Frappe Integration Test Generator Skill

Frappe Integration Test Generator

Build robust integration tests that validate the interaction between multiple DocTypes, Background Jobs, and external Microservices.

Test Data Builder Pattern

Avoid messy setUp methods by using dedicated builder functions or the "Object Mother" pattern to create consistent test data.

class TestDataBuilder:
    @staticmethod
    def create_customer(name="_Test Customer"):
        if not frappe.db.exists("Customer", name):
            return frappe.get_doc({
                "doctype": "Customer",
                "customer_name": name,
                "customer_group": "All Customer Groups",
                "territory": "All Territories"
            }).insert(ignore_permissions=True)
        return frappe.get_doc("Customer", name)

    @staticmethod
    def create_item(item_code="_Test Item"):
        # ... logic to create item with default warehouse ...

Distributed Service & Health Checks

When testing integrations with external services (e.g., a Go-based Cloud Agent), verify the "Distributed Health" of the system.

class TestMicroserviceIntegration(FrappeTestCase):
    def test_service_health(self):
        """Verify the external service is reachable before running tests"""
        from frappe.utils.commands import run_command
        # Example: check if a sidecar service is responsive
        response = frappe.make_get_request("http://cloud-agent:8080/health")
        self.assertEqual(response.get("status"), "UP")

    def test_distributed_transaction(self):
        """Test if a DocType change propagates to the external service"""
        doc = frappe.get_doc({"doctype": "K8s Cluster", "cluster_name": "Test"}).insert()
        # Wait for background job or async event
        frappe.db.commit() 
        # Verify side-effect in external system
        self.assertTrue(self._check_external_state("Test"))

Workflow State Validation

Ensure state transitions are atomic and consistent across the testing pyramid.

| Step | Action | Expected State | |---|---|---| | 1 | Create Draft | docstatus == 0 | | 2 | Trigger Workflow | status == "Pending Approval" | | 3 | Submit | docstatus == 1 and Linked Docs Created |

Best Practices

Idempotency: Tests should be runnable multiple times on the same site without conflict (use frappe.db.rollback() or unique naming).
Background Jobs: Use frappe.enqueue with now=frappe.flags.in_test to test async logic synchronously.
Sidecar Validation: If your app depends on Redis or Socket.io, include a "Sanity Test" in your suite.
