Mastering Django: Core

Basic testing strategies

There are many ways to approach writing tests. Some programmers follow a discipline called test-driven development; they actually write their tests before they write their code. This might seem counter-intuitive, but in-fact, it's similar to what most people will often do anyway: they describe a problem, then create some code to solve it.

Test-driven development simply formalizes the problem in a Python test case. More often, a newcomer to testing will create some code and later decide that it should have some tests. Perhaps it would have been better to write some tests earlier, but it's never too late to get started.
