Chapter 1. Beginning Testing
You’ve heard about the benefits of testing. You know that it can improve your code’s reliability and maintainability as well as your development processes. You may even know about the wide range of available modules and idioms that Perl offers for testing Perl and non-Perl programs. In short, you may know everything except where to start.
The labs in this chapter walk through the most basic steps of running and writing automated tests with Perl. By the end of the chapter, you’ll know how to start and continue testing, how Perl’s testing libraries work, and where to find more libraries to ease your workload.
Installing Test Modules
One of Perl’s greatest strengths is the CPAN, an archive of thousands of reusuable code libraries—generally called modules—for almost any programming problem anyone has ever solved with Perl. This includes writing and running tests. Before you can use these modules, however, you must install them. Fortunately, Perl makes this easy.
How do I do that?
The best way to install modules from the CPAN is through a packaging system that can handle the details of finding, downloading, building, and installing the modules and their dependencies.
Through the CPAN shell
On Unix-like platforms (including Mac OS X) as well as on Windows platforms if you have a C compiler available, the easiest way to install modules is by using the CPAN module that comes with Perl. To install a new version of the Test::Simple distribution, launch the CPAN shell ...
