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 preferred way to write tests in Django is using the :mod:`unittest` module
|
|
built-in to the Python standard library. This is covered in detail in the
|
|
:doc:`overview` 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
|
|
:ref:`other-testing-frameworks` section of :doc:`advanced`.
