Rule: E2E Test Fixture Data Management

Core Principle

Think of e2e_seed.json like a test-suite-level setUp() method. All test data lives in fixtures. No ORM operations during test execution.

Adding Test Data to e2e_seed.json

1. Review Current Data

# Check what data already exists
cat tests/fixtures/e2e_seed.json | jq '.[].model' | sort | uniq -c

2. Add Authentication Token to Fixtures

// Add to tests/fixtures/e2e_seed.json
[
  // ... existing data ...
  {
    "model": "authtoken.token",
    "pk": 1,
    "fields": {
      "user": 1,
      "created": "2023-01-01T00:00:00.000Z",
      "key": "abcdef1234567890abcdef1234567890abcdef12"
    }
  }
]

3. Option A: Generate from Database

# Create the data you need in Django admin or shell
python manage.py shell
>>> from api.models import Intent
>>> Intent.objects.create(user_id=1, name="Test Intent", startag="TEST", motive="Testing")

# Export to fixture format
python manage.py dumpdata api.Intent --indent 2 >> new_data.json

# Merge into e2e_seed.json (manually or with jq)

4. Option B: Write JSON Directly

// Add to tests/fixtures/e2e_seed.json
[
  // ... existing data ...
  {
    "model": "api.intent",
    "pk": 99,
    "fields": {
      "user": 1,
      "name": "Test Scenario Intent",
      "startag": "TESTSCENARIO",
      "motive": "For testing specific scenario",
      "color": "#ff6b6b",
      "priority": 99,
      "active": true
    }
  }
]

5. Reference Known Data in Tests

# In your test, reference the pre-seeded data
def test_scenario(self, authenticated_page, base_url):
    app_url = base_url or "http://localhost:5173"
    intents_page = IntentsPage(authenticated_page, app_url)
    intents_page.goto()
    
    # Use known data from e2e_seed.json
    # User: denis.petelin (pk=1)
    # Intent: WORK (pk=1), TESTSCENARIO (pk=99)
    # Token: abcdef1234567890abcdef1234567890abcdef12
    
    # Verify authentication worked
    expect(authenticated_page.get_by_text("Add Intent")).to_be_visible()
