- 使い方:
マウントされて描画された Vue コンポーネントを含む Wrapper
を生成します。
オプションなし:
import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
describe('Foo', () => {
it('renders a div', () => {
const wrapper = mount(Foo)
expect(wrapper.contains('div')).toBe(true)
})
})
Vue オプションを使用:
import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
describe('Foo', () => {
it('renders a div', () => {
const wrapper = mount(Foo, {
propsData: {
color: 'red'
}
})
expect(wrapper.props().color).toBe('red')
})
})
DOM へのアタッチ:
import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
describe('Foo', () => {
it('renders a div', () => {
const wrapper = mount(Foo, {
attachToDocument: true
})
expect(wrapper.contains('div')).toBe(true)
})
})

import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
import Bar from './Bar.vue'
import FooBar from './FooBar.vue'
describe('Foo', () => {
it('renders a div', () => {
const wrapper = mount(Foo, {
slots: {
default: [Bar, FooBar],
fooBar: FooBar, // <slot name="FooBar" /> と一致する,
foo: '<div />'
}
})
expect(wrapper.contains('div')).toBe(true)
})
})
グローバルプロパティのスタブ:
import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
describe('Foo', () => {
it('renders a div', () => {
const $route = { path: 'http://www.example-path.com' }
const wrapper = mount(Foo, {
intercept: {
$route
}
})
expect(wrapper.vm.$route.path).toBe($route.path)
})
})
コンポーネントのスタブ:
import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'
import Bar from './Bar.vue'
import Faz from './Faz.vue'
describe('Foo', () => {
it('renders a div', () => {
const wrapper = mount(Foo, {
stubs: {
Bar: '<div class="stubbed" />',
BarFoo: true,
FooBar: Faz
}
})
expect(wrapper.contains('.stubbed')).toBe(true)
expect(wrapper.contains(Bar)).toBe(true)
})
})
