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 …
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. I’ve been using some more high-level implementations in the past, Spring’s RestTemplate is often a good fit, the same goes for …
I’ve written about Project Lombok’s @Builder annotation before (see here and here). We’ve started using it in our project some time ago in favour of the code generation library PojoBuilder. One thing has bugged me though during that time: Lombok’s @Builder annotation won’t generate code for inherited fields. It turns out, there is a solution to …
You don’t need to be particularly interested in technology or privacy to know that a lot of companies are following you around as you browse the web. There’s a huge market for personal information which is mostly used to serve targeted ads. Lots of information is available online that goes into great detail on how …
Some time ago I’ve written about Project Lombok’s @Builder annotation. When used, it will automatically create a builder for your Java POJOs. Lately, I’ve had some trouble using it on generic classes. Initially I thought that Lombok might need some improvements in this area, but it turned out that I was just using it wrong. …
A few weeks back I wrote about my endeavour to reinstall a private server that I own using the configuration management tool Chef. One of the things that I wanted to revisit was the way I managed a test environment. I had basically manually set up a virtual machine and that I could use as …
After reinstalling Owncloud using Chef (see this post) I had to spend some time figuring out how to import existing calendar data into an Owncloud calendar. Initially I wanted to subscribe to a remote calendar (bank holiday data) in the Owncloud web interface, but I didn’t find a way to do this. Instead, I created …
