Issue Summary

Hi there, I’m new here and I’m trying to run the docker-compose tests described here https://redash.io/help/open-source/dev-guide/docker
But many of the tests were failing because it couldn’t connect to the database

Technical details:

To run the tests I did the following steps:

  1. Ran docker-compose up
  2. docker-compose run --rm postgres psql -h postgres -U postgres -c "create database tests"
  3. docker-compose run --rm server tests

Here I put one unit test output, which is the same as all other:

self = <tests.test_authentication.TestApiKeyAuthentication testMethod=test_disabled_user_api_key>

    def setUp(self):
        super(TestApiKeyAuthentication, self).setUp()
        self.api_key = "10"
>       self.query = self.factory.create_query(api_key=self.api_key)

        Create a new database connection.
    
        The connection parameters can be specified as a string:
    
            conn = psycopg2.connect("dbname=test user=postgres password=secret")
    
        or using a set of keyword arguments:
    
            conn = psycopg2.connect(database="test", user="postgres", password="secret")
    
        Or as a mix of both. The basic connection parameters are:
    
        - *dbname*: the database name
        - *database*: the database name (only as keyword argument)
        - *user*: user name used to authenticate
        - *password*: password used to authenticate
        - *host*: database host address (defaults to UNIX socket if not provided)
        - *port*: connection port number (defaults to 5432 if not provided)
    
        Using the *connection_factory* parameter a different class or connections
        factory can be specified. It should be a callable object taking a dsn
        argument.
    
        Using the *cursor_factory* parameter, a new default cursor factory will be
        used by cursor().
    
        Using *async*=True an asynchronous connection will be created. *async_* is
        a valid alias (for Python versions where ``async`` is a keyword).
    
        Any other keyword parameter will be passed to the underlying client
        library: the list of supported parameters depends on the library version.
