Testing in Django

Automated testing is an extremely useful bug-killing tool for the modern Web developer. You can use a collection of tests – a test suite – to solve, or avoid, a number of problems:

  • When you’re writing new code, you can use tests to validate your code works as expected.
  • When you’re refactoring or modifying old code, you can use tests to ensure your changes haven’t affected your application’s behavior unexpectedly.

Testing a Web application is a complex task, because a Web application is made of several layers of logic – from HTTP-level request handling, to form validation and processing, to template rendering. With Django’s test-execution framework and assorted utilities, you can simulate requests, insert test data, inspect your application’s output and generally verify your code is doing what it should be doing.

The best part is, it’s really easy.

Where to go from here

The preferred way to write tests in Django is using the unittest module built in to the Python standard library. This is covered in detail in the Testing Django applications document.

You can also use any other Python test framework; Django provides an API and tools for that kind of integration. They are described in the Using different testing frameworks section of Advanced testing topics.
