运行 使用 Jest 测试时的转译依赖
Transpile dependency when running tests with Jest
我在我的 Vue 应用程序中添加了对 tiptap-vuetify 的依赖,这反过来又添加了对其他 19 个模块的 t运行sitive 依赖。添加后,我 运行 我的测试得到了以下错误
Jest encountered an unexpected token
This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
Here's what you can do:
• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
• If you need a custom transformation specify a "transform" option in your config.
• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html
SyntaxError: Unexpected token 'export'
at ScriptTransformer._transformAndBuildScript (node_modules/@jest/transform/build/ScriptTransformer.js:537:17)
at ScriptTransformer.transform (node_modules/@jest/transform/build/ScriptTransformer.js:579:25)
at node_modules/tiptap-vuetify/dist/bundle-umd.js:1:112
at Object.<anonymous> (node_modules/tiptap-vuetify/dist/bundle-umd.js:1:2)
所以似乎 tiptap-vuetify 包含 Jest 需要 t运行spile 的代码。根据 Jest docs,如果 unt运行spiled 代码在 tiptap 或 tiptap-vuetify
中,将以下内容添加到 jest.config.js
应该可以解决问题
transformIgnorePatterns: [
"node_modules/(?!(tiptap-vuetify|tiptap)/)"
]
但没有任何区别。我添加了以下内容:
transformIgnorePatterns: ['/node_modules/tiptap.*']
并且问题不再出现,但我想我可能 运行 spiling 我的整个依赖关系树,因为现在 运行 测试需要更长的时间。有没有更好的方法来解决这个问题?
尽管有误导性的堆栈跟踪,tiptap-vuetify
并不是导致错误的实际模块。
错误很可能来自 vuetify
,如 Jest 错误的 Details

确保您的 transformIgnorePatterns
excludes vuetify
以确保它被转译:
// jest.config.js
module.exports = {
transformIgnorePatterns: ['/node_modules/(?!vuetify)'],
}
