It’s very easy not to write a book.

Mostly since it’s such an awful lot of work. You’ll first need to figure out what you’re going to write about, and find an angle that makes it interesting enough for potential readers to buy the book and spend the time to finish it. The writing itself is hard work as well, and may take several years. Along the way you’ll be telling yourself things that will keep you from finishing the task: I’m not doing anything original here. Nobody will be interested. Somebody else wrote a better book about this than I could ever do. If I don’t cover topic B as well, it’s not going to be a useful book at all.

During the holiday I read a book mentioned to me by Pim Elshoff: “Skin in the game”, by Nassim Nicholas Taleb. Discussing this concept of “skin in the game” with Pim had made me curious about the book. It’s not such a fat book as one of Taleb’s other books, which is possibly more famous, called “Antifragile”. “Skin in the game” is a much lighter book, and also quite polemic, making it an often uncomfortable, but fun reading experience. I can easily see how people could get mad about this book or aggressive towards its author (not that I’m encouraging or approving of that aggression!). While reading it, it reminded me of Nietzsche, and his despise of the “common man”, who Taleb calls “the intellectual” - someone who has no “skin in the game”, let alone “soul in the game”. Taleb’s ideas are interesting, just like Nietzsche’s are, but they could easily be abused, and probably so by misinterpreting them.

This article is part 2 of my review of the book “Fifty quick ideas to improve your tests”. I’ll continue to share some of my personal highlights with you.

Replace multiple steps with a higher-level step

If a test executes multiple tasks in sequence that form a higher-level action, often the language and the concepts used in the test explain the mechanics of test execution rather than the purpose of the test, and in this case the entire block can often be replaced with a single higher-level concept.

Review

After reading “Discovery - Explore behaviour using examples” by Gáspár Nagy and Seb Rose, I picked up another book, which I bought a long time ago: “Fifty Quick Ideas to Improve Your Tests” by Gojko Adzic, David Evans, Tom Roden and Nikola Korac. Like with so many books, I find there’s often a “right” time for them. When I tried to read this book for the first time, I was totally not interested and soon stopped trying to read it. But ever since Julien Janvier asked me if I knew any good resources on how to write good acceptance test scenarios, I kept looking around for more valuable pointers, and so I revisited this book too. After all, one of the author’s of this book - Gojko Adzic - also wrote “Bridging the communication gap - Specification by example and agile acceptance testing”, which made a lasting impression on me. If I remember correctly, the latter doesn’t have too much practical advice on writing goods tests (or scenarios), and it was my hope that “Fifty quick ideas” would.

I’ve just finished reading “Discovery - Explore behaviour using examples” by Gáspár Nagy and Seb Rose. It’s the first in a series of books about BDD (Behavior-Driven Development). The next parts are yet to be written/published. Part of the reason to pick up this book was that I’d seen it on Twitter (that alone would not be a sufficient reason of course). The biggest reason was that after delivering a testing and aggregate design workshop, I noticed that my acceptance test skills aren’t what they should be. After several years of not working as a developer on a project for a client, I realized again that (a quote from the book):

Recently I read Ouarzy’s review of Jason Fried and David Heinemeier Hansson’s “Remote - Office Not Required”. I’d read their previous books, “Getting Real” and “Rework”. They’re all a joy to read. Short chapters, nice little cartoons. Just a lot of fun, and inspiring too. Not many authors make as much of an effort as they do to condense their message and reward the reader for taking the time to read an actual book. It’s insulting how much work some authors expect you to put in before they will reveal their secrets!

Legacy code

I’m happy that I’ve discovered the work of P.M. Jones recently. His and mine interests seem to align at several interesting points. Though I don’t personally enjoy “putting .308 holes in targets at 400 yards” (as quoted by Phil Sturgeon), I do care a great deal about package coupling (and cohesion for that matter) and I’m also lightly inflammable when it comes to the use of service locators. It also appears that Paul, just like myself and many others in this business, has felt the pain of working on a legacy PHP application, trying to add features to it, or change existing behavior. This is a particularly hard thing to do and because so many incompetent developers have been creating PHP applications since the dawn of PHP, chances are that a big part of the job of competent PHP developers nowadays consists of maintaining these dumpsites of include statements and superglobals.
