my blog. for you.

Let’s talk digital.

I’m an independent IT consultant and entrepreneur in the Internet and software business. I’m interested in design, enterprise applications, web apps and SaaS products. I design and develop business solutions and applications. I help companies in terms of software quality and knowledge transfer, e.g. with Angular and Spring Boot.

Kent Beck’s Novel Approach to Software Quality: test && commit || revert

In a Hanselminutes episode from December last year I heard preeminent programmer and agile advocate Kent Beck talk about his intriguing approach to creating working, high-quality code. In line with the steps this approach involves he calls it test && commit || revert. In lieu of the TDD circle of life (write test - test fails - write code - test passes - refactor - test fails ...) test && commit || revert has you commit each time when after a code ...

Dependency Management for Angular Unit Tests Using TestModuleMetadata

Since its inception it's always been one of the eminent design goals of Angular (and AngularJS before it) to make JavaScript applications easily testable and bake unit and E2E testing right into the development process. While the Angular team certainly has succeeded at this there's still the occasional snag you hit when writing unit or end-to-end tests. For the most part, the testing experience with Angular is terrific and testing JavaScript codebases has come a long way but of course there's always ...

Mockito 2 now available

Last week version 2.1.0 of the Mockito testing framework for Java has been released. For more information on this latest iteration check out this page. As the name suggests, Mockito allows you to mock object behaviour during unit tests. When writing unit tests you only want to test a particular unit's behaviour (hence the name). Depending on the programming language used such a unit might be a function, a procedure or - most commonly in today's object-oriented programming environments - a ...

Varying Degrees Of Software Quality And What To Do About It

When working on client projects I come across copious amounts of source code, which sometimes is very well-maintained, sometimes less so. The various code bases are as diverse as their owners and respective stakeholders: A few come with an inherent sense of quality, lots of unit tests serving as the specification for the product. They're typically delightful to maintain and extend. Some though at times leave the impression of having been cobbled together in a rather haphazard, impromptu manner in order to solve ...

Advice On Improving JavaScript Test Speed (by Shyp Engineering)

On their blog engineers of logistics service Shyp (defunct) talk about how they improved the turn-around times of their JavaScript test suite by an order of magnitude of 3 (i.e. 1000x), which is no small achievement. In a modern software development process continuous integration and continuous deployment play a vital role. These ensure that your software always is in an deliverable, tested state and ideally is deployed to production systems in a timely manner when a change has been made. This process ...
