Changing the initial import structure from: from .text_extraction_unit_tests import PrefixStrippingViewUnitTests
wrap_plus_module = sys.modules["Wrap Plus.wrap_plus"]
def run_unit_tests(unit_tests_to_run=[]):
runner = unittest.TextTestRunner()
classes = \
[
PrefixStrippingViewUnitTests,
SemanticLineWrapUnitTests,
LineBalancingUnitTests,
]
...to: wrap_plus_module = sys.modules["Wrap Plus.wrap_plus"]
def run_unit_tests(unit_tests_to_run=[]):
runner = unittest.TextTestRunner()
classes = \
[
sys.modules["Wrap Plus.tests.text_extraction_unit_tests"].PrefixStrippingViewUnitTests,
SemanticLineWrapUnitTests,
LineBalancingUnitTests,
]
...Seems to solved the problem. Now all the Unit Tests ran with success: |

I am not sure why, but I tried this fix on another package, and it did not worked. Then I searched and found this other solution by changing this: class ClearCursorsCaretsLastSelectionUnitTests(sys.modules["ClearCursorsCarets.tests.utilities"].BasicSublimeTextViewTestCase):To this: import os
import sys
import importlib
CURRENT_DIRECTORY = os.path.dirname( os.path.dirname( os.path.realpath( __file__ ) ) )
CURRENT_PACKAGE_NAME = os.path.basename( CURRENT_DIRECTORY ).rsplit('.', 1)[0]
utilities = importlib.import_module( CURRENT_PACKAGE_NAME + ".tests.utilities" )
class ClearCursorsCaretsLastSelectionUnitTests(utilities.BasicSublimeTextViewTestCase):
def test_1_selections_at_first_word(self):
pass |

I am not sure what you want to achieve. You need to make sure that the tests are organized such as they could be discovered by |

They are being discovered, the error was the importing of helper functions/classes from helper files. I had created an $ tree

Are you sure that the test cases are discoverable? AKAIK, unittest discover only search files named as EDIT: I saw that you have changed the pattern for discovery. |

I checked out your master branch: https://github.com/evandrocoan/Sublime-Wrap-Plus/tree/master and UnitTesting was working properly. EDIT: I just realized that you were talking about a different package. |
