A software package may have Matlab and Python functions. Plain Matlab code can be included via Pytest for Matlab and GNU Octave. To test the Matlab functions from Pytest, create test_matlab.py:

This assumes the Matlab test script resides in the same directory as “test_matlab.py”.

NOTE: Be sure that Matlab “runtests()” actually picks up the desired tests. We do not want the Matlab output to say

Totals:
   0 Passed, 0 Failed, 0 Incomplete.
   0 seconds testing time.

Generally, Python __file__ is not robust for packages but one might relax that restriction for test files where a clear error will result.
