Perl has a rich vocabulary, but you can accomplish many things using only a fraction of the power available. In the same way, Perl has an ever-increasing number of testing modules and best practices built around the simple ok( ) function described in Chapter 1.
The labs in this chapter guide you through the advanced features of Test::More and other commonly used testing modules. You'll learn how to control which tests run and why, how to compare expected and received data effectively, and how to test exceptional conditions. These are crucial techniques that provide the building blocks for writing comprehensive test suites.
