The document is about a mini-course on test-driven development in Rails. It discusses topics like what and how to test, when to write tests, how many assertions per test. It provides context on unit, integration, view and other types of tests. It explains the test-first development cycle of developing, testing, developing more while testing continuously. Code examples are given of a test class and method for a Roman numeral conversion method.

66

104. Test fixture refers to the fixed
state used as a baseline for
running tests in software testing.
The purpose of a test fixture is to
ensure that there is a well known
and fixed environment in which
tests are run so that results are
repeatable. Some people call this
the test context.

204. Mocks Aren't Stubs
The term 'Mock Objects' has become a popular one to
describe special case objects that mimic real objects for
testing. Most language environments now have frameworks
that make it easy to create mock objects. What's often not
realized, however, is that mock objects are but one form of
special case test object, one that enables a different style of
testing. In this article I'll explain how mock objects work,
how they encourage testing based on behavior verification,
and how the community around them uses them to develop
a different style of testing.
