Different db for testing in Django?

Question

DATABASES = {
#    \'default\': {
#        \'ENGINE\': \'postgresql_psycopg2\',
#        ...
#    }

    # for unit tests
    \'default\': {
        \'ENGINE\': \'dj         


        

Answer 1

You can specify test database in settings.py. See https://docs.djangoproject.com/en/3.0/topics/testing/overview/#the-test-database

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'USER': 'mydatabaseuser',
        'NAME': 'mydatabase',
        'TEST': {
            'NAME': 'mytestdatabase',
        },
    },
}

Answer 2

This accelerated dramatically test execution.

import sys

if 'test' in sys.argv:
    DATABASES['default'] = {
        'ENGINE': 'django.db.backends.sqlite3',
        'TEST_CHARSET': 'UTF8', # if your normal db is utf8
        'NAME': ':memory:', # in memory
        'TEST_NAME': ':memory:', # in memory
    }

    DEBUG = False # might accelerate a bit
    TEMPLATE_DEBUG = False

    from django.core.management import call_command
    call_command('syncdb', migrate=True) # tables don't get created automatically for me
