setProps(props)

• Arguments:

  • {Object} props

• Usage:

Sets Wrapper vm props and forces update.

Note the Wrapper must contain a Vue instance.

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

const wrapper = mount(Foo)
wrapper.setProps({ foo: 'bar' })
expect(wrapper.vm.foo).to.equal('bar')

You can also pass a propsData object, which will initialize the Vue instance with passed values.

// Foo.vue
export default {
  props: {
    foo: {
      type: String,
      required: true
    }
  }
}

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

const wrapper = mount(Foo, {
  propsData: {
    foo: 'bar'
  }
})

expect(wrapper.vm.foo).to.equal('bar')
