odoo-testing-framework

Use this skill whenever the user is writing, reviewing, debugging, or planning tests for an Odoo Community module. Trigger phrases: "write a test", "add a unit test", "pytest-odoo", "TransactionCase", "BDD scenario", "Gherkin", "fixture", "conftest", "test is failing", "coverage", "factory", "assertQueryCount", "pre-commit", "CI pipeline", "template database", "Runboat", "Playwright", "E2E test", "CLAUDE.md", "GitLab CI", "ArgoCD", "how do I test", "vibe code Odoo". Also trigger when the user opens or edits any file matching tests/test_*.py, features/*.feature, conftest.py, or .gitlab-ci.yml in an Odoo repo.

Odoo Testing Framework Skill

This skill encodes the complete ITSulu testing framework for Odoo Community modules. Read it top to bottom the first time you consult it in a session; return to specific sections as needed during development.

---

0. The Golden Rules (read these first every time)

1. Test first. Write a failing test before any implementation code. Never write implementation and tests at the same time.
2. One behaviour per test. Each test method verifies exactly one assertion. The method name is the specification: test_gold_tier_gets_ten_percent_discount.
3. Isolate with TransactionCase. Unit tests roll back automatically. Never clean up the database manually.
4. Template databases, always. Every CI job that runs tests must use a primed template DB. Never install Odoo from scratch per test class.
5. 10–30 E2E scenarios, maximum. Playwright is for critical user journeys only.
6. BDD only when stakeholders read Gherkin. If they don't, use TDD with descriptive names. Do not generate Gherkin no-one will read.
7. Mask all CI secrets. Never commit tokens, passwords, or keys to YAML.
8. Every addition is pain-driven. Add a tool only when a concrete problem demands it, not because the roadmap has a box for it.

2. TDD Cycle

RED   → write test describing one behaviour (must fail)
GREEN → write minimum code to make it pass
REFACTOR → clean up; test stays green
REPEAT → next behaviour

Cycle time target: 5–15 minutes per behaviour.

Never skip RED. Never write code before the test exists.

---

3. Writing pytest-odoo Tests

3.1 TransactionCase (default — use for almost everything)

from odoo.tests import TransactionCase, tagged

@tagged('post_install', '-at_install', 'sale')
class TestSaleOrderDiscount(TransactionCase):
    """Loyalty discount rules on sale order lines."""

    @classmethod
    def setUpClass(cls):
        super().setUpClass()
        # Expensive shared setup — runs once per class
        cls.product = cls.env['product.product'].create({
            'name': 'Widget', 'list_price': 100.0, 'type': 'consu'
        })

    def _make_order(self, tier):
        """Helper — always use helpers for repeated data creation."""
        partner = self.env['res.partner'].create({
            'name': f'Customer-{tier}', 'loyalty_tier': tier
        })
        return self.env['sale.order'].create({
            'partner_id': partner.id,
            'order_line': [(0, 0, {
                'product_id': self.product.id,
                'product_uom_qty': 1.0,
            })]
        })

    def test_gold_tier_gets_ten_percent_discount(self):
        order = self._make_order('gold')
        self.assertEqual(order.order_line.discount, 10.0)

    def test_silver_tier_gets_five_percent_discount(self):
        order = self._make_order('silver')
        self.assertEqual(order.order_line.discount, 5.0)

    def test_no_tier_gets_no_discount(self):
        order = self._make_order(False)
        self.assertEqual(order.order_line.discount, 0.0)

Rules:

• Class name: TestXxxYyy — describes the unit under test.
• Method name: complete sentence — test_what_when_condition.
• setUpClass: shared, expensive objects (products, categories, pricelists).
• setUp / inline: test-specific data (partners, orders, invoices).
• Do not create shared mutable state; each test must be independent.

Critical: Never call self.env.cr.commit() in code being tested by TransactionCase

• TransactionCase uses database savepoints; each test gets rolled back automatically
• commit() breaks the savepoint chain, causing InFailedSqlTransaction errors in subsequent tests
• Use self.env.flush_all() instead to persist changes while keeping the test isolated
• If you need to test explicit commits, use TestCase instead (slower, no auto-rollback)

3.2 HttpCase (use rarely — only for controllers or UI tours)

from odoo.tests import HttpCase

class TestSaleOrderUI(HttpCase):
    def test_create_order_tour(self):
        self.start_tour('/odoo/sales', 'sale_order_tour', login='admin')

Use HttpCase only when the test genuinely requires a running controller or JavaScript tour. It is ~10× slower than TransactionCase.

3.3 Test tags

@tagged('post_install', '-at_install')   # Standard for module tests
@tagged('post_install', '-at_install', 'sale')   # + module-specific tag
@tagged('post_install', '-at_install', 'performance')  # Performance tests

Run subsets:

pytest addons/ -m sale           # Only sale-tagged tests
pytest addons/ -m "not slow"     # Exclude slow tests

3.4 Common assertions

self.assertEqual(record.field, expected)
self.assertIn(item, collection)
self.assertTrue(condition)
self.assertFalse(condition)
self.assertRaises(ValidationError, lambda: record.write({'field': bad_value}))

# Performance assertion — always add to hot paths
with self.assertQueryCount(50):
    records.action_confirm()

---

4. Test Data Factories

Use factories, not demo data. Demo data changes; factories are explicit contracts.

# addons/<module>/tests/factories.py

class OdooFactory:
    def __init__(self, env):
        self.env = env
        self._seq = 0

    def _next(self):
        self._seq += 1
        return self._seq

    def partner(self, **kw):
        vals = {'name': f'Partner-{self._next()}', 'email': f'p{self._next()}@test.com'}
        vals.update(kw)
        return self.env['res.partner'].create(vals)

    def product(self, **kw):
        vals = {'name': f'Product-{self._next()}', 'list_price': 100.0, 'type': 'consu'}
        vals.update(kw)
        return self.env['product.product'].create(vals)

    def sale_order(self, partner=None, lines=None, **kw):
        partner = partner or self.partner()
        lines = lines or [{'product_id': self.product().id, 'product_uom_qty': 1}]
        vals = {
            'partner_id': partner.id,
            'order_line': [(0, 0, l) for l in lines],
        }
        vals.update(kw)
        return self.env['sale.order'].create(vals)

Use in tests:

from .factories import OdooFactory

class TestMyFeature(TransactionCase):
    @classmethod
    def setUpClass(cls):
        super().setUpClass()
        cls.factory = OdooFactory(cls.env)

    def test_something(self):
        order = self.factory.sale_order(lines=[
            {'product_id': self.factory.product(list_price=200).id, 'product_uom_qty': 2}
        ])
        self.assertEqual(order.amount_untaxed, 400.0)

---

5. Template Database (conftest.py)

This is the single biggest speed optimisation. Always use it.

# conftest.py (repo root)
import os
import pytest
import psycopg2

TEMPLATE_DB = os.environ.get('TEMPLATE_DATABASE', 'odoo_primed')
PG = dict(
    host=os.environ.get('POSTGRES_HOST', 'localhost'),
    user=os.environ.get('POSTGRES_USER', 'odoo'),
    password=os.environ.get('POSTGRES_PASSWORD', 'odoo'),
    dbname='postgres',
)

@pytest.fixture(scope='class')
def clone_db(request):
    """Clone the primed template database for this test class. Drop on teardown."""
    db_name = f"test_{request.cls.__name__.lower()}_{os.getpid()}"
    conn = psycopg2.connect(**PG)
    conn.autocommit = True
    conn.execute(f"CREATE DATABASE {db_name} TEMPLATE {TEMPLATE_DB}")
    conn.close()
    yield db_name
    conn = psycopg2.connect(**PG)
    conn.autocommit = True
    conn.execute(f"DROP DATABASE IF EXISTS {db_name}")
    conn.close()

CI before_script:

before_script:
  - createdb -h postgres -U odoo odoo_primed
  - odoo -d odoo_primed -i sale,your_module --without-demo=all --stop-after-init

Expected speedup: 8–20× faster test setup (typically ~12×).

---

6. BDD with pytest-bdd

Only add BDD when stakeholders read and contribute to feature files.

6.1 Feature file

# addons/sale_loyalty/features/loyalty_discount.feature
Feature: Loyalty discount on sale orders
  As a sales manager
  I want loyalty tier discounts applied automatically
  So that high-value customers feel valued

  Scenario Outline: Discount by tier
    Given a customer with loyalty tier "<tier>"
    When I create a sale order with 1 Widget
    Then the order line discount should be <discount>%

    Examples:
      | tier   | discount |
      | gold   | 10       |
      | silver | 5        |

6.2 Step definitions

# tests/test_loyalty_bdd.py
import pytest
from pytest_bdd import scenarios, given, when, then, parsers

scenarios('../features/loyalty_discount.feature')

@pytest.fixture
def ctx():
    return {}

@given(parsers.parse('a customer with loyalty tier "{tier}"'), target_fixture='customer')
def make_customer(env, tier):
    return env['res.partner'].create({'name': f'BDD-{tier}', 'loyalty_tier': tier})

@when(parsers.parse('I create a sale order with {qty:d} Widget'))
def create_order(env, customer, qty, ctx):
    product = env['product.product'].search([('name', '=', 'Widget')], limit=1)
    ctx['order'] = env['sale.order'].create({
        'partner_id': customer.id,
        'order_line': [(0, 0, {'product_id': product.id, 'product_uom_qty': qty})],
    })

@then(parsers.parse('the order line discount should be {pct:d}%'))
def assert_discount(ctx, pct):
    assert ctx['order'].order_line[0].discount == pct

---

7. Playwright E2E

7.1 Core rules

• Maximum 10–30 scenarios. Do not grow past this.
• Run against Runboat live URLs, never bootstrap Odoo inside the CI job.
• Selectors: data-test-id on custom views, get_by_role, get_by_label.
• Never use auto-generated Odoo CSS classes (.o_form_view, .o_field_widget, etc.).
• Add data-test-id to your XML views: <field name="discount" data-test-id="line-discount"/>.
• Set default timeout ≥ 30 seconds (Odoo JS is slow to load).
• Poll BASE_URL + /web/login until 200 before the suite starts (Runboat cold-start).

7.2 Session fixture

# e2e/conftest.py
import pytest
import requests
import time

BASE_URL = os.environ['ODOO_BASE_URL']   # Set by CI from Runboat

def wait_for_odoo(url, timeout=180):
    deadline = time.time() + timeout
    while time.time() < deadline:
        try:
            r = requests.get(f"{url}/web/login", timeout=5)
            if r.status_code == 200:
                return
        except Exception:
            pass
        time.sleep(5)
    raise TimeoutError(f"Odoo at {url} not ready after {timeout}s")

@pytest.fixture(scope='session')
def browser_context_args(browser_context_args):
    wait_for_odoo(BASE_URL)
    return {**browser_context_args, 'base_url': BASE_URL}

@pytest.fixture(scope='session')
def auth_state(browser, browser_context_args):
    ctx = browser.new_context(**browser_context_args)
    page = ctx.new_page()
    page.goto('/web/login')
    page.get_by_label('Email').fill('admin')
    page.get_by_label('Password').fill('admin')
    page.get_by_role('button', name='Log in').click()
    page.wait_for_url('**/odoo/**')
    state = ctx.storage_state()
    ctx.close()
    return state

@pytest.fixture
def page(browser, browser_context_args, auth_state):
    ctx = browser.new_context(**browser_context_args, storage_state=auth_state)
    pg = ctx.new_page()
    pg.set_default_timeout(30_000)
    yield pg
    ctx.close()

7.3 Example scenario

# e2e/test_sale_order.py
from playwright.sync_api import expect

def test_gold_customer_discount_shows_in_ui(page):
    page.goto('/odoo/sales/new')
    page.get_by_label('Customer').fill('Acme Corp')
    page.get_by_role('option', name='Acme Corp').click()
    page.get_by_role('button', name='Add a product').click()
    page.get_by_label('Product').last.fill('Widget')
    page.get_by_role('option', name='Widget').click()

    expect(page.locator('[data-test-id="line-discount"]').first).to_have_text('10.00')

8. Kubernetes Test Infrastructure (ITSulu Production)

ITSulu runs tests on the production K8s cluster in the itsulu-testing namespace. Manifests live in kubernetes/itsulu-testing/ in the infrastructure repo.

8.1 Architecture

itsulu-testing namespace
├── PostgreSQL 15 (deploy-test-db.yaml)      # persistent, always running
│   └── odoo_template DB                      # primed once with all modules
├── K8s Secret: test-db-info                  # username, password, database keys
├── K8s Secret: gitlab-docker-creds           # image pull from GitLab registry
└── Job: blog-publisher-bdd-test-<timestamp>  # ephemeral per test run
    ├── initContainer: setup-test-db           # postgres:15-alpine, createdb from template
    └── container: test-runner                 # our Docker image, runs pytest

8.2 Docker Image (Dockerfile)

FROM odoo:17.0

# odoo:17.0 runs as non-root 'odoo' user — pip installs go to ~/.local
# python3 is at /usr/bin/python3; use python3 -m pytest NOT pytest (not in PATH)
RUN python3 -m pip install --no-cache-dir \
    pytest pytest-odoo pytest-bdd pytest-cov pytest-html requests

# /mnt/extra-addons must be world-writable before COPY, then owned by odoo
RUN mkdir -p /mnt/extra-addons && chmod 777 /mnt/extra-addons
COPY --chown=odoo:odoo addons/itsulu_blog_publisher /mnt/extra-addons/itsulu_blog_publisher

WORKDIR /tmp/test
CMD ["python3", "-m", "pytest", "tests/", "-v", "--html=/tmp/report.html", "--self-contained-html"]

Critical gotchas learned:

• odoo:17.0 runs as non-root odoo user — apt-get, chmod, chown fail unless done before user switch
• pip install installs to /var/lib/odoo/.local/ not system Python — run as odoo user or use --chown=odoo:odoo on COPY
• pytest is NOT in PATH for the odoo user — always use python3 -m pytest
• python is not available — use python3
• /mnt/extra-addons parent directory must exist AND be writable before COPY
• Use COPY --chown=odoo:odoo to ensure the odoo user can read files (source files with 600 perms will fail otherwise)
• Do NOT use git clone in the test runner — the base image has no git. The addon is already COPY'd into the image.
• sudo is not available in the container
• apt-get update fails due to missing /var/lib/apt/lists/partial and permission restrictions

8.3 Running a Test Job

addons/<module>/features/   Gherkin features (BDD, when used)
e2e/                        Playwright E2E scenarios
.gitlab-ci.yml              Six-stage CI pipeline

## Development workflow — STRICT TDD
1. Write a failing test. Show it to me for approval.
2. I confirm the test matches intent before you write code.
3. Write minimum code to make it pass.
4. Run the full test class. Confirm green.
5. Refactor if needed. Test stays green.
6. Run pre-commit before considering the task done.
7. Never proceed to step 3 before step 2 is complete.

## Test naming
Class:  TestXxxYyy           (describes unit under test)
Method: test_what_when_condition  (complete sentence, underscore-separated)
Good:   test_gold_tier_customer_gets_ten_percent_discount
Bad:    test_discount, test1, test_it_works

## When to use BDD
Only when a business stakeholder reads the feature file. Ask me first.
Default: TDD only with descriptive test names.

## Commands
pytest addons/                              Run all tests
pytest addons/ -k TestSaleOrderDiscount     Run one class
pytest addons/ -m "not slow"                Exclude tagged tests
pytest e2e/ --base-url=$BUILD_URL           E2E against Runboat
pre-commit run --all-files                  Lint + format

## Patterns to follow
- Use OdooFactory from tests/factories.py for record creation
- Use assertQueryCount on hot paths (confirm budget with me first)
- Add data-test-id to custom view fields used by Playwright
- One assertion per test method (exceptions need justification)

## Patterns to avoid
- Never create records using demo data or pre-seeded fixtures
- Never bypass pre-commit hooks
- Never silence test failures with try/except or xfail without issue ref
- Never write "assert True" or trivially-passing tests
- Never combine setup + assertion in one line

## When in doubt
Stop and ask me before: creating a new addon, modifying __manifest__,
changing a model that another module inherits, any sudo() or ir.rule change.
Show options with trade-offs. I will choose.

11.5 Odoo 17 Model Field Compatibility

When extending core Odoo models (e.g., blog.post), be aware of field differences:

Model	Field	Odoo 16	Odoo 17	Note
blog.post	body_arch	Yes	No	XML layout field; removed in Odoo 17
blog.post	body	Yes	No	HTML body field; use editor interface instead
blog.post	itsulu_social_id	N/A	Custom	Add via _inherit for reverse relationship to custom models
mail.template	Subject/Body	Mako syntax	Mako syntax	Renders async in send_mail(); use Mako % for loops, not method calls in templates

Pattern for extending blog.post safely:

# addons/<module>/models/blog_post.py
class BlogPost(models.Model):
    _inherit = 'blog.post'
    
    custom_field_id = fields.One2many(
        comodel_name='custom.model',
        inverse_name='blog_post_id',
        string='Custom Records',
    )

Pattern for creating blog.post test records:

# Use sudo() to bypass Odoo validation when creating minimal test posts
post = self.env['blog.post'].sudo().create({
    'name': 'Test Post',
    'blog_id': blog.id,
    'is_published': True,
    # Do NOT include body, body_arch, or body_html — use website editing UI
})

12. Failure Recovery Quick Reference

Symptom	Most likely cause	Fix
All tests fail with relation does not exist	Template DB corrupted / stale	Rebuild: dropdb odoo_primed && createdb odoo_primed && odoo -d odoo_primed -i ...
E2E first scenario fails, rest pass	Runboat not ready	Add readiness poll: curl -sf $URL/web/login || sleep 5 in a loop
E2E selector breaks after Odoo update	Auto-generated class changed	Replace with data-test-id attribute or get_by_role
Pipeline stuck "initializing"	Runboat cluster resource exhaustion	Increase namespace ResourceQuota; close stale MRs
Flaky test fails > twice/week	Non-deterministic test	Quarantine with @pytest.mark.skip(reason="flaky #123"); fix within 1 week
Secret appears in CI logs	Variable not masked	Rotate immediately; add to masked variables in GitLab
ArgoCD stuck OutOfSync	Manual cluster change	argocd app diff; revert manual change; re-sync
K8s Job: PermissionError: __manifest__.py	Files copied without --chown=odoo:odoo	Rebuild image with COPY --chown=odoo:odoo in Dockerfile
K8s Job: No module named pytest	Ran as wrong user (root); pytest in odoo user's ~/.local	Run container as odoo user (default); use python3 -m pytest not pytest
K8s Job: database does not exist	Init container used $RANDOM — different from test-runner	Use fixed DB name (odoo_test) shared between containers
K8s Job: ErrImagePull	gitlab-docker-creds secret missing or expired	Recreate: kubectl create secret docker-registry gitlab-docker-creds ...
K8s Job: CreateContainerConfigError	Secret key missing (e.g. database key not in test-db-info)	kubectl describe pod <pod> to find missing key; recreate secret with all 3 keys
Docker build: chmod: Operation not permitted	odoo:17.0 runs as non-root; can't chmod after COPY	Do chmod 777 /mnt/extra-addons BEFORE COPY, then use --chown=odoo:odoo on COPY
Docker build: apt-get: Permission denied	Base image runs as non-root; apt requires root	odoo:17.0 has no apt access — use python3 -m pip instead; no system packages possible
Mail test: mail.mail.body_html is empty after send_mail()	Template rendering is async; test checks mail.mail synchronously	Use force_send=True in send_mail(); check mail.outgoing state or delay assertion; or manually render template with Mako before creating mail.mail
Mail test: mail.mail.subject is False instead of string	Template subject field not rendered by send_mail()	Verify template fields are populated in DB; render manually if needed
Odoo 17: blog.post doesn't accept body or body_arch fields	Fields renamed/removed in Odoo 17	Use factory pattern with .sudo().create() to bypass validation; post content should be managed via editor interface, not direct assignment
Odoo 17: Inverse relationship not loaded in template context	Relations lazy-load; mail.template context may not include reverse relations	Use explicit search in Mako (for loop) instead of relying on inverse field; or fetch record with prefetch in the render context
Test: IndexError: tuple index out of range when accessing mock.call_args[0][0]	Mock method called with keyword-only args; call_args[0] is empty tuple ()	Use mock.call_args[1].get('key') for kwargs; or check mock.called before accessing call_args
Test: TransactionCase gets InFailedSqlTransaction in subsequent tests	Previous test called self.env.cr.commit() breaking savepoint chain	Replace commit() with flush_all() in code being tested; commit() is only allowed in non-test code in production

13. SLO Targets

Metric	Target	Why
Unit test suite duration	< 3 min	Keeps TDD cycles tight
Full pipeline P50	< 15 min	Fast enough to wait for
Full pipeline P95	< 25 min	Outliers do not ruin the day
Flaky test rate	< 2%/week	Maintains trust in suite
Coverage on new code	≥ 80%	Enforces test-first habit
Runboat cold-start P95	< 120 s	E2E does not time out
Production deploy MTTR	< 15 min	Git revert + ArgoCD sync

14. Phased Adoption Triggers

Add Phase 2 (BDD, factories, coverage gates) when ≥ 2:

• Stakeholders ask "how do we know X works?"
• Tests break on demo-data changes, not code changes
• Production N+1 regression caught post-deploy
• Coverage < 60% on touched files

Add Phase 3 (Runboat) when ≥ 2:

• Stakeholder asks "can I see it before merge?"
• Staging environment contention costs developer time
• Bugs escape CI that a human click-through would catch

Add Phase 4 (Playwright, migration testing) when ≥ 2:

• Production incident that automated testing would have caught
• Odoo upgrade requires emergency rollback
• Team says "I don't trust the test suite"
