This document discusses Django testing tools including: 1. Using "manage.py test" to run tests for applications or the entire site. Tests are defined in <app>/tests.py files. 2. Fixtures allow loading initial data from JSON files to use in tests. Fixtures are specified in the TestCase class. 3. The Client allows making requests like GET and POST to test views and check responses. Client stores session data between requests.
