Generating parsers automatically There are tools that can generate a parser.

Note that this method does not setup a test database, so the following will be run against the existing database and the output may differ slightly depending on what questions you already created. Next we need to import the test client class later in tests. In Tutorial 4 we introduced a class-based view, based on ListView: First we need to add an import: Note that the django.

TestCase class provides some additional assertion methods. In these examples, we Writing software renderer assertContains and assertQuerysetEqual. In effect, we are using the tests to tell a story of admin input and user experience on the site, and checking that at every state and for every new change in the state of the system, the expected results are published.

So we need to add a similar constraint to DetailView: We could also improve our application in other ways, adding tests along the way.

So, our views could check for this, and exclude such Questions. Perhaps logged-in admin users should be allowed to see unpublished Questions, but not ordinary visitors. At a certain point you are bound to look at your tests and wonder whether your code is suffering from test bloat, which brings us to: At this rate there will soon be more code in our tests than in our application, and the repetition is unaesthetic, compared to the elegant conciseness of the rest of our code.

For the most part, you can write a test once and then forget about it.

It will continue performing its useful function as you continue to develop your program. Sometimes tests will need to be updated. Suppose that we amend our views so that only Questions with Choices are published. In that case, many of our existing tests will fail - telling us exactly which tests need to be amended to bring them up to date, so to that extent tests help look after themselves.

At worst, as you continue developing, you might find that you have some tests that are now redundant. Good rules-of-thumb include having: These tools allow you to check not just the behavior of your Django code, but also, for example, of your JavaScript. If you have a complex application, you may want to run tests automatically with every commit for the purposes of continuous integrationso that quality control is itself - at least partially - automated.

A good way to spot untested parts of your application is to check code coverage. This also helps identify fragile or even dead code. Coverage will help to identify dead code.
