacement for isVueInstance() is a truthy assertion of wrapper.find(...).vm.

Assert every Wrapper in WrapperArray is Vue instance.

  • Returns: {boolean}

  • Example:

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

const wrapper = mount(Foo)
const barArray = wrapper.findAll(Bar)
expect(barArray.isVueInstance()).toBe(true)
