Middleware Integration Tests

Overview

These tests verify that the middleware stack (StoreContextMiddleware, ThemeContextMiddleware, ContextMiddleware) works correctly through real HTTP requests.

Architecture

Pre-registered Test Routes

All test routes are defined in middleware_test_routes.py and registered at module load time. This avoids conflicts with catch-all routes in main.py.

Routes are organized by prefix:

• /middleware-test/* - General middleware testing
• /api/middleware-test/* - API context testing
• /admin/middleware-test/* - Admin context testing
• /shop/middleware-test/* - Shop context testing

Test Fixtures (conftest.py)

The client fixture patches middleware dependencies for proper test isolation:

@pytest.fixture
def client(db):
    with patch("middleware.store_context.get_db", override_get_db):
        with patch("middleware.theme_context.get_db", override_get_db):
            with patch("middleware.store_context.settings") as mock_settings:
                mock_settings.main_domain = "platform.com"
                client = TestClient(app)
                yield client

This ensures:

1. Database isolation: Middleware uses the test database session
2. Subdomain detection: platform.com is used so hosts like teststore.platform.com work correctly

Store Dashboard Context Testing

Store dashboard context detection (/store/* paths → STORE_DASHBOARD context) is tested via unit tests rather than integration tests because:

1. The /store/{store_code}/{slug} catch-all route in main.py intercepts /store/middleware-test/* paths
2. Unit tests in tests/unit/middleware/test_context.py provide comprehensive coverage:
   • test_detect_store_dashboard_context
   • test_detect_store_dashboard_context_direct_path
   • test_store_dashboard_priority_over_shop
   • test_middleware_sets_store_dashboard_context

Testing Patterns

Subdomain Detection

Use hosts ending in .platform.com:

response = client.get(
    "/middleware-test/subdomain-detection",
    headers={"host": "mystore.platform.com"}
)

Custom Domain Detection

Custom domains require is_verified=True in the StoreDomain fixture:

domain = StoreDomain(
    store_id=store.id,
    domain="customdomain.com",
    is_active=True,
    is_primary=True,
    is_verified=True  # Required for detection
)

Context Type Verification

Routes return context information for assertions:

response = client.get("/api/middleware-test/context")
data = response.json()
assert data["context_type"] == "api"
assert data["context_enum"] == "API"

Theme Structure

Theme data uses nested structure:

• theme["colors"]["primary"] - Primary color
• theme["branding"]["logo"] - Logo URL
• theme["custom_css"] - Custom CSS

Test routes flatten this for easier assertions:

data = response.json()
assert data["primary_color"] == "#FF5733"  # Flattened from colors.primary
