Django 1.1 Testing and Debugging

Overview of this book

Bugs are a time consuming burden during software development. Django's built-in test framework and debugging support help lessen this burden. This book will teach you quick and efficient techniques for using Django and Python tools to eradicate bugs and ensure your Django application works correctly. This book will walk you step by step through development of a complete sample Django application. You will learn how best to test and debug models, views, URL configuration, templates, and template tags. This book will help you integrate with and make use of the rich external environment of test and debugging tools for Python and Django applications. The book starts with a basic overview of testing. It will highlight areas to look out for while testing. You will learn about different kinds of tests available, and the pros and cons of each, and also details of test extensions provided by Django that simplify the task of testing Django applications. You will see an illustration of how external tools that provide even more sophisticated testing features can be integrated into Django's framework. On the debugging front, the book illustrates how to interpret the extensive debugging information provided by Django's debug error pages, and how to utilize logging and other external tools to learn what code is doing.

Summary


We have now come to the end of discussing Django's unit test extensions to support testing web applications. In this chapter, we:

  • Learned how to organize unit tests into separate files instead of placing everything into a single tests.py file

  • Began to develop views for the survey application, and learned how to use Django's unit test extensions to test these views

  • Saw how to customize the admin interface by providing custom validation for one of our models, and learned how to test that admin customization

  • Briefly discussed some unit test extensions provided by Django that we did not encounter in any of our example tests

  • Learned when it might be necessary to use TransactionTestCase instead of TestCase for a test

While we have covered a lot of ground in learning how to test a Django application, there are many aspects to testing a web application that we have not even touched on yet. Some of these are more appropriately tested using tools other than Django itself. The next chapter will...
