Odoo Test Helper

odoo-test-helper is toolbox for writing odoo test

Loading Fake models

Sometime you build an abstract module that can be use by many modules. In such case, if you want to test it with real records you need to register real models.

One solution is to create a module_test module with a little implementation that use your abstract model.

One other solution is define test only models and load them in tests. This lib makes this possible and easy.

Example

There is an example of test here:

• test_example.py.

This example load the class ResPartner from the file:

• models.py.

Real implementation case can be found in the following module

• connector_search_engine.

• base_url.

How to import

Be carefull importing fake class must be done in the right way. Importing a file will automatically add all the class in the “module_to_models” variable. The import must be done after the backup !

Wrong way

from odoo.tests import SavepointCase

from odoo_test_helper import FakeModelLoader

# The fake class is imported here !! It's wrong
# And be carefull even if you only import ResPartner
# all class in the file models will be proceded by odoo
# so no **direct import** of a file that contain fake model
from .models import ResPartner





class TestMixin(SavepointCase):
    @classmethod
    def setUpClass(cls):
        super(TestMixin, cls).setUpClass()
        cls.loader = FakeModelLoader(cls.env, cls.__module__)
        cls.loader.backup_registry()

        cls.loader.update_registry((ResPartner,))

    @classmethod
    def tearDownClass(cls):
        cls.loader.restore_registry()
        super(TestMixin, cls).tearDownClass()

    def test_create(self):
        partner = self.env["res.partner"].create({"name": "BAR", "test_char": "youhou"})
        self.assertEqual(partner.name, "FOO-BAR")
        self.assertEqual(partner.test_char, "youhou")

Right Way

from odoo.tests import SavepointCase

from odoo_test_helper import FakeModelLoader


class TestMixin(SavepointCase):
    @classmethod
    def setUpClass(cls):
        super(TestMixin, cls).setUpClass()
        cls.loader = FakeModelLoader(cls.env, cls.__module__)
        cls.loader.backup_registry()

        # The fake class is imported here !! After the backup_registry
        from .models import ResPartner

        cls.loader.update_registry((ResPartner,))

    @classmethod
    def tearDownClass(cls):
        cls.loader.restore_registry()
        super(TestMixin, cls).tearDownClass()

    def test_create(self):
        partner = self.env["res.partner"].create({"name": "BAR", "test_char": "youhou"})
        self.assertEqual(partner.name, "FOO-BAR")
        self.assertEqual(partner.test_char, "youhou")

History

This module is inspired of the following mixin code that can be found in OCA and shopinvader repository

• Mixin in OCA: https://github.com/OCA/search-engine/blob/7fd85a74180cfff30e212fca01ebeba6c54ee294/connector_search_engine/tests/models_mixin.py

• Mixin in Shopinvader: https://github.com/shopinvader/odoo-shopinvader/blob/b81b921ea52c911e5b33afac88adb8f9a1c02626/base_url/tests/models_mixin.py

• Simone Orsi <[e-mail]>

Refactor/extraction have been done by

• Sébastien BEAU <[e-mail]>

This refactor try to load all class correctly like Odoo does with the exact same syntax

Note this refactor/extraction have been done to fix the test of the following issue

https://github.com/shopinvader/odoo-shopinvader/pull/607

Changes

2.0.3

• [FIX] restore_registry in Odoo 16

  See odoo/odoo@cd12293

  This new attribute is the source of truth for the base classes and in setup_models (called further down in the modified code in this PR), the model’s base classes are reset from it:
