It’s been a while since I wrote code these days. Back in late April however I found myself in a Coding Dojo at the Düsseldorf Softwerkskammer meet-up working on the Mars Rover Kata. I have a story to share from that meeting. However, since I tried to reproduce the code we ended up with that night, and I decided to give JUnit5 (and Java8) a go for that, I ended up with a struggle.
Back in the days with JUnit4 I used the ParameterizedRunner quite often to use data-driven tests. I never remembered the signature of the @Parameters function, though. The Mars Rover Kata also includes some behavior that I wanted to run through a data-driven test, but how do you do that in JUnit5? I couldn’t find good answers for that on the Internet, so I decided to put my solution up here – probably for lots of critique.
Please note that I used JUnit 5.0.0-SNAPSHOT which is a later version than the alpha, but probably not the final one.Continue reading Data-driven tests in Junit5.0.0-SNAPSHOT
