Powermock - Creating mock object for final class and mock it for a static method

[vishnukumar gr]

Hi,

I'm new to PowerMock. I'm trying to unit test a class that has a code as GWT.getHostPageBaseURL(). Here, GWT is a final class and getHostPageBaseURL() is a static method. So, for testing final class, I use PowerMock to create mock object for this code, like the below

GWT mock = PowerMock.createMock(GWT.class);
EasyMock.expect(GWTMock.getHostPageBaseURL()).andReturn(new String("http://localhost/"));
PowerMock.replay(GWTMock);

I followed wiki http://code.google.com/p/powermock/wiki/MockStatic to create a mock object for the final class. However, I got an error message as below

Caused an ERROR

Please, tell me how to fix this problem?

Thank you
