Mocking FacesContext

Question

I am trying to add some unit tests to a JSF application. This application didnt rely heavily on any best practices, so many service methods use the FacesContext to

I give you an example to mock FacesConext without using PowerMockito. The idea is to extend a simple class from Facescontext, and change the current instance using protected static method setCurrentInstance:

import javax.faces.context.FacesContext;
import javax.servlet.ServletContext;

import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import com.sun.faces.config.InitFacesContext;

public class DummyTest {

    @Mock
    private FacesContext context;

    @Before
    public void before(){
        MockitoAnnotations.initMocks(this);
        ServletContext sc = mock(ServletContext.class);
        new FakeContext(sc);
        assertEquals(context, FacesContext.getCurrentInstance());
    }

    @Test
    public void dummy(){

    }

    private class FakeContext extends InitFacesContext{

        public FakeContext(ServletContext sc) {
            super(sc);
            setCurrentInstance(context);
        }

    }

}
