3430 4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	6 to the ecosystem, you should use them to check that your modification is not breaking
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	7 anything, and if possible you should extend them to cover any new feature.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	14 Tests are run using `pytest`_ and are located in the ``tests`` directory.
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	15 You'll also find legacy tests in ``sat/test`` but those one are old, not maintained and
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	16 only kept there temporarily until they are ported to the new system.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	18 For now, emphasis is put on end-2-end tests, as they are covering the whole ecosystem, and
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	19 are quite easy to write. The downside is that they are quite long to run.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	21 Several `fixtures`_ are available in the various ``conftest.py`` files, it's a good idea
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	22 to have an overview of them if you're willing to write your own tests.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	31 environment managed through Docker. The ``docker/docker-compose_e2e.yml`` is used to

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	34 A script is available at ``tests/e2e/run_e2e.py`` to launch the tests. It will create the
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	35 containers, bind the current code to them, and set environment variables according to
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	36 arguments.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	38 The arguments set to this script are the ``pytest`` options, thus you can have a verbose
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	39 mode with ``-v`` and select specific test with ``-k EXPRESSION`` (see ``pytest --help`` for

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	159 variable), to automatically modify and/or check the text sent by a command. You can
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	160 specify Python code to execute to modify the received text with the ``set_filter``
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	161 method (this code is in a string which will be executed by Python interpreter, where the
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	162 ``content`` variable is the received text). By default, the text is kept unmodified.

4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	175 To make the tests as easy to write as possible, and as natural to read as possible, the
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	176 higher level `Helium`_ Python module is used. Thanks to it, the tests can read pretty much
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	177 like instructions we would give to a human user. Helium makes also easy to do some tasks
4ba31dd1f0f5 doc: documentation for testing in new `contributing` section Goffi <goffi@goffi.org> parents: diff changeset	178 more complicated with Selenium alone, like dropping a file to an element.
