I Don't Measure Code Coverage

I believe that test coverage is an unhelpful measure. I have two main reasons behind this belief: Firstly, test coverage often gives false positives and false negatives; and secondly, too many badly written tests will slow a project down (that is, higher coverage can mean lower habitability).

Book Review: Version Control With Git

If you need detailed information about GIT, then this is the deal (short of reading the source code I guess). Every aspect of the tool is explained (sometimes in excruciating detail) and the authors go to a great length to provide tips and gotchas on commands (especially when you might easily shoot yourself in the foot).

The DevOps Team Myth

Should there really be such a thing as a “DevOps Engineer”? Probably not, but we’re far too late to stop it, and trying to stop it seems a bit of a waste of energy to me. Eventually “DevOps Engineer” will come to mean something more specific, but for now we’re just going to have to read a few more lines on CVs.

DevOps: Tools Vs Culture

DevOps is a marriage between tools and culture. If you are just using the tools that you heard about at a recent DevOps Days and not also embracing the culture (or at least working towards it) then you're not really "doing DevOps".

The Ship Show: The Epistemology of DevOps

How do we know, we know what DevOps is? For episode 46, we sit down with Praxisflow’s Kevin Behr (whom you might recognize as one of the authors of the Phoenix Project) and Jabe Bloom to talk about these and other heady questions, including: what can we learn from the Agile community?

The Basics of Test-Driven Development

The objectives of Test Driven Development and unit testing are generally misunderstood. The problem is the word ‘test’, it is much less about testing and much more about specification of requirements, showing your working – as in maths, and the impact it has on design.

Trunk Supporting Practices

Environment config, isn’t the same as “infrastructure as code”. This is the stuff that’s potentially live-tunable in an application stack that subsumes feature toggles, but goes further – application specific things not limited to rectangles of web-pages appearing or disappearing.

Test Attribute #9 – Deterministic

I keep hammering on trust and how it’s crucial that we trust our tests. If a test is deterministic, it raises the level of our trust. If it isn’t, we may question its result, which will be followed by questioning other tests as well.

Organization Antipattern: Dual Value Streams

The goal of Continuous Delivery is to optimise cycle time in order to increase product revenues, and cycle time is measured as the average lead time of the value stream from code checkin to production release. This was memorably summarised by Mary and Tom Poppendieck as the Poppendieck Question.

Encapsulating Value Streams and the Object Oriented Enterprise

The value stream associated with software development typically goes something like this: analysis, design, build, test, and deploy. That’s pretty much everything you need to develop a working tested increment of the product… and therefore what defines the basic requirements for a Scrum team.

Feature Toggles are one of the worst kinds of Technical Debt

Feature flags or config flags aka feature toggles aka flippers are an important part of Devops practices like dark launching (releasing features immediately and incrementally), A/B testing, and branching in code or branching by abstraction.

Create Your Own Private Docker Registry

Shortly after you start building docker containers you will realize that you need some place to publish your images. You could push to the central docker registry. However, the central registry is public. Not a great idea if you are working on a private project.

Test Attribute #8 – Truthiness

Tests are about trust. We expect them to be reliable. Reliable tests tell us everything is ok when they pass, and that something is wrong when they fail. Tests can give false positive (fail when they shouldn’t) or false negative (pass when they shouldn’t) results.

Spring Boot Microservices With Docker (part one)

A microservice is similiar to the “S” in the SOLID design principals. It is a service that has only one single responsibility. These small services are then composed together to make a cohesive system. The small services are independently deployable and distributable. In the new “cloud” world, elasticity is the game.
