The Big Announcement, This Year, at Devoxx 2011!

Stephan Janssen started the developer conference with his traditional "Welcome and Announcements" and this year announced Devoxx France, the new and only Devoxx conference outside of Belgium. It will take place in Paris, April 18 to 20, 2012. The Paris Java user group is organizing the 3 day conference. The conference is designed after Devoxx with Tools in Action, Labs, BOFs and Quickies and with one university day and 2 conference days. The model works well since Stephan turns down attendees every year. The content will be 75% in French and 25% in English. Call for papers opened today. Oracle will be a sponsor at the event!

Unit Testing for Java EE tech article on OTN

A new article, titled “Unit Testing for Java EE,” by Java Champion Adam Bien, is up on otn/java’s front page. Bien points out that too many developers believe that testing Java EE applications is too hard, inconvenient, or complex, something that has not been true since the advent of Java EE 5 more than five years ago.

Bien explains: “There is nothing special about unit testing Java EE 6 applications. You only have to add the JUnit library into your pom.xml file (see Listing 5) and put your classes into the src/test/java directory. All JUnit tests will be executed automatically during the standard Maven lifecycle: mvn clean install.”

He goes on to make use of “Mockito” an easy-to-use, open source mocking library. Bien writes:

“Mockito is able to create ‘smart proxies’ (a.k.a. mocks) from classes or interfaces. These proxies do not come with any behavior, but they are still perfectly usable. You can invoke methods, but will get the default values, or null, back. The behavior of the mocks can be recorded after their creation with when(mock.getAnswer()).then(42) syntax.

Mockito is perfectly suitable for ‘simulating’ any inconvenient classes, resources, or services. You can start with Mockito just by knowing a single class org.mockito.Mockito. The when-then ‘domain specific language’ is composed of static methods from the Mockito class. The org.mockito.Mockito class is well documented. In fact, the whole documentation set was generated from the JavaDoc markup in the org.mockito.Mockito class.”
