Unit Test

This unit test work for the layer if it has been added or not and check its suitability

Test Layer Transaction -Qgis Project instance/Add map layer whether layer exist -try/except raise error if not exist could not pass unit test

Test Load Layer -Read the layer -If None could not pass unit test

Here is the all code that we implement:

class SaveAttributesTest(unittest.TestCase):
    """Test dialog works."""
    @classmethod
    def setUpClass(cls):
        cls.iface = get_iface()
    def setUp(self):
        """Runs before each test."""
        QgsProject.instance().clear()
        self.dialog = SaveAttributesDialog(None)
        self.attributes=SaveAttributes(get_iface())
        self.attributes.dlg=self.dialog
    def test_Layer(self):
        try:
                vlayer = QgsVectorLayer("TEST_LINE","line","memory")
                vlayer = QgsVectorLayer("TEST_LINE","point","memory")
                vlayer = QgsVectorLayer("TEST_LINE","polygon","memory")

        except:
                self.assertTrue(True==False)

    def test_Layer_Transaction(self):
        try:
                vlayer = QgsVectorLayer("TEST_LINE","line","memory")
                QgsProject.instance().addMapLayer(vlayer)

        except:
                self.assertTrue(True==False)       

    def test_load_layer(self): 
        path=os.path.dirname(os.path.realpath(__file__)) + "../../save_attributes/unittests/"                                               
        ds = ogr.Open(path+"c_beytepe.shp",0)
        self.assertTrue(ds==None)

    def tearDown(self):
        """Runs after each test."""
        self.dialog = None
