Testing

Frappe provides some basic tooling to write automated tests. There are some basic rules:

  1. Test can be anywhere in your repository but must begin with test_ and should be a .py file.
  2. The test runner will automatically build test records for dependent DocTypes identified by the Link type field (Foreign Key).
  3. For non-DocType tests, you can write simple unit tests and prefix your file names with test_.

Writing Tests

When you create a new DocType (in developer mode), the boilerplate files also contain the test_{doctype}.py file. The test file should handle creating dependencies and cleaning them up.

Here is a sample test file referred from test_event.py.

import frappe
import unittest

def create_events():
    if frappe.flags.test_events_created:
        return

    frappe.set_user("Administrator")
    doc = frappe.get_doc({
        "doctype": "Event",
        "subject":"_Test Event 1",
        "starts_on": "2014-01-01",
        "event_type": "Public"
    }).insert()

    doc = frappe.get_doc({
        "doctype": "Event",
        "subject":"_Test Event 3",
        "starts_on": "2014-01-01",
        "event_type": "Public"
        "event_individuals": [{
            "person": "test1@example.com"
        }]
    }).insert()

    frappe.flags.test_events_created = True


class TestEvent(unittest.TestCase):
    def setUp(self):
        create_events()

    def tearDown(self):
        frappe.set_user("Administrator")

    def test_allowed_public(self):
        frappe.set_user("test1@example.com")
        doc = frappe.get_doc("Event", frappe.db.get_value("Event",
            {"subject":"_Test Event 1"}))
        self.assertTrue(frappe.has_permission("Event", doc=doc))

    def test_not_allowed_private(self):
        frappe.set_user("test1@example.com")
        doc = frappe.get_doc("Event", frappe.db.get_value("Event",
            {"subject":"_Test Event 2"}))
        self.assertFalse(frappe.has_permission("Event", doc=doc))

Running Tests

Run the following command to run all your tests. It will build all the test dependencies once and run your tests. You should run tests from frappe_bench folder.

# run all tests
bench --site [sitename] run-tests

# run tests for only frappe app
bench --site [sitename] run-tests --app frappe

# run tests for the Task doctype
bench --site [sitename] run-tests --doctype "Task"

# run a test using module path
bench --site [sitename] run-tests --module frappe.tests.test_api

# run a specific test from a test file
bench --site [sitename] run-tests --module frappe.tests.test_api --test test_insert_many

# run tests without creating test records
bench --site [sitename] run-tests --skip-test-records --doctype "Task"

# profile tests and show a report after tests execute
bench --site [sitename] run-tests --profile --doctype "Task"
.
