Add new test for pagination variables

[KrzysztofSikoraCodete]

I've just added test for paging request. The test could pass If the filtered variables result were less than 2. Now we have more than 1 even though we use pagination.

I checked session configuration and supportsVariablePaging, has true.

Any suggestions?

Great, I think this is a sufficient test case to work against on the kernel side. Could you please open an issue in https://github.com/jupyter-xeus/xeus-python/ and tag this issue there?

Cheers, @KrzysztofSikoraCodete!

Thanks @KrzysztofSikoraCodete for looking into this 👍

jupyter-xeus/xeus-python#246 should fix it.

Thanks @JohanMabille!

Awesome, thank you @JohanMabille!

Just re-triggered the tests and it looks like the conda tests are now passing with the latest xeus-python.

However the wheel is giving some errors: https://github.com/jupyterlab/debugger/pull/415/checks?check_run_id=612276325

See jupyter-xeus/xeus-python-wheel#54 for more context.

The JupyterLab jest tests patch the jupyter paths here: https://github.com/jupyterlab/jupyterlab/blob/36a8da4d6bffea0fd9992a4d88627cffb46fe6a0/jupyterlab/tests/test_app.py#L88-L93

With the data directory becoming something like /tmp/tmpgrqb54bk/jupyter_data.

Which is why we install the xpython spec explicitly in the tests here:

debugger/tests/run-test.py

Lines 15 to 25 in 247735d

	jest_app.install_kernel(
	kernel_name='xpython',
	kernel_spec={
	'argv': [
	'xpython',
	'-f', '{connection_file}'
	],
	'display_name': 'xpython',
	'language': 'python'
	}
	)

As discussed, let's disable the wheel tests for now and re-enable them in a separate PR.

Thanks!
