Testing
=======
Tryton supports both functional and unit tests.
Testing your module
~~~~~~~~~~~~~~~~~~~
Functional tests
----------------
Functional tests are written as doctests_ using proteus.
Unit tests
----------
Tryton provides the :class:`ModuleTestCase` class that bundles a set of tests
that are useful for every module.
Unit tests in ``ModuleTestCase`` can be decorated with
:func:`trytond.tests.test_tryton.with_transaction` to run the test in a
transaction.
To use it in your own module you just have to inherit from
:class:`ModuleTestCase` and set the class attribute
:attr:`module <ModuleTestCase.module>` to the name of your module.
.. highlight:: python
::
from trytond.tests.test_tryton import ModuleTestCase, with_transaction
class MyModuleTestCase(ModuleTestCase):
"My Module Test Case"
module = 'my_module'
@with_transaction()
def test_method(self):
"Test method"
self.assertTrue(True)
Tests from this modules are found by the function
``trytond.modules.my_module.tests.suite`` which must return a
``unittest.TestSuite`` containing all the module's tests. This function is
called by the Tryton test runner script to gather all the tests.
A typical ``suite()`` function thus looks like this:
.. highlight:: python
::
def suite():
suite = trytond.tests.test_tryton.suite()
suite.addTests(unittest.TestLoader().loadTestsFromTestCase(
MyModuleTestCase))
suite.addTests(doctest.DocFileSuite('scenario_my_module.rst',
tearDown=doctest_teardown, encoding='utf-8',
optionflags=doctest.REPORT_ONLY_FIRST_FAILURE,
checker=doctest_checker))
return suite
.. _doctests: https://docs.python.org/library/doctest.html
.. _unittest: https://docs.python.org/library/unittest.html
Running your module's tests
---------------------------
Tryton provides the script ``trytond/tests/run-tests.py``, just invoke it like
that::
run-tests.py -m my_module
Testing trytond
~~~~~~~~~~~~~~~
Extending tests
---------------
Python modules extending tryton core can define additional tests that should be
added to the existing ones.
Those modules must create an entry point ``trytond.tests``. Any file in the
module path specified by this entry point starting with ``test_`` and ending by
``.py`` will be imported. Each of those file must define a ``suite()`` function
that returns a ``unittest.TestSuite`` that will be included in the trytond test
suite. If the module from the entry point defines a ``register`` function it
will be called when registering the test-specific models in the
:class:`trytond.pool.Pool`.
Running trytond tests
---------------------
You should use the script ``trytond/tests/run-tests.py`` by invoking it like
that::
run-tests.py [-c configuration]
You can use a different configuration file to check trytond against different
backend.
