Events in spring v2

java

Last time I wrote about events in a spring based application I’ve introduced some basics on how events can be dispatched using spring infrastructure. In this post, I’m going to dig deeper into an order of handlers, exceptions and asynchronous events handlers.

On behavior verifications

best practices

When I’ve got some free time I try to add new features to springmock. Lately, after adding some new stuff I realized that double definition parsing class has more than one responsibility (class parsing, naming, definition creation, etc). So I’ve decided it’s time to refactor it and split responsibilities into dedicated classes. Once I did that and tests in the shared kernel started to pass I executed mvn verify just to be sure that everything was working and it wasn’t…​

That’s great and easy to understand if you are not using spock. The problem is that in spock there are better ways to mock stuff…​

Problem with random test data

java

Some time ago I noticed new library in our code base - Random Beans which as the name suggests is a tool developed to easily create random data and random objects for testing purposes. Unfortunately, we used it in the wrong way. Here’s how we backed up from the random test data to regain control over testing.
