+# `createLocalVue()`
+
+- **返回值：**
+  - `{Component}`
+
+- **用法：**
+
+`createLocalVue` 返回一个 Vue 的类供你添加组件、混入和安装插件而不会污染全局的 Vue 类。
+
+可通过 `options.localVue` 来使用：
+
+```js
+import { createLocalVue, shallow } from 'vue-test-utils'
+import { expect } from 'chai'
+import Foo from './Foo.vue'
+
+const localVue = createLocalVue()
+const wrapper = shallow(Foo, {
+  localVue,
+  mocks: { foo: true }
+})
+expect(wrapper.vm.foo).toBe(true)
+
+const freshWrapper = shallow(Foo)
+expect(freshWrapper.vm.foo).toBe(false)
+```

+# `mount(component {, options}])`
+
+- **参数：**
+
+  - `{Component} component`
+  - `{Object} options`
+
+- **返回值：** `{Wrapper}`
+
+- **选项：**
+
+移步[选项](options.md)
+
+- **用法：**
+
+返回第一个 DOM 节点或匹配选择器的 Vue 组件的 [`Wrapper`](wrapper/README.md)。
+
+可使用任何有效的[选择器](selectors.md)。
+
+**Without options:**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+import Foo from './Foo.vue'
+
+describe('Foo', () => {
+  it('renders a div', () => {
+    const wrapper = mount(Foo)
+    expect(wrapper.contains('div')).toBe(true)
+  })
+})
+```
+
+**使用 Vue 选项：**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+import Foo from './Foo.vue'
+
+describe('Foo', () => {
+  it('renders a div', () => {
+    const wrapper = mount(Foo, {
+      propsData: {
+        color: 'red'
+      }
+    })
+    expect(wrapper.hasProp('color', 'red')).toBe(true)
+  })
+})
+```
+
+**固定在 DOM 上：**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+import Foo from './Foo.vue'
+
+describe('Foo', () => {
+  it('renders a div', () => {
+    const wrapper = mount(Foo, {
+      attachToDocument: true
+    })
+    expect(wrapper.contains('div')).toBe(true)
+  })
+})
+```
+**默认的和具名的插槽：**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+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, // 将匹配 `<slot name="FooBar" />`。
+        foo: '<div />'
+      }
+    })
+    expect(wrapper.contains('div')).toBe(true)
+  })
+})
+```
+
+**将全局属性存根：**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+import Foo from './Foo.vue'
+
+describe('Foo', () => {
+  it('renders a div', () => {
+    const $route = { path: 'http://www.example-path.com' }
+    const wrapper = mount(Foo, {
+      mocks: {
+        $route
+      }
+    })
+    expect(wrapper.vm.$route.path).toBe($route.path)
+  })
+})
+```
+
+**将组件存根：**
+
+```js
+import { mount } from 'vue-test-utils'
+import { expect } from 'chai'
+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, {
+      stub: {
+        Bar: '<div class="stubbed />',
+        BarFoo: true,
+        FooBar: Faz
+      }
+    })
+    expect(wrapper.contains('.stubbed')).toBe(true)
+    expect(wrapper.contains(Bar)).toBe(true)
