How do I run redis on Travis CI? - django

Question

I am practicing unit testing using django
In items/tests.py
class NewBookSaleTest(SetUpLogInMixin):
def test_client_post_books(self):
send_post_data_post = self.client.post(
'/booksale/',
data = {
'title':'Book_A',
}
)
new_post = ItemPost.objects.first()
self.assertEqual(new_post.title, 'Book_A')
In views/booksale.py
class BookSale(LoginRequiredMixin, View):
login_url = '/login/'
def get(self, request):
[...]
def post(self, request):
title = request.POST.get('title')
saler = request.user
created_bookpost = ItemPost.objects.create(
user=saler,
title=title,
)
# redis + celery task queue
auto_indexing = UpdateIndexTask()
auto_indexing.delay()
return redirect(
[...]
)
when I run unit test, raise redis connection error
redis.exceptions.ConnectionError
I know when I running redis-server and celery is error will solve
but when I run unit test in Travis CI I can't run redis-server and celery in Travis CI
So, I found this link
I try insert this code in .travis.yml
language:
python
python:
- 3.5.1
addons:
postgresql:"9.5.1"
install:
- pip install -r requirement/development.txt
service:
- redis-server
# # command to run tests
script:
- pep8
- python wef/manage.py makemigrations users items
- python wef/manage.py migrate
- python wef/manage.py collectstatic --settings=wef.settings.development --noinput
- python wef/manage.py test users items --settings=wef.settings.development
but it shows same error
so I found next link
before_script:
- sudo redis-server /etc/redis/redis.conf --port 6379 --requirepass 'secret'
but... it show same error...
how can I running redis-server in travis ci?

If you have not solve the problem now, here is a solution.
Remove the service line.
Redis is provided by the test environment as a default component, so
service:
- redis-server
will be translated as:
service redis start
In this problem, we want to customize redis to add password auth. So we doesn't need travis ci to start redis service. Just use the before_script.
And after all, your .travis.yml should be this:
language:
python
python:
- 3.5.1
addons:
postgresql:"9.5.1"
install:
- pip install -r requirement/development.txt
before_script:
- sudo redis-server /etc/redis/redis.conf --port 6379 --requirepass 'secret'
# # command to run tests
script:
- pep8
- python wef/manage.py makemigrations users items
- python wef/manage.py migrate
- python wef/manage.py collectstatic --settings=wef.settings.development --noinput
- python wef/manage.py test users items --settings=wef.settings.development
