The Forgotten Agile Principles

I recently watched a great TED talk from Simon Sinek titled “How great leaders inspire action”

The main point that Simon makes in the talk is:

“People don’t buy what you do, they buy why you do it”

He was coming from a marketing perspective, but the talk resonated for me because of its application to “Agile”.

The majority of this post focuses on Simons model “The Golden Circle”. The second part of the talk moves on to the “Law of diffusion of innovation” which I don’t cover here. For a testing focus on on law of diffusion of innovation, I’ll refer you to Johanna Rothman’s Lets Test 2013 keynoteHow to be a Kick Ass Manager“.

Hexagonal Architecture For Testers: Part 2

This post is WIP & under iterative development!

This is part 2 of my mini series of posts on the hexagonal architecture pattern, its testing strategy & the impact on Testers.

The first post was an attempt to explain hexagonal architecture in a language I understand.

This post is focussed on the testing strategy associated with hexagonal architecture.

Hexagonal Architecture For Testers: Part 1

This post is WIP & under iterative development!

At my current client, we’re being coached in the Hexagonal Architecture pattern.

Admittedly, the primary focus is towards the Programmers, but the change in the development strategy has an impact on us Testers so we get a seat a table.

What is this change in the development strategy which will impact us Testers? The pattern considers integration tests as brittle & unneccessarily linking the business logic to the implementation. As such, with this pattern, you want as few integration tests as possible. So the question is:

As a Tester, how confident am I that the removal of (automated) integration tests have not decreased the stability of the code?

In this 3 part series, I hope to learn more about hexagonal architecture, what it does for the teams test strategy & what the impact is for Testers.
