Writing tests

In this documentation we will inform you about basic structure where implement code and some structure and objects you can use.

Please feel free to update this documentation because it will help others ppl a lot!

Pytest marks

We have predefined some of pytest marks you can use to decorate your tests. You can find them defined in pytest.ini where we inform pytest about those marks.

We have markers defined in pytest_customization package under marks.py plugin. From your tests you can import directly from ocsci.testlib module with this statement: from ocsci.testlib import tier1 for example.

Bugzilla decorator

You can mark test with specific bugzilla decorator as you can see in following example: :

import pytest

from ocs_ci.framework.testlib import bugzilla, ManageTest

@bugzilla('1726266')
class TestPvCreation(ManageTest):
    pass


# or you can directly use pytest.mark like:
@pytest.mark.bugzilla('bugzilla_id')  # where bugzilla_id can be e.g. 1726266
    pass

For more details what else is possible with pytest_marker_bugzilla plugin look at the project documentation.

Skipping tests based on ocs version

You can skip a test which is not applicable for specific ocs version using

@skipif_ocs_version([expression1, expression2, ...]) decorator.

example:

from ocs_ci.framework.testlib import skipif_ocs_version

@skipif_ocs_version(['>4.1','<4.3'])
def test_fio_workload():
    pass

You can also specify a single expression in a string like:

@skipif_ocs_version('<4.3')
def test_fio_workload():
    pass

Base test classes for teams

Those are located in testlib.py which you can also import from ocsci.testlib module with statement: from ocsci.testlib import manage which is base test class for manage team.

Constants and Defaults

Many of our tests utilize defaults and constants. These are both defined in ocs/constants.py and ocs/defaults.py respectively. Constants and defaults are fairly similar but functionally different which is why we have chosen to separate them into their own modules.

If your test requires one of these you can easily import it. If you intend to implement a new one (generally if more than one test will utilize it), please consider whether or not that value might change between different test executions. If it's something like a filepath (unchanging), it's probably a constant. If tests may overwrite the value, it's most likely a default.

Note these modules are not intended to be a dumping ground for any variable your test might need. These are designed to be homes for widely used variables that need to be consistent across a test execution. You can learn more from viewing the existing constants and defaults in their respective modules.

Fixture usage

It's documented here.

Other notes

Of course you can import in one line both team base class and marker with statement: from ocsci.testlib import manage, tier1
