Odoo's Test Framework - Learn Best Practices

Odoo's Test Framework - Learn Best Practices

• 2.
  A good testsuite really is an executable specification.
• 3.
  Test-driven development (TDD) whilenot finished: test = Test() assert not test() code.write() assert test() while test() and code.canBeBetter(): code.refactor()
• 4.
  Odoo’s test classes ●Inherit from unittest’s TestCase ● Manage a database cursor ● Performed on an Odoo database
• 5.
  TransactionCase Each method isrun in its own transaction. The transaction cursor is not committed. SavepointCase All methods are run in a single transaction. Each method is guarded by a savepoint (like a sub-transaction). setUpClass() setUp() test_method1() tearDown() setUp() test_method2() tearDown() ... tearDownClass() setUpClass() setUp() test_method1() tearDown() setUp() test_method2() tearDown() ... tearDownClass()
• 6.
  HttpCase, HttpSavepointCase ● Launches ○the HTTP server ○ a Chrome browser (headless) ● Open any URL ● Run some JavaScript in the Odoo client
• 7.
  Available on testinstances self.registry self.cr self.uid self.env
• 8.
  Server-side form ● APython implementation of a form ● Reproduces what the client-side form does ● Create or edit a record «just like a user would»
• 9.
  Server-side form move_form =Form(self.env['account.move']) move_form.partner_id = partner ... with move_form.invoice_line_ids.new() as line_form: line_form.product_id = product ... invoice = move_form.save()
• 10.
  Server-side form with Form(invoice)as move_form: move_form.partner_id = partner ... with move_form.invoice_line_ids.edit(0) as line_form: line_form.product_uom_id = uom ...
• 11.
  Use addCleanup() def setUp(self): super().setUp() self.registry= odoo.registry(get_db_name()) self.addCleanup(self.registry.reset_changes) self.addCleanup(self.registry.clear_caches) #: current transaction's cursor self.cr = self.cursor() self.addCleanup(self.cr.close) #: :class:`~odoo.api.Environment` for the current test case self.env = api.Environment(self.cr, odoo.SUPERUSER_ID, {}) self.addCleanup(self.env.reset)
• 12.
  Use unittest.mock from datetimeimport date from unittest.mock import patch day = date(1979, 5, 4) with patch.object(fields.Date, 'today', lambda *args, **kwargs: day): ... assert fields.Date.today() == day ...
• 13.
  Maximize coverage ● Everycorner case ● Different users ● Access errors ● Expected errors
