Parameterized JUnit tests with JUnitParams


Parameterized unit tests are used to to test the same code under different conditions. Thanks to parameterized unit tests we can set up a test method that retrieves data from some data source. This data source can be a collection of test data objects, external file or maybe even a database. The general idea is to make it easy to ...

Run, JUnit! Run!!!


JUnit together with JavaScript and SVN are some of the technologies that programmers often start using without even reading a single blog post let alone a book.  Maybe this is a good thing since they look simple enough and understandable so we can use them right away without any manuals, but this also means that they are also underused.

JBoss Drools unit testing with junit-drools


Recently I’ve been working with a project heavily using JBoss Drools. I am not Drools expert – I am not also very convinced to this framework, or maybe only to particular use case in this project – and I found it quite difficult to write simple, maintainable unit tests for Drools based business rules. That’s how junit-drools was born – ...
