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…​

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.
