I am attempting to unit test my emailing functionality using the smtpd package. This package allows the use of a debug server.
When I run this test using pytest it produces an error during collection:
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/smtpd.py:646: in __init__
type=socket.SOCK_STREAM)
E TypeError: getaddrinfo() got an unexpected keyword argument 'type'
However if I run this test using unittest, it manages to pass fine. Both of them are run inside the same virtual environment using Python3.6
This is the code I use to instantiate the debugging server and the test functions:
class DebuggingServer(smtpd.DebuggingServer):
def __init__(self, addr, port):
smtpd.DebuggingServer.__init__(self, localaddr=(addr, port), remoteaddr=None)
class DebuggingServerThread(threading.Thread):
def __init__(self, addr='localhost', port=1025):
threading.Thread.__init__(self)
self.server = DebuggingServer(addr, port)
def run(self):
asyncore.loop(use_poll=True)
def stop(self):
self.server.close()
self.join()
class TestMyEmail(unittest.TestCase):
server = DebuggingServerThread()
def setUp(self):
self.server.start()
print('Server has started')
def tearDown(self):
self.server.stop()
print('Server has stopped')
def test_png(self):
png_files = [os.path.join(DATA_DIR, 'page1.png'),
os.path.join(DATA_DIR, 'page2.png')]
with open(os.path.join(DATA_DIR, 'test_png.txt'), 'w+') as f:
with redirect_stdout(f):
success = myemail.mail(recipients=['email@email'],
message="Test email sent from server to test inline attachment of png files",
attachments=png_files,
subject="TestMyEmail.test_png")
with open(os.path.join(DATA_DIR, 'test_png.eml'), 'w+') as email_file:
gen = generator.Generator(email_file)
gen.flatten(success)
assert type(success)
if __name__ == "__main__":
unittest.main()
