Summary
In this chapter, we introduced the core
JU
nit concepts and classes. We showed you
how to fuse a test class, a
Suite
, and a
Runner
.
Use a test class to test one domain object where each test method focuses on one
domain method or a specific set of methods.
JU
nit 4 makes extensive uses of annota-
tions to define and manage tests.
JU
nit 4 has made obsolete the
JU
nit 3 requirement
of making a test class a
TestCase
subclass.
You use a test suite to group related test classes together, allowing you to invoke
them as a group. You can even group suites together in higher-level suites.
You use a
Runner
to invoke unit tests and test suites.
In the next chapter, we introduce the Controller design pattern and build a sam-
ple Controller component application that we test with
JU
nit. This way, we not only
show you how to use the
JU
nit components we've been discussing so far, but we also
introduce many
JU
nit best practices.
