|
Testing
|
|
=======
|
|
|
|
With `tox <https:///tox.wiki>`_ the whole test suite can be executed in
|
|
a separate *virtual environment* for each supported Python version available on
|
|
the system. ``tuf`` and its dependencies are installed automatically for each
|
|
tox run.
|
|
|
|
::
|
|
|
|
$ tox
|
|
|
|
Below, you will see more details about each step managed by ``tox``, in case
|
|
you need debug/run outside ``tox``.
|
|
|
|
Unit tests
|
|
----------
|
|
|
|
More specifically, the Update Framework's test suite can be executed by invoking
|
|
the test aggregation script inside the *tests* subdirectory. ``tuf`` and its
|
|
dependencies must already be installed.
|
|
::
|
|
|
|
$ cd tests/
|
|
$ python3 aggregate_tests.py
|
|
|
|
|
|
Individual tests can also be executed. Optional ``-v`` flags can be added to
|
|
increase log level up to DEBUG (``-vvvv``).
|
|
::
|
|
|
|
$ cd tests/
|
|
$ python3 test_updater_ng.py -v
|
|
|
|
|
|
Coverage
|
|
--------
|
|
|
|
To run the tests and measure their code coverage, the aggregation script can be
|
|
invoked with the ``coverage`` tool (requires installation of ``coverage``, e.g.
|
|
via PyPI).
|
|
::
|
|
|
|
$ cd tests/
|
|
$ coverage run aggregate_tests.py && coverage report
|
|
|
|
|
|
Auto-formatting
|
|
---------------
|
|
|
|
CI/CD will check that new TUF code is formatted with `black
|
|
<https://black.readthedocs.io/>`__ and `isort <https://pycqa.github.io/isort>`__.
|
|
Auto-formatting can be done on the command line:
|
|
::
|
|
|
|
$ black <filename>
|
|
$ isort <filename>
|
|
|
|
or via source code editor plugin
|
|
[`black <https://black.readthedocs.io/en/stable/editor_integration.html>`__,
|
|
`isort <https://github.com/pycqa/isort/wiki/isort-Plugins>`__] or
|
|
`pre-commit <https://pre-commit.com/>`__-powered git hooks
|
|
[`black <https://black.readthedocs.io/en/stable/version_control_integration.html>`__,
|
|
`isort <https://pycqa.github.io/isort/docs/configuration/pre-commit/>`__].
