● Test suite failed to run

    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

尝试执行测试时。

这是我的jest.config.js：

module.exports = {
    ...require("@vue/cli-plugin-unit-jest/presets/typescript-and-babel/jest-preset"),
    transformIgnorePatterns: ['/node_modules/(?!(vuelayers|ol))'],
}

尝试使用不提供任何类型的 vuelayers..

使用 Jest 进行测试时出错：Vue 和 Typescript
