Requesting help for pytest and coverage

Development Python
1

I need help in testing at unit test level RIDE, to increase code coverage and have green status at SonarCloud :smile: .

I wrote a small Medium post to point to the GitHub project I have prepared to reproduce the problem and motivate programmers to help me.

Basically:

I am stuck at one test that validates the block of code which imports wxPython and should fail if there are problems with it.

This is the block to test:

try:
    import wx
    import wx.lib.inspection
except ModuleNotFoundError:
    print("ERROR: App cannot proceed, because wx is missing!")
    sys.exit(1)

And this is the code to test it (at least one of the many versions I tried):

import unittest
import pytest
from pytest import MonkeyPatch
import builtins

real_import = builtins.__import__


def myimport(name, globals, locals, fromlist, level):
    # DEBUG print(f"DEBUG: called myimport! name={name}")
    if name == 'wx.lib.inspection':
        raise ModuleNotFoundError  # real_import('wx_error', globals, locals, fromlist, level)
        # raise ImportError
    return real_import(name, globals, locals, fromlist, level)


class TestModule(unittest.TestCase):

    def tearDown(self):
        builtins.__import__ = real_import

    def test_missing_wx(self):
        with MonkeyPatch().context() as m:
            with pytest.raises((ModuleNotFoundError, SystemExit)):
                builtins.__import__ = myimport
                import myapp
                
                print(myapp.m1.VERSION)
                print(dir(myapp.m1))
