Testing

Introduction

django-guardian is extending capabilities of Django’s authorization facilities and as so, it changes it’s security somehow. It is extremaly important to provide as simplest API Reference as possible.

According to OWASP, broken authentication is one of most commonly security issue exposed in web applications.

Having this on mind we tried to build small set of necessary functions and created a lot of testing scenarios. Neverteless, if anyone would found a bug in this application, please take a minute and file it at issue-tracker.

Running tests

Tests are run by Django’s buildin test runner. To call it simply run:

$ python setup.py test

or inside a project with guardian set at INSTALLED_APPS:

$ python manage.py test guardian

Coverage support

Coverage is a tool for measuring code coverage of Python programs. It is great for tests and we use it as a backup - we try to cover 100% of the code used by django-guardian. This of course does NOT mean that if all of the codebase is covered by tests we can be sure there is no bug (as specification of almost all applications requries some unique scenarios to be tested). On the other hand it definitely helps to track missing parts.

To run tests with coverage support and show the report after we have provided simple bash script which can by called by running:

$ ./run_test_and_report.sh

Result should be somehow similar to following:
