@quasar/extras/mdi-v4 jest unit testing failing

[ymzhang23]

I am using the new SVG images. I have created a test for a header that contains a logo, name mdiMenu.

import { mdiMenu } from '@quasar/extras/mdi-v4'

But everything I am running the test: I always get this error:

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

Hello!
Correct transformation need to be configured.

 ...
 transform: {
    '^.+\\.jsx?$': require.resolve('babel-jest'),
 },
 ...

and ensure it is transformed

  transformIgnorePatterns: ['node_modules/(?!(quasar|quasar/*|@quasar|@quasar/*))'],
