+===============
+Testing Modules
+===============
+
+Odoo provides support for testing modules using unittest2_.
+
+To write tests, simply define a ``tests`` sub-package in your module, it will
+be automatically inspected for test modules. Test modules should have a name
+starting with ``test_`` and should be imported from ``tests/__init__.py``,
+e.g.
+
+.. code-block:: text
+
+    your_module
+    |-- ...
+    `-- tests
+        |-- __init__.py
+        |-- test_bar.py
+        `-- test_foo.py
+
+and ``__init__.py`` contains::
+
+    from . import test_foo, test_bar
+
+.. note:: test modules which are not imported from ``tests/__init__.py`` will
+          not be run
+
+The test runner will simply run any test case, as described in the official
+`unittest documentation`_, but Odoo provides a number of utilities and helpers
+related to testing Odoo content (modules, mainly):
+
+.. autoclass:: openerp.tests.common.TransactionCase
+    :members: browse_ref, ref
+
+.. autoclass:: openerp.tests.common.SingleTransactionCase
+    :members: browse_ref, ref
+
+By default, tests are run once right after the corresponding module has been
+installed. Test cases can also be configured to run after all modules have
+been installed, and not run right after the module installation:
+
+.. autofunction:: openerp.tests.common.at_install
+
+.. autofunction:: openerp.tests.common.post_install
+
+The most common situation is to use
+:class:`~openerp.tests.common.TransactionCase` and test a property of a of a
+model in each method::
+
+    class TestModelA(common.TransactionCase):
+        def test_some_action(self):
+            record = self.env['model.a'].create({'field': 'value'})
+            record.some_action()
+            self.assertEqual(
+                record.field,
+                expected_field_value)
+
+        # other tests...
+
+Running tests
+-------------
+
+Tests are automatically run when installing or updating modules if
+:option:`--test-enable <odoo.py --test-enable>` was enabled when starting the
+Odoo server.
+
+As of Odoo 8, running tests outside of the install/update cycle is not
