testing pyqt application - Qwidget: must construct a qapplication before a qwidget

Question

I have a pyqt application and like to test scripts for testing this application.

I was able to build the qapplication during my standalone testing. Not sure how to c

Answer 1

A QApplication must be created before creating any widget since it handles the eventloop

import unittest
import same_label
import sys

from PyQt5.QtWidgets import QApplication

app = QApplication(sys.argv)


class Test(unittest.TestCase):
    def setUp(self):
        ex = same_label.Example()

    def tearDown(self):
        pass

    def testName(self):
        pass


if __name__ == "__main__":
    #import sys;sys.argv = ['', 'Test.testName']
    unittest.main()

In the following link there is an example: http://johnnado.com/pyqt-qtest-example/, another option is to use the pytest-qt package
