A testsupport utility module for python
Project description
quiltz-testsupport
A package for test support
Purpose
At QWAN we're building some applications in python. We collect usefull stuff in quiltz packages:
- quiltz-domain contains domain level modules like, entity id's, results, an email anonymizer, validators and parsers
- quiltz-testsupport (this package) contains test support modules, that supports mainly non unit tests, like integrating with smtp, probing asynchronous results and asserting log statements
- quiltz-messaging contains a messaging domain concept and an engines to send the messages. Currently only smtp sending is supported.
modules in this packag
logging
With the logging module you can assert log statements in a test using the log_collector fixture:
in test:
from quiltz.testsupport import log_collector
def test_logs_hello(log_collector):
foo()
log_collector.assert_info('hello info')
in production
def foo():
logger = logging.getLogger()
logger.info('hello info')
probing
With the probing module you can probe for async results:
from hamcrest import assert_that, equal_to
from quiltz.testsupport import probe_that
def test_stub_server_collects_message_for_recepient(self):
message = aMessage(recipient='rob@mailinator.com', sender='no-reply@qwan.eu', subject='test', body='hello test')
self.message_engine.send([message])
probe_that(lambda: self.server.messages == [stringified_message(message)])
# or
probe_that(lambda: assert_that(self.server.messages, equal_to([
stringified_message(message)
])))
# or
probe_that(lambda: self.server.messages, equal_to([
stringified_message(message)
]))
smtp
With the smtp module you can create a stub smtp server that collects smtp messages
from hamcrest import assert_that, equal_to
from quiltz.testsupport import probe_that
def server()
server = StubSmtpServer(hostname='localhost', port=9925)
server.start()
yield(server)
server.stop()
def test_collects_message_for_recepient(self, server):
message_engine = SMTPClientForTest(host='localhost', port='9925')
message = aMessage(recipient='rob@mailinator.com', sender='no-reply@qwan.eu', subject='test', body='hello test')
message_engine.send([message])
probe_that(lambda: assert_that(server.messages, equal_to([
stringified_message(message)
])))
