MATLAB's test_run_interface FAILS

[dmartindeblas]

Summary

When launching the tests as explained here using the master branch of a just-forked nipype repository the test "nipype/interfaces/tests/test_matlab.py::test_run_interface" fails. The reason seems to be that the raised exception is a RuntimeError instead of the expected OSError:

nipype/nipype/interfaces/tests/test_matlab.py

Lines 104 to 107 in cd4c34d

	mc = mlab.MatlabCommand(script="foo;", paths=[tmpdir.strpath], mfile=True)
	assert not os.path.exists(default_script_file), "scriptfile should not exist 4."
	with pytest.raises(OSError):
	mc.run()

Actual behavior

Test "nipype/interfaces/tests/test_matlab.py::test_run_interface" fails since it raises a RuntimeError

Expected behavior

Test "nipype/interfaces/tests/test_matlab.py::test_run_interface" passes.

How to replicate the behavior

Running the tests as explained here using the master branch (commit: cd4c34d)

Specifications:

• OS: Ubuntu 20.04.3 LTS
• MATLAB version: 2021b (9.11.0.1769968) 64-bit (glnxa64)
• pytest version: 7.0.0

MATLABCMD enviroment variable was exported to the correct matlab executable

Execution environment

• My python environment outside container

Possible solution

I have replaced the line the OSError exception in line

nipype/nipype/interfaces/tests/test_matlab.py

Line 106 in cd4c34d

with pytest.raises(OSError):

with the RuntimeError exception and the tests is passing with my setup, but I ignore if this change will not work for other setups. Let me know if you want that I make a Pull Request.

Yes, that looks correct. It seems that we don't have any CI builds that install the MATLAB runtime. Please feel free to submit a PR.
