jupyterlab / jupyterlab_server

I'd like to ask what is the point of having the test_data folder as a part of the main package. If I, as a user, install jupyterlab-server, I get this folder but it does not seem to be used anywhere outside tests that are not part of the main package.

Welcome to the Jupyter community! 🎉

I would say this is an old practice of packaging Python code with the ability for users to check the installation went well. Otherwise we need to provide two packages increasing the packaging maintenance burden.

~~But I agree that for the wheel we should exclude the folder.~~

Closing because we need those data files for the exported pytest plugin (I forget about it...)

Thank you very much for the quick response.
