Although period scheduling can also be useful, the cron expressions give us much more control over the invocation of the scheduled tasks. That is […] Read more

I think that the integration testing of Spring Data Repositories is an important and often neglected topic. That is why I decided to turn my recent blog post about it into a screencast which answers to the following question: How can we write tests for our repositories because after all, they are just interfaces?
