You patch Processor
in test_write_and_parse()
but it's instantiated in DocParser.__init__()
which is called from setUp()
.
This should work, though I haven't tested it:
class DocParserTests(unittest.TestCase):
def setUp(self):
self.mock_writer = MagicMock()
with patch('parser.docparser.Processor'):
self.docparser = docparser.DocParser(self.mock_writer)
@patch("parser.docparser.logger")
def test_write_and_parse(self, mock_logger):
products = "products"
self.docparser.write_and_parse(products)
I've used context manager instead of decorator to avoid changing setUp()
signature (adding an argument).
Also the order of mock arguments for test_write_and_parse() is incorrect in your code. Here's an excerpt from mock docs:
When you nest patch decorators the mocks are passed in to the decorated function in the same order they applied (the normal python order that decorators are applied). This means from the bottom up...
Correct order:
@patch("parser.docparser.logger") # This seems to be patched properly
@patch("parser.docparser.Processor") # This is not patched
def test_write_and_parse(self, mock_proc, mock_logger):
# ...
Of cource, it doesn't really matter in your particular case because mock_proc
and mock_logger
are not used later.
