This is the second part of my writeup of the session I did at XPDays Benelux and XP 2016 in Edinburgh called “Bourne Again” on bootstrapping a unit testing framework in the Bourne Again Shell (bash). This series of posts walk you through the steps I took in 75 minutes of programming.

Over the years, we have done our share of UI and front end development. Long long time ago with SmallTalk, Visual Basic and Delphi, building web applications with server side rendering and React, and being involved in Angular projects at several clients. Recently we have been building front ends based on Vue.js. In a series of blog posts, we are going to share how we approach (hexagonal) architecture, test driven development, and incremental design in the front end.

Happy new year! We are restarting open enrollment courses this year. The first one up is our test driven Java course. This will take place in Utrecht, Netherlands in March 19 and 20 in 2020.

Do you have pending tests left over from yesterday? Better delete them before they grow stale.

Red-Green-Refactor is broken, because the psychological reward happens at green. When you get that reward, you feel the task has been completed, and are inclined to stop. Therefore refactoring is a lot rarer than it should be.

I was planning to use my keys left for something different today, but found myself in an associative storm of tweets, possible conference sessions to be proposed and some situated software I’ve been working on for a few years, intermittently.

For a production application I’m using PUX, a purescript wrapper around React. In the way we use it for WeReview we are experiencing performance and usability issues, beyond the slow rendering.

Read MoreYesterday I thought I pushed out another iteration of our attempt at making the QWAN website more accessible. Turns out I didn’t. While adjusting details, reading CSS and accessibility documentation and blogposts, I missed the fact that the shiny assets pipeline I added does not actually build on github.

The QWAN site currently is not accessible for blind users. If you were to use a screen reader, the page might just as well be blank. A blind colleague mentioned to us a while ago that they could not read the home page at all. I have just started improving it.

In a previous post, we elaborated on why and how we apply Hexagonal Architecture in front end applications.
Read More
Front ends tend to start out simple, often as ‘just’ a form or a grid showing data that comes from a backend. It looks like ‘just’ a visual layer on top of backend APIs. When a front end evolves and grows, it inevitably becomes more complex. We then need to take a good hard look at the UX/UI and overall architecture.

Hexagonal Architecture, also known as Ports and Adapters, is getting quite a bit of (well-deserved!) attention recently, especially in the Domain Driven Design community. Hexagonal Architecture is not a new thing: it was originally thought up by Alistair Cockburn (of Agile Manifesto fame) in the 90ies.

Continuous delivery is valuable, but where do you start? At the start of a greenfield development you have no software, and if you had any software, you would not know how to put it into production.
Read More
Starting new product development with the question ‘What can we leave out?’ may seem paradoxical. We do this to start a conversation between customers and developers. As we go we develop a shared language, so that value can be delivered early and often. This is called Dimensional Planning.

A couple of days ago, Jamie Dobson and Simon Wardley did a back to back presentation on Cargo Cults and mapping DevOps and serverless. Great athmosphere in the virtual room. My son made a cameo apperance near the end. One can’t grow strategists young enough.
