我正在使用新的SVG图像。我为一个包含徽标的标题创建了一个测试，名称为mdiMenu。
从"@quasar/extras/mdi-v4"导入｛mdiMenu｝但我运行测试的所有内容：我总是收到这个错误：
SyntaxError: Unexpected token 'export'
29 |
30 | <script>
> 31 | import { mdiMenu } from '@quasar/extras/mdi-v4'
Do somebody else have encounter this problem and how can I solve this?
This is the rest of the error message:
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

需要设置正确的转换。因此，您需要正确配置jest.config.js
...
transform: {
'^.+\.jsx?$': require.resolve('babel-jest'),
},
...
我的笑话配置正在扩展预设
preset: '@vue/cli-plugin-unit-jest/presets/typescript-and-babel',
它已经包括了这个转换，但也设置为不转换来自node_modules 的包
transformIgnorePatterns: ['/node_modules/'],
参考：https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-插件单元jest/presets/default/jest-preset.js
因此，在我的配置中，我已将模式更改为
transformIgnorePatterns: ['node_modules/(?!(quasar|quasar/*|@quasar|@quasar/*))'],
所以它忽略了除了类星体的之外的所有包
希望这个答案能帮助到别人：(
