Perl Testing

Is there any sexier topic in software development than software testing? That is, besides game programming, 3D graphics, audio, high-performance clustering, cool websites, et cetera? Okay, so software testing is low on the list. And that's unfortunate, because good software testing can increase your productivity, improve your designs, raise your quality, ease your maintenance burdens, and help to satisfy your customers, coworkers, and managers. Perl has a strong history of automated tests. A very early release of Perl 1.0 included a comprehensive test suite, and it's only improved from there. Learning how Perl's test tools work and how to put them together to solve all sorts of previously intractable problems can make you a better programmer in general. Besides, it's easy to use the Perl tools described to handle all sorts of testing problems that you may encounter, even in other languages. Like all titles in O'Reilly's Developer's Notebook series, this "all lab, no lecture" book skips the boring prose and focuses instead on a series of exercises that speak to you instead of at you. Perl Testing: A Developer's Notebook will help you dive right in and: Write basic Perl tests with ease and interpret the results Apply special techniques and modules to improve your tests Bundle test suites along with projects Test databases and their data Test websites and web projects Use the ""Test Anything Protocol"" which tests projects written in languages other than Perl With today's increased workloads and short development cycles, unit tests are more vital to building robust, high-quality software than ever before. Once mastered, these lessons will help you ensure low-level code correctness, reduce software development cycle time, and ease maintenance burdens. You don't have to be a die-hard free and open source software developer who lives, breathes, and dreams Perl to use this book. You just have to want to do your job a little bit better.

"Perl Testing bietet eine kompakte und umfassende Einführung ins Thema, wobei theoretische Betrachtungen [...] außen vor bleiben. [...] für einen schnellen Einstieg in dieses häufig etwas vernachlässigte Thema ist er aber genau richtig." - Dr. Peter Dintelmann, iX 2/2006

"This book in Notebook Style has a very structured format which makes it easy to learn the topic step-by-step and to get support to many questions. [...] This book fills a gap since in system programming - one of the central areas Perl is used - structured coding and testing code is often neglected. The sections "How do I do that", "What just happened", and especially "What about" in FAQ-style cover most of the details and questions of the discussed topic in a very structured and easy-to-understand manner. [...]"

Ian Langworth has been using Perl since 1997, and actively involved in the Perl community since 2003. In 2004 he contributed Apache-TinyCP and several Kwiki modules to CPAN, and spoke at Perl-related conferences such as YAPC, Usenix, and LISA. chromatic is the technical editor of the O'Reilly Network, specializing in programming, Linux(R), and open source development. He's also been known to evangelize to his co-workers toward better development practices. chromatic has occasionally produced startling numbers of test suites -- and a few testing modules -- for projects including Perl 5, Perl 6, and Parrot. Someday, he'd like to claim some responsibility for improving the quality of all software, by writing articles, producing good code, giving interesting talks, and developing better tools. He lives west of Portland, Oregon with a creek in his backyard and a park one house over. It's too late for him to choose a more realistic-sounding pen name.
