Running JUnit Tests Repeatedly Without Loops
Recently I came across a problem where I had to write tests for a method that calculates randomly distributed values within a certain range of possibilities 1. More precisely if you assume a signature that looks like interface RandomRangeValueCalculator { long calculateRangeValue( long center, long radius ); } a test might verify the following2: public [...]

WordPress Webhooked into GitHub
Code Affine is published using WordPress. Besides content provisioning there are technical tasks like site composition and software maintenance we have to take care of. Hence we were looking for a pragmatic but efficient way that allows us to develop locally, do versioning of changes, publish such changes automatically and last but not least run [...]

Working Efficiently with JUnit in Eclipse
Recently I was dragged into a discussion1 with some test infected2 fellows about how we use JUnit within the Eclipse IDE. Surprisingly the conversation brought up some ‘tips and tricks’ not everybody was aware of. This gave me the idea to write this post doing a sum up of our talk. Who knows – maybe [...]

JUnit Rules
The first time I stumbled over a JUnit @Rule annotation I was a bit irritated of the concept. Having a public field in a test case seemed somewhat odd and so I was reluctant to use it regularly. But after a while I got used to that and it turned out that rules can ease [...]

Running HTTP/REST Integration Tests efficiently in Eclipse
Lately I had a chance to use the OSGi-JAX-RS-Connector library written by my dear fellow Holger Staudacher. The connector enables you to publish resources easily by registering @Path annotated types as OSGi services – which actually works quite nicely. While it is natural for me to write the service classes test driven using plain JUnit [...]

RAP: Adapt Your Style
I really like the new RAP default theme introduced with the RAP 1.5 Release (see New and Noteworthy). It looks much more sophisticated and refined thus making RAP applications look ‘desgned for the web’, rather than ‘ported to the web’ as before. However, while working on my last customer project, I was looking for a [...]

How do you test equals and hashCode?
Just recently I had to implement equals() and hashCode() for several classes. With the aid of your favourite IDE, generating these methods is a matter of seconds. Well, if there weren’t the missing tests. As I tend to be obsessive when it comes to tests, I also want to have tests for equals() and hashCode(). [...]

How do you import static in Eclipse?
Long story short, I just discovered that Ctrl+Shift+M (Source > Add Import) can not only be used to add missing imports. It can also help with static imports. Executed on a reference to a qualified member (read Class.member), the refactoring will add a static import for the defining class and remove the class-dot expression. For [...]

Eclipse Archive Utilities
A little while ago I started a side project to support working with (zip) archive files in the Eclipse IDE. Initially it was more meant to revive my plug-in development knowledge and play around with some technologies like Tycho or SWTBot. But in the end, I though it might be useful enough to share. The [...]
