dataclass are not supported

[arkadyzalko]

@dataclass is a pretty good feature and unfortunatelly is not supported.

Line 171 in 9d62e9b

# Object with __init__ that carries required non-default arguments are not supported

Example

class ObjectMapperTest(unittest.TestCase):
    """
    Unit tests for the `ObjectMapper` module.
    """
    @dataclass
    class FromTestDataClass:
        a: int
        b: str

    @dataclass
    class ToTestDataClass:
        a: int
        b: str

    def test_mapping_creation_without_mappings_correct_using_dataclass(self):
        """ Test mapping creation without mappings with dataclass"""

        # Arrange
        from_class = FromTestClass()
        mapper = ObjectMapper()
        mapper.create_map(FromTestDataClass, ToTestDataClass)

        # Act
        result = mapper.map(FromTestDataClass(a=1, b='2'))

        # Assert
        self.assertTrue(isinstance(result, ToTestDataClass), "Target types must be same")
        self.assertEqual(result.name, from_class.name, "Name mapping must be equal")
        self.assertEqual(result, ToTestDataClass(a=1, b='2'), "Class instance must be equal")
