I'm using Django (1.5.5), selenium (2.41.0), splinter (0.6.0) and phantomjs (1.9.7) for running live tests.
While the tests mostly work, every now and then (very often on CircleCI, less often in a local VM) they hang until either there's a timeout on CircleCI or I kill the runner manually (Ctrl-C ie. KeyboardInterrupt works).
This is how my base test class looks:
class SplinterTestCase(LiveServerTestCase):
@classmethod
def setUpClass(cls):
super(SplinterTestCase, cls).setUpClass()
# start phantom just once per class, to speed up tests
cls.phantom = splinter.Browser('phantomjs', load_images=False)
@classmethod
def tearDownClass(cls):
cls.phantom.quit()
super(SplinterTestCase, cls).tearDownClass()
def login(self, *args, **kwargs):
# perform a login using Django builtin "client", steal the session
# cookie and inject it to phantomjs, avoiding the need to do the
# login dance for each test
from django.conf import settings
cn = settings.SESSION_COOKIE_NAME
self.django_client.login(*args, **kwargs)
if cn in self.django_client.cookies:
self.client.driver.add_cookie({
'name': cn,
'value': self.django_client.cookies[cn].value,
'path': '/',
'domain': 'localhost'
})
def setUp(self):
# use phantom as the test client instead of Django's
super(SplinterTestCase, self).setUp()
self.django_client = self.client
self.client = self.phantom
def tearDown(self):
# this seems to help somewhat (decreases the number of timeouts), but
# doesn't solve it completely
self.client.visit('about:config')
super(SplinterTestCase, self).tearDown()
After Ctrl-C, this is the stacktrace I get:

A similar problem might've been discussed in Django with splinter and phantomjs is painfully slow as the original poster also mentioned "it just freezes until I am out of patience to wait for it to finish". The answer there mentioned to try to put phantomjs start/stop in class setup/teardown, which I did here, but it doesn't solve the problem.
Has anyone experienced a similar problem, and if you have, what are your workarounds?
