Odoo Testing Core

Odoo Testing Core

Goal

Create automated tests that run with odoo-bin -i my_module --test-enable.

1. Test Structure

Tests are located in the tests/ directory.

my_module/
├── tests/
│   ├── __init__.py
│   └── test_estate.py

You MUST import tests in your module's __init__.py.

2. Unit Testing (TransactionCase)

The most common test class. It runs each test method in a separate transaction that is rolled back at the end. The database state is preserved between tests.

from odoo.tests.common import TransactionCase, tagged
from odoo.exceptions import UserError

@tagged('post_install', '-at_install')
class TestEstateProperty(TransactionCase):

    def setUp(self):
        super(TestEstateProperty, self).setUp()
        self.property = self.env['estate.property'].create({
            'name': 'Test Property',
            'expected_price': 100000,
        })

    def test_property_creation(self):
        """Test that the property is created with correct defaults"""
        self.assertEqual(self.property.state, 'new')

    def test_selling_price_constraint(self):
        """Test that low selling price raises an error"""
        with self.assertRaises(UserError):
            self.property.selling_price = 50000 # Too low

3. The tagged Decorator

Controls when tests run.

• standard: Runs by default.
• at_install: Runs immediately after module installation (default).
• post_install: Runs after all modules are installed (Recommended).
• nice_to_have: Specific tag to filter tests (odoo-bin --test-tags .nice_to_have).

To run tests:

odoo-bin -c odoo.conf -i estate --test-enable --stop-after-init
# Or specific tags
odoo-bin -c odoo.conf --test-tags /estate

4. UI Testing within Python (Form)

Simulates a user opening a Form view, editing fields, and saving. This triggers onchange and compute methods automatically.

from odoo.tests import Form

def test_onchange_garden(self):
    # Edit existing record
    with Form(self.property) as f:
        f.garden = True
        # verify onchange effect
        self.assertEqual(f.garden_area, 10)
        self.assertEqual(f.garden_orientation, 'north')
        
    # Create new record
    with Form(self.env['estate.property']) as f:
        f.name = "New House"
        f.expected_price = 100000
    new_prop = f.save()

5. Integration/Tour Tours (HttpCase)

Used for testing the Javascript UI (Tours). (See odoo_testing_tours skill - to be created if needed).
