unit testing - How do I mock a static method in final class -

i have code has static method within final class. trying mock method. have tried doing few things..

public final class class1{ public static void dosomething(){ } }

how can mock dosomething()? have tried..

class1 c1=powermockito.mock(class1.class) powermockito.mocksatic(class1.class); mockito.donothing().when(c1).dosomething();

this gives me error:

org.mockito.exceptions.misusing.unfinishedstubbingexception: unfinished stubbing detected here: -> @ com.cerner.devcenter.wag.texthandler.assessmentfactory_test.testgetgradereport_htmlassessment(assessmentfactory_test.java:63) e.g. thenreturn() may missing. examples of right stubbing: when(mock.isok()).thenreturn(true); when(mock.isok()).thenthrow(exception); dothrow(exception).when(mock).somevoidmethod(); hints: 1. missing thenreturn() 2. trying stub final method, naughty developer! @ org.powermock.api.mockito.internal.invocation.mockitomethodinvocationcontrol.performintercept(mockitomethodinvocationcontrol.java:260)

most used testing framework junit 4. if using need annotate test class with:

@runwith( powermockrunner.class ) @preparefortest( class1.class )

than

powermockito.mocksatic(class1.class); mockito.donothing().when(c1).dosomething(); mockito.when(class1.dosomething()).thenreturn(fakedvalue); // phone call of static method required mock powermockito.donothing().when(class1.class); class1.dosomething();
