Resolve:

@LeeLenaleee can you add another (the one you described here: #10552 (comment))?

I'd call this "react" or "react-browser" instead of "web" (in case we need to test different platforms)

Maybe we also want to remove the "package-lock.json" so we always test with latest? (the one from node project needs to be removed for sure)
Also the .gitignore is a bit redundant because the tests are run in a temporary folder.

Not sure if removing package-lock.json is a good idea, then we can run into issues where the test fails because the lib updated. If an unexpected bug comes in and break things that should not break the tests. I reckon the chance is low this will happen but it might be worth considering. After seeying what happend with our own package lately and how it broke the helpers import.

But removing it will indeed remove some maintance that will be caused because of needed updates.

Not sure what is the better tradeoff

I think the solution to the package-lock.yaml issue would be to use pnpm. That would allow you to use the workspace version of Chart.js while using locked versions of all other dependencies
