Django's LiveServerTestCase Always Fails Due to Conflicting Address… Despite Address Appearing Free

Question

I\'m currently working on cleaning my Django functional tests to use the LiveServerTestCase rather than bouncing selenium based tests off an instance of the development envi

Answer 1

If environment variable DJANGO_LIVE_TEST_SERVER_ADDRESS is not set the default address to start the live test server is localhost:8081. See LiveServerTestCase src code.

  # Launch the live server's thread
    specified_address = os.environ.get(
        'DJANGO_LIVE_TEST_SERVER_ADDRESS', 'localhost:8081')

As the OS seems to be complaining about the port 8081 being in use. One can quickly pick another port (say 9000) by running the tests like below.

/manage.py test functional_tests --liveserver :9000

However, explicitly setting the DJANGO_LIVE_TEST_SERVER_ADDRESS would be ideal.

export DJANGO_LIVE_TEST_SERVER_ADDRESS="localhost:9000"
