Maven pom Checkstyle configuration with Eclipse

In a previous post on Eclipse plugins, two excellent plugins were mentioned which can automatically set up your Eclipse project to use the same Checkstyle configuration that is configured in your pom file. However, the only problem with both of these plugins is that they will only be able to find your Checkstyle configuration if […]

JSF, Iterating with tomahawk radio buttons, t:datalist, a4j:repeat

The standard JSF radio buttons h:selectOneRadio render a load of old school html (i.e. they use table tags to do layout, (all a bit 1996)). e.g. JSF h:selectOneRadio tag Code for #{radioOptions} Note: I’m using jboss seam in the example above, but you could easily remove the seam annotations and define the bean in using […]

Mocking

Mocking Statics and IllegalStateException: no last call on a mock available

If you use PowerMock to mock a static object e.g. and encounter the following error: Check that you have prepared the Class for test using the @PrepareForTest annotation. e.g. An excellent article discussing mocking statics by one of the PowerMock developers can be found here: http://blog.jayway.com/2009/05/17/mocking-static-methods-in-java-system-classes/ Note that you also need to @PrepareForTest any classes […]

Cobertura code coverage with Maven and PowerMock

If you use Powermock for unit testing with Maven and Cobertura for code coverage, you are likely to be affected by the following issue noted on the PowerMock issue tracker. If you did not have the maven-surefire-plugin forkmode configured to ‘pertest’, you would find that any tests annotated with @RunWith(PowerMockRunner.class) had zero percentage code coverage […]

Chain

Chaining EasyMock’s expectation return values

Recently I discovered quite a handy feature of EasyMock’s IExpectationSetters andReturn method.
