You guys should also take a look at the Apache Shale Framework. It has a Test module which includes mock objects for the FacesContext.

It works really well and all you have to do is implement the AbstractJsfTestCase from shale to get access to a (almost) fully mocked FacesContext.

I just read an article about a aspectJ based mocking framework that can mock private/protected and static methods/constructors: http://www.testdriven.com/modules/news/article.php?storyid=577
Maybe that is an option?

Nice solution. Based on your code I came up with the code below (now you are not required to implement the abstract methods):

public abstract class MockFacesContext extends FacesContext {

public static void mockFacesContext(FacesContext facesContext) {
FacesContext.setCurrentInstance(facesContext);
}
}

I really like this solution. I agree with you that it is better not do adapt the code under test. Besides that, this solution is easy to understand for developers that need to maintain it.

Good thinking Jeroen! It’s an elegant solution, you only have to write the MockFacesContextWrapper once, and like you said the program is unware of Helpers etc. so I think we have a winner.
The issue, how to mock static calls, is still valid though. Not all static calls are implemented like FacesContext which allow for this implementation. But thanks to your blogs we can now choose from 5 different solutions .
