我正在尝试使用ts-Jest/ Jest和Chai为我的Electron + Vue2应用程序添加测试，该应用程序使用TypeScript编写。然而，当我尝试运行简单的测试来确保Jest正常工作时，我现在遇到了一个问题，即Jest似乎不喜欢我导入要测试的组件的模板，如错误所示。当我尝试搜索与此相关的内容时，我没有太多的运气，并且很多指向“意外的令牌导入”，这是我已经解决的问题。
如果有人对如何使测试不会因导入HTML而出错有任何见解或知识，那将是很棒的，因为我被卡住了，文档似乎没有指向任何有用的东西。
错误信息：

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
