JupyterHub R Kernel Test does not work

[Ruslan Korniichuk]

Hi all,

test_irkernel.py does not work. R Kernel works correct. test_execute_result does not work. Looks like test waiting on "[1] 6" result and get just "6". Any ideas how I can fix test_execute_result in fastest way?

[korniichuk@jupyter ~]$ python3 test_ipykernel.py
/usr/lib/python3.6/site-packages/jupyter_client/manager.py:77: DeprecationWarning: KernelManager._kernel_name_changed is deprecated in traitlets 4.1: use @observe and @unobserve instead.
  def _kernel_name_changed(self, name, old, new):

I think IRkernel changed since the example in this repo was written. IRkernel has similar tests using JKT, but it doesn't have a test_execute_result now:

@takluyver thank you very much for your extra fast answer and proposed link.
I'll test test_ir.py solution. Have a nice day.
