如何将带有 Jest 的 Vue Test Utils 添加到现有的 Vue-CLI 3 项目中？

Question

我想测试一个已经存在的 Vue-CLI 3 项目。我在创建项目时没有初始化测试预设。我已经搜索过，但没有找到任何合适的结果。我也看了文档，但是说在创建项目的时候要添加测试。

Answer 1

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

vue add unit-jest

命令输出应与此类似：

$ vue add 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)

我使用命令从根文件夹安装它：

vue add unit-jest

该命令已将一个条目添加到我的 package.json 文件中：

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