There are still some software companies that release their software to the users only every month. In this article we construct a model for business value realisation and demonstrate based on it what such companies actually loose. We focus on this business value realisation and ignore for a moment other…

When we are developing software, most of the time we are not typing. Reading and thinking take the largest share. Nevertheless it makes sense to optimise the typing part. Because we want quick feedback if we have an idea. This is especially true in the red-green-refactor cycle of TDD. So…

The FizzBuzz task: Write a program that prints the numbers from 1 to 100. But for multiples of 3 print “Fizz” instead of the number and for the multiples of 5 print “Buzz“. For numbers which are multiples of both 3 and 5 print “FizzBuzz”. Let’s solve this example test-driven…

The article Getting Started with Cypress e2e Testing in Angular describes how to setup Cypress for an Angular project. In this post we go a step further and cover how to use Cypress for automated e2e testing in your CI/CD workflow. Jenkins is used as automation server and I assume…

Automating e2e tests is an important aspect of software engineering. It helps shipping updates often while quickly being able to see that the software is most likely still working properly. Unfortunately such tests are usually time consuming in creation and execution. We have a look at how cypress.io can be used…

We have a look at the 23 Gang of Four design patterns for object oriented software design. While a lot of blog posts describe them using examples around concepts like Animal, Car or Pizza, we explain each of them by a practical example. It is certainly not wrong to learn…
