Description

Testing was once regarded as a separate and unique discipline within the overallsoftware development process. The reality today is that a growing number ofprojects are spreading the responsibility of testing among more members of theteam. In other words, testing is no longer limited to testers. This new bookintroduces Fit: a proven, effective, and powerful open source framework forautomating the software testing process. Fit (Framework for IntegratedTesting) is vendor-independent and widely praised for its practicality. Eachteaching point of Fit is backed up by supremely useful examples, and RickMugridge and Ward Cunningham (the founder of Fit) offer advice on how tomake Fit digestible to all members of a development team. The result is a costefficientframework that will allow organizations to deliver better software in amore timely fashion.

Back cover copy

The unique thing about Fit for Developing Software is the way it addresses the interface between customers/testers/analysts and programmers. All will find something in the book about how others wish to be effectively communicated with. A Fit book for programmers wouldn't make sense because the goal is to create a language for business-oriented team members. A Fit book just for businesspeople wouldn't make sense because the programmers have to be involved in creating that language. The result is a book that should appeal to a wide range of people whose shared goal is improving team communications.

--Kent Beck, Three Rivers Institute

Even with the best approaches, there always seemed to be a gap between the software that was written and the software the user wanted. With Fit we can finally close the loop. This is an important piece in the agile development puzzle.

--Dave Thomas, coauthor of The Pragmatic Programmer

Ward and Rick do a great job in eschewing the typical, overly complicated technology trap by presenting a simple, user-oriented, and very usable technology that holds fast to the agile principles needed for success in this new millennium.

--Andy Hunt, coauthor of The Pragmatic Programmer

Florida Tech requires software engineering students to take a course in programmer testing, which I teach. Mugridge and Cunningham have written a useful and instructive book, which will become one of our course texts.

--Cem Kaner, Professor of Software Engineering, Florida Institute of Technology

Rick and Ward continue to amaze me. Testing business rules is a fundamentally hard thing that has confounded many, and yet these two have devised a mechanism that cuts to the essence of the problem. In this work they offer a simple, thorough, approachable, and automatable means of specifying and testing such rules.

--Grady Booch, IBM Fellow

By providing a simple, effective method for creating and automating tabular examples of requirements, Fit has dramatically improved how domain experts, analysts, testers, and programmers collaborate to produce quality software.

--Joshua Kerievsky, founder, Industrial Logic, Inc., and author of Refactoring to Patterns

Agile software development relies on collaborating teams, teams of customers, analysts, designers, developers, testers, and technical writers. But, how do they work together? Fit is one answer, an answer that has been thoroughly thought through, implemented, and tested in a number of situations. Primavera has significantly stabilized its product lineusing Fit, and I'm so impressed by the results that I'm suggesting it to everyone I know. Rick and Ward, in their everlasting low-key approach, have again put the keystone in the arch of software development. Congratulations and thanks from the software development community.

--Ken Schwaber, Scrum Alliance, Agile Alliance, and codeveloper of Scrum

Fit is the most important new technique for understanding and communicating requirements. It's a revolutionary approach to bringing experts and programmers together. This book describes Fit comprehensively and authoritatively. If you want to produce great software, you need to read this book.

--James Shore, Principal, Titanium I.T. LLC

There are both noisy and quiet aspects of the agile movement and it is often the quieter ones that have great strategic importance. This book by Ward and Rick describes one of these absolutely vital, but often quieter, practices--testing business requirements. A renewed focus on testing, from test-driven development for developers to story testing for customers, is one of the agile community's great contributions to our industry, and this book will become one of the cornerstones of that contribution. Stories are done-done (ready for release) when they have been tested by both developers (done) and customers (d
