Subject: [PATCH]   Add isolated testing settings for awx testing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

  Introduces settings_for_isolated_testing.py to provide a self-contained
  test environment for awx testing.

  Key Features:
  - SQLite database configuration for faster, isolated test runs
  - ServiceID mocking infrastructure to prevent UUID validation errors
  - Resource server sync disabling to avoid authentication errors in tests
  - Memory-based caching for test isolation

  Testing Infrastructure Patterns:
  - Sample mock_dab_service_id() fixture for ServiceID.objects.first() calls
  - MOCK_DAB_SERVICE_ID setting to enable/disable mocking conditionally
  - RESOURCE_SERVER = {} configuration to disable external sync during testing
  - Comprehensive documentation for reuse in future DAB-related testing

  This testing foundation enables reliable unit and integration testing
  of django-ansible-base components without requiring external PostgreSQL
  databases or live service dependencies.

  Usage: pytest --ds=awx.main.tests.settings_for_isolated_testing

+AWX Settings for Isolated Testing
+
+This settings module provides a fully isolated testing environment that:
+- Uses SQLite instead of PostgreSQL for faster, isolated test runs
+- Disables DAB (django-ansible-base) resource sync to prevent 401 errors
+- Mocks DAB ServiceID dependencies to avoid database table requirements
+- Provides in-memory caching for test isolation
+
+Usage:
+    pytest --ds=awx.main.tests.settings_for_isolated_testing [test_file]
+
+Enhanced Usage Notes:
+1. ServiceID Mocking Pattern:
+   Sample fixture code pattern to add to test files to prevent: "AttributeError: 'NoneType' object has no attribute 'pk'"
+
+   # Mock the service_id field default for testing when DAB resource registry tries to access ServiceID.objects.first().pk
+   @pytest.fixture(autouse=True)
+   def mock_dab_service_id():
+       from django.conf import settings
+       import uuid
+
+       if getattr(settings, 'MOCK_DAB_SERVICE_ID', False):
+           with patch('ansible_base.resource_registry.models.service_identifier.ServiceID.objects.first') as mock_first:
+               mock_service = MagicMock()
+               mock_service.pk = uuid.uuid4()
+               mock_first.return_value = mock_service
+               yield
+       else:
+           yield
+
+   - MOCK_DAB_SERVICE_ID setting to enable/disable mocking
+
+2. DAB Resource Server Isolation:
+   - RESOURCE_SERVER = {} setting disables DAB sync during testing
+   - Prevents 401 authentication errors in test environments
+
+3. SQLite Testing Configuration:
+   - Fast, isolated test database setup
+   - No PostgreSQL permissions or setup required
