Testing: Application Tests¶
The application test suite uses:
The application tests consist of unit tests for the Python application code and functional tests that verify the functionality of the application code from the perspective of the user through a web browser.
The functional tests use an outdated version of Firefox chosen specifically for compatibility with Selenium 2, and a rough approximation of the most recent Tor Browser.
We’re working on running the Selenium tests in Tor Browser. See GitHub #1629 for more info.
The application tests are installed automatically in the development
and app-staging VMs, based on the contents of
If you wish to change the dependencies, see Upgrading or Adding Python Dependencies.
Running the application tests¶
The tests can be run inside the development VM:
vagrant ssh development cd /vagrant/securedrop pytest -v tests
Or the app-staging VM:
vagrant ssh app-staging sudo su www-data -s /bin/bash cd /var/www/securedrop pytest -v tests
For explanation of the difference between these machines, see Virtual Environments.
If you just want to run the functional tests, you can use:
pytest -v tests/functional/
Similarly, if you want to run a single test, you can specify it through the file, class, and test name:
Updating the application tests¶
Unit tests are stored in the
securedrop/tests/ directory and functional
tests are stored in the functional test directory:
securedrop/tests/ ├── functional │ ├── test_admin_interface.py │ ├── test_submit_and_retrieve_file.py │ │ ... │ └── submission_not_in_memory.py ├── utils │ ├── db_helper.py │ ├── env.py │ └── async.py ├── test_journalist.py ├── test_source.py │ ... └── test_store.py
securedrop/tests/utils contains helper functions for writing tests.
If you want to add a test, you should see if there is an existing file
appropriate for the kind of test, e.g. a new unit testing
should go in
