This post has originally been published on the codecentric blog. A few days ago I wrote about a library called Testcontainers. It helps you to run software that your application depends on in a test context by providing an API to start docker containers. Testcontainers comes with a few pre-configured database- and selenium-containers, but most …
I’ve been working in my current project for a while now and while it has its problems I mostly enjoy my envolvement in it. The project is based on Spring Boot and consists of a bunch of web-applications, both for endusers, internal personnel and operations staff. The team takes testing seriously, we have different code-quality …
This post has originally been published on the codecentric blog. It was translated to english and slightly edited for this blog. A month back the JUnit team published the offical version of JUnit 5. There’s plenty of resources for high level overviews and if you want to catch up I can recommend this (german) article …
After three years without any new JUnit version, a few weeks back on September 10th a new version of JUnit has been published: JUnit 5! While there were only minor upgrades to the popular testing library over the last couple of years, this was a big release that the JUnit team had been working on …

A lot has happened in the meantime: Letsencrypt has evolved quite a bit and I’ve been using other means of automating provisioning tasks (namely Puppet and Ansible) as well. For …

I looked up when I first heard about this event and I traced it back to end of July: Another interesting event in #Nuremberg area this autumn: Softwareengineering-Camp in Erlangen https://t.co/tZSjiSAnpC — reinhard//codes (@reinhard_codes) …
A few days ago VirtualJUG featured a very interesting talk on the upcoming new version of JUnit, namely JUnit 5. Nicolai Parlog did a great job in explaining the new features and architecture of the new version – if you haven’t seen it yet, go ahead and watch it. This weekend I’ve been getting my …
When writing Java, I’m a big fan of Lombok, a library that helps reduce boilerplate code through code-generation. I’ve written about it in the past, if you’re not familiar with it, checkout my previous posts here and here. Recently I’ve been confronted with the problem of providing defaults for generated Builder-classes generated by the @Builder …
There’s no shortage of options for Java developers when dealing with HTTP connections client-side. Java itself brings facilities to work with HTTP, but they are very low level and inconvenient as is Apache’s HttpClient.
