PowerMockito + Junit + Ant

[Seema Kekre]

I am new to Powermockito. I have a Junit4 setup with Ant1.7.1. I am mocking a final class using mockito 1.8.5

    @PrepareForTest({FinalDB.class})
    private static SomeClass getMockSomeClass() {
        FinalDB bf = mock(FinalDB .class); 

When I run this test using Eclipse, it runs fine. When I run the test using my ant build I get the following error. From this error it looks like it can find Powermockito and mockito in its classpath and there is just one mockito jar in the lib (claspath).

My eclipse and Ant are pointing to the same junit. I dont think this is a Junit issue, but a mockito issue but I cannot figure out how to start figuring out the issue.
<taskdef name="junit" classname="org.apache.tools.ant.taskdefs.optional.junit.JUnitTask"> <classpath> <pathelement location="${l3extlibdir}/junit-4.8.2.jar"/> </classpath> </taskdef>

Why does it work with Eclipse and not with Ant? How can I figure out the order in which the Classloaders are loaded?

Thanks in advance.
Seema.

Was able to figure it out. For some reason, using mock for final classes in static causes a java.lang.ExceptionInInitializerError. When I changed this to a class method it still throws this Exception but my tests pass. Will post on Powermockito forum to understand this better.

using mockito we cannt mock the final classes but if you are using powermockito then it can be done..Just put the powermockit jar in the classpath and remove mockito jar
