Testing for ui

[JanSafronov]

I am thinking about setting up testing for ui packages, will Jest framework be good enough for lens-up @Olszewskidev?
It has a few limitations with Vite so if it's ok I will configure babel for the ui packages?

#90 has an issue regarding import.meta property.
The error during testing reads:

Test suite failed to run

    packages/gallery-ui/src/services/GalleryApi.ts:6:14 - error TS1343: The 'import.meta' meta-property is only allowed when the '--module' option is 
'es2020', 'es2022', 'esnext', 'system', 'node16', or 'nodenext'.

I think adding the --experimental-vm-modules option to Jest testing command has partially resolved the issue but now there is a different error;

TypeError: Cannot read properties of undefined (reading 'VITE_GALLERY_SERVICE_URL')

I will just use Vitest, it seems like Jest isn't worth the setup since there are hurdles with Vite, ts and Jest..

I also want to mock getGalleryPhotos in the galleryApi together with "Cypress" SignalR JS testing library if this is fine @Olszewskidev
