Setting liveserver port when running tests in django

Question

I am using django for a webapp and I'm using docker to deploy it. I need to test it in the container with selenium. I'm using selenium grid for testing. In order to connect with the liveserver on the docker, i need to port forward a specific port, but as far as i read in the django docs, LiveServerTestCase uses port 0, which means random port every time i run the tests. Since --liveserver options is deprecated, is there any other way to set the port of the test server or a smarter way to test it with selenium ?

Thanks in advance !

Answer 1

If anyone is wondering this is how I did it: Override method setUpClass, which starts the thread on which the server run

@classmethod
def setUpClass(cls):
    cls.host = "example.com" # or ip
    cls.port = 12345
    super(ExampleTestCase, cls).setUpClass()

You method works (thanks!), but your code is misleading: You're writing a class method, so you get the class (and not an instance of that class) which is called cls by convention. – Adela

Not bad idea to say that after the first comment, the author has edited the answer using the comment proposition. – Liverwort

Answer 2

All the previous answers work well, but the most succinct way to set the port is as follows:

class MyTestCase(LiveServerTestCase):
    port = 12345

According to the Django 1.11 release notes you should set the port attribute on the LiveServerTestCase:

If you need to bind LiveServerTestCase to a specific port, use the port attribute added in Django 1.11.2.
