Payment Test Gen

Mock-Patterns

Stripe

from unittest.mock import patch, MagicMock

@patch("app.services.stripe_service.stripe.Webhook.construct_event")
def test_stripe_webhook_payment_succeeded(mock_construct):
    mock_construct.return_value = {
        "type": "payment_intent.succeeded",
        "data": {"object": {"id": "pi_test_123", "amount": 5000}}
    }
    # ...

PayPal

@patch("app.services.paypal_service.requests.post")
def test_paypal_ipn_verified(mock_post):
    mock_post.return_value = MagicMock(text="VERIFIED", status_code=200)
    # ...

SEPA

def test_sepa_xml_generation():
    """SEPA-XML (pain.008) muss Schema-valide sein."""
    # ...

Test-Template

Jeder generierte Test folgt diesem Muster:

"""Tests for {service_name} — {beschreibung}."""

import pytest
from unittest.mock import patch, MagicMock
from fastapi.testclient import TestClient

from app.main import app

client = TestClient(app)


class TestStripeWebhook:
    """Stripe Webhook Handler Tests."""

    def test_valid_payment_succeeded(self):
        """Successful payment triggers CRM update and receipt."""
        ...

    def test_invalid_signature_rejected(self):
        """Invalid webhook signature returns 400."""
        ...

    def test_duplicate_event_idempotent(self):
        """Duplicate event IDs are handled idempotently."""
        ...

Sicherheit

• KEINE echten API-Keys in Tests — nur sk_test_*, pk_test_*
• KEINE echten IBANs — Test-IBANs verwenden (DE89370400440532013000)
• KEINE echten Webhook-Secrets — Mock-Secrets wie whsec_test_123
