Question

我想测试一个已经存在的Vue-CLI 3项目。创建项目时，我尚未初始化测试预设。我已经搜索过，但是没有找到任何合适的结果。我也阅读了文档，但是它说在创建项目时要添加测试。

Answer 1

从项目根目录中，输入以下命令以添加@vue/test-utils and jest：

vue add @vue/unit-jest

命令输出应类似于以下内容：

$ vue add @vue/unit-jest

Answer 2

我成功使用了以下插件：

@ vue / cli-plugin-unit-jest（[https://www.npmjs.com/package/@vue/cli-plugin-unit-jest）

我使用以下命令从根文件夹安装了它：

vue add unit-jest

该命令已将条目添加到我的package.json文件中：

"scripts": {
    ...
    "test:unit": "vue-cli-service test:unit",
    ...
},

如何将带有Jest的Vue Test Utils添加到已经存在的Vue-CLI 3项目中？
