New description:
I created ''functional_tests'' directory with empty ''__init__.py'' and
''test_all.py'' containing following code:
{{{
from django.test import LiveServerTestCase
from selenium import webdriver
class DemoTest(LiveServerTestCase):
def test_can_get_empty_list_of_server_seeds(self):
self.browser = webdriver.Firefox()
print('Before page open')
self.browser.get(self.live_server_url + '/')
print('After page open')
self.assertEqual(1, 1)
self.browser.quit()
}}}
Running it with 'python manage.py test functional_tests/' result with
success:
{{{
...
Before page open
After page open
.
----------------------------------------------------------------------
Ran 1 test in 7.048s
OK
...
}}}
But if I change LiveServerTestCase to StaticLiveServerTestCase then I am
getting strange error:
{{{
$ python manage.py test functional_tests/
Creating test database for alias 'default'...
