Hi!
It boils down to this:
I have a selenium test in a django project against the admin page. All green.
If I duplicate the test class via copy and paste + renaming, then one is green and one is red, despite containing the same code. I expected
both to be green.
I have removed the tests from the project just to make sure that there is no inteference. The following steps should allow anyone to reproduce
the behavior in a new project/app.
For the record: Python 3.4.1 Django 1.8.5 Selenium 2.48.0
django-admin startproject temp
cd temp
manage startapp blog
adjust settings.py to include 'blog' in INSTALLED_APPS
add a single class to models.py
class Post(models.Model):
text = models.TextField()
register the model with admin site in admin.py add:
from blog.models import Post
admin.site.register(Post)
manage makemigrations
manage migrate
manage createsuperuser
admin
admin@localhost
admin
manage runserver
Check that you can login via the admin page and add posts.
Now add the following test to tests.py:
from django.contrib.auth.models import User
from django.contrib.staticfiles.testing import StaticLiveServerTestCase
from blog.models import Post
from selenium import webdriver
class AdminTest(StaticLiveServerTestCase):
def login_to_django_admin(self):
self.credentials = {
'username': 'admin',
'email': 'admin@localhost',
'password': 'admin'
}
User.objects.create_superuser(**self.credentials)
# go to the admin site
self.browser.get(self.live_server_url + '/admin/')
# we are not logged in, it redirects us to the login page
self.assertEquals(self.browser.current_url, self.live_server_url +
'/admin/login/?next=/admin/')
# login in
inputbox = self.browser.find_element_by_id('id_username')
inputbox.send_keys('admin')
inputbox = self.browser.find_element_by_id('id_password')
inputbox.send_keys('admin')
submit = 'input[type="submit"]'
submit = self.browser.find_element_by_css_selector(submit)
submit.click()
self.browser.find_element_by_class_name('app-blog')
def test_insert_Post_via_django_admin(self):
self.browser = webdriver.Firefox()
self.login_to_django_admin()
# now that we are logged in, look at the Post model add page to get a
csrftoken
self.browser.get(self.live_server_url + '/admin/blog/post/add/')
inputbox = self.browser.find_element_by_id('id_text')
inputbox.send_keys('barfoo')
submit = 'input[type="submit"][name="_save"]'
submit = self.browser.find_element_by_css_selector(submit)
submit.click()
# we should see it on the other side via python db access
saved_beiträge = Post.objects.all()
self.assertEquals(saved_beiträge.count(), 1)
self.assertEquals(saved_beiträge[0].text, 'barfoo')
# try to look at it
self.browser.get(self.live_server_url + '/admin/blog/post/1/')
# modify it
inputbox = self.browser.find_element_by_id('id_text')
inputbox.send_keys('text')
submit = 'input[type="submit"][name="_save"]'
submit = self.browser.find_element_by_css_selector(submit)
submit.click()
# we should see the change at the other end
saved_posts = Post.objects.all()
self.assertEquals(saved_posts.count(), 1)
self.assertEquals(saved_posts[0].text, 'barfootext')
Now run it via:
manage test
Selenium opens Firefox and walks through the admin page as it should. Test
green.
Now duplicate the whole class and rename it and run the tests again.
manage test
One is green the other is not. In fact Selenium opens a second Firefox instance
as it should. But this time
self.browser.get(self.live_server_url + '/admin/blog/post/1/')
results in a 404 not found.
Now delete the whole class that is passing and run the test again.
manage test
Now the failing one is green as well.
I can't wrap my head around this. What am I missing?
Is it a Django issue or a Selenium issue?
Is it a known problem?
Thanks
Uli
