Executing an asynchronous test in Python

Question

I need to do the following test:

send a GET request to a server (http://remote/...)
wait for the server to send a POST request in response (http://local/...)
parse the POST data and do some assertions

Selenium does not fit this case: it can't listen to connections, and I can send a GET without Selenium as well.

so, I make a unit test:

class MobiMoneyTestCase(TestCase):
def test_can_send_response(self):
    resp = requests.post('http://url/api/', data={'callback': 'http://localhost:8000'})

    class Handler(SimpleHTTPRequestHandler):
        def do_GET(self):
            assert self.path == '...'

    httpd = SocketServer.ThreadingTCPServer(('localhost', 8000),Handler)

The test has to wait 5 seconds for the POST request and then fail if nothing happened. How can I merge these items in the test? If I put sleep(5) in the test_can..., the httpd handler does not reply until the countdown ends.

You are well beyond unittest teroritory and into integration testing. Use integration testing tools instead (Selenium, for example). — Martijn Pieters, Nov 02 '12 at 12:47
The other server also sends queries. I need a sort of HTTP server on my end too. — culebrón, Nov 02 '12 at 12:50

Basically you want to timeout a process if it's too long ? You should check out the signal module in that case.

There is an neat implementation (with decorator) here : Timeout function if it takes too long to finish

No. I need to do assert inside a spawned thread and raise AssertionError in the main function. – culebrón Nov 02 '12 at 17:23
