Frappe Integration Test Generator

Generate comprehensive integration tests for multi-DocType workflows and end-to-end business processes in Frappe.

Global Rules

These Frappe conventions apply to everything this skill generates, and override any conflicting example below.

• Bench commands: use bare bench (never ./env/bin/bench or a full path). Always pass --site <site> explicitly — never run a bare bench migrate / bench run-tests. Run bench start in the background and only if it isn't already running. Don't run discovery commands (which bench, bench --version).
• DocType files live at apps/<app>/<app>/<module>/doctype/<name>/<name>.json — the app name appears twice (directory + Python package) — with an empty __init__.py alongside. Never mkdir the folder; write the JSON and run bench --site <site> migrate to create the structure. Don't add creation, modified, owner, modified_by, or docstatus as fields — Frappe manages them.
• Database & ORM: prefer frappe.qb.get_query() over raw frappe.db.sql(). Use frappe.db.get_all() for server logic (ignores permissions) and frappe.db.get_list() for user-facing APIs (enforces them). Never use frappe.db.set_value() on a field with validation or lifecycle logic — load the doc and doc.save() so controller hooks run. Batch-fetch related records; never query inside a loop (N+1).
• Never call frappe.db.commit() in controllers, request handlers, background jobs, or patches — Frappe auto-commits on success and rolls back on uncaught errors. Flush manually only to make a write visible to a subsequent frappe.enqueue() (or pass enqueue_after_commit=True).
• Permissions & APIs: put permission checks inside controller methods (enforced on every call path), not in API wrappers. Type-hint every @frappe.whitelist() parameter so Frappe validates and casts it, and pass methods=[...] to pin the HTTP verb.

When to Use This Skill

Claude should invoke this skill when:

• User wants to test complete workflows
• User needs end-to-end scenario testing
• User mentions integration tests or workflow testing
• User wants to test multi-DocType interactions
• User needs to verify business process integrity

Test Site

Run tests on a separate site from the dev site — integration tests create, modify, and delete data across many DocTypes. If the dev site is app.localhost, create app-test.localhost, install the app there, and run tests against it:

bench new-site app-test.localhost --admin-password admin
bench --site app-test.localhost install-app <app>
bench --site app-test.localhost run-tests --app <app>

Always pass --site — never run a bare bench run-tests. If a test fails with "DocType not found", run bench --site app-test.localhost migrate first.

Conventions

• Inherit from frappe.tests.IntegrationTestCase (multi-DocType workflows always touch the DB).
• Each test runs inside a transaction that auto-rolls-back — do not write manual teardown/cleanup or call frappe.db.rollback().
• For permission-context tests, switch the active user with frappe.set_user("user@example.com") and restore it (e.g. frappe.set_user("Administrator")) at the end of the test.
• Mock or avoid real external API calls in tests — use unittest.mock.patch so tests stay deterministic and offline.
• Feature-wise tests spanning multiple DocTypes live at apps/<app>/<app>/tests/test_<feature>.py; a workflow test centred on one DocType can live alongside it at apps/<app>/<app>/<module>/doctype/<doctype>/test_<doctype>.py.

Capabilities

1. Workflow Integration Test

Complete Sales Workflow Test:

import frappe
from frappe.tests import IntegrationTestCase

class TestSalesWorkflow(IntegrationTestCase):
    def test_complete_sales_cycle(self):
        """Test end-to-end sales process"""
        # 1. Create Customer
        customer = self._create_test_customer()

        # 2. Create Sales Order
        so = self._create_sales_order(customer.name)
        so.submit()

        # 3. Create Sales Invoice from SO
        si = self._make_sales_invoice_from_order(so.name)
        si.insert()
        si.submit()

        # 4. Create Payment Entry
        pe = self._create_payment_entry(si)
        pe.insert()
        pe.submit()

        # Verify workflow completed
        si.reload()
        self.assertEqual(si.status, 'Paid')
        self.assertEqual(si.outstanding_amount, 0)

    def _create_test_customer(self):
        return frappe.get_doc({
            'doctype': 'Customer',
            'customer_name': '_Test Customer',
            'customer_group': 'Commercial'
        }).insert()

    def _create_sales_order(self, customer):
        return frappe.get_doc({
            'doctype': 'Sales Order',
            'customer': customer,
            'delivery_date': frappe.utils.add_days(frappe.utils.today(), 7),
            'items': [{
                'item_code': '_Test Item',
                'qty': 10,
                'rate': 100
            }]
        })

2. State Transition Test

Test Document States:

class TestInvoiceStates(IntegrationTestCase):
    def test_invoice_state_transitions(self):
        """Test all possible state transitions"""
        si = self._get_test_invoice()

        # Draft state
        si.insert()
        self.assertEqual(si.docstatus, 0)
        self.assertEqual(si.status, 'Draft')

        # Submit transition
        si.submit()
        self.assertEqual(si.docstatus, 1)
        self.assertEqual(si.status, 'Submitted')

        # Cannot edit submitted
        si.customer = 'Different Customer'
        with self.assertRaises(frappe.ValidationError):
            si.save()

        # Cancel transition
        si.cancel()
        self.assertEqual(si.docstatus, 2)
        self.assertEqual(si.status, 'Cancelled')

3. Permission-Context Test

Switch the active user to assert a workflow behaves correctly per role, then restore the user. The auto-rollback transaction cleans up any documents created.

class TestApprovalPermissions(IntegrationTestCase):
    def test_only_manager_can_approve(self):
        """A regular user cannot approve; a manager can"""
        expense = self._create_test_expense()

        # Regular user is denied
        frappe.set_user("user@example.com")
        with self.assertRaises(frappe.PermissionError):
            expense.approve()

        # Manager succeeds
        frappe.set_user("manager@example.com")
        expense.reload()
        expense.approve()
        self.assertEqual(expense.status, "Approved")

        # Restore the default test user
        frappe.set_user("Administrator")

4. Mocking External Calls

Never hit a real external service from a test. Patch the call so the test stays deterministic and offline.

from unittest.mock import patch

class TestPaymentSync(IntegrationTestCase):
    @patch("my_app.gateway.charge_card")
    def test_payment_marks_invoice_paid(self, mock_charge):
        mock_charge.return_value = {"status": "succeeded"}
        si = self._create_test_invoice()
        si.collect_payment()
        self.assertEqual(si.status, "Paid")
        mock_charge.assert_called_once()
