We need to talk about testing

Or how programmers and testers can work together for a happy and fulfilling life.

Why don’t we just automate all the testing? Is test coverage a useful metric? What does it mean to “shift testing left”? When and where should we be testing? How much is enough testing?

CUPID—the back story

“If you had to offer some principles for modern software development, which would you choose?”

At a recent Extreme Tuesday Club (XTC) virtual meet-up, we were discussing whether the SOLID principles are outdated. A while ago I gave a tongue-in-cheek talk on the topic, so ahead of the meet-up one of the organisers asked what principles I would replace SOLID with since I disagreed with them. I have been thinking about this for some time and I proposed five of my own, which form the acronym CUPID.

The mystery of the missing date

My friend Gojko Adzic has been running a series of BDD quizzes illustrating different ways to approach some interesting BDD situations. I noticed on Twitter that Seb Rose, another BDDer (Cucumberer?), had gently taken issue with one of Gokjo’s solutions so I thought I’d take a look at them both. Before reading on I recommend reading Gojko’s solution and Seb’s response for context.

Accelerating Agile

A curious phenomenon

At the end of 2009 I left the world of agile delivery and consulting to join a small team in a trading firm. I was member number three. The team grew to five in the next few weeks. This team was the most insanely effective delivery machine I’ve ever been a part of. A handful of programmers sitting in amongst a handful of traders, producing state-of-the-art trading systems—with all the integration pain (back office, risk management, connecting to electronic exchanges) that involves—in weeks. Not months, weeks. This is, of course, impossible.

The rise and rise of JavaScript

I’ve been using JavaScript for a while now, but only really programming in anger with it during the last year. I’ve found it in turns frustrating and enlightening, ridiculous and brilliant. I have never felt so empowered by a language and its ecosystem, so I thought I’d take some time to write about why that is. I’m starting with a ramble through the history of JavaScript, or rather my undoubtedly inaccurate understanding of it, to provide some context for where and how I’ve been using it.
