PowerMock: stub methods from parent class

Question

I'm using PowerMock and I'd like to know how to keep all behavior of the child class, but stub super calls that may be overriden by the child.

Say I have this class:

public class A {     public String someMethod() {         return "I don't want to see this value";     } } 

and a sub class:

public class B extends A {     @Override     public String someMethod() {         return super.someMethod() + ", but I want to see this one";     } } 

How do I stub the call to super.someMethod()?

I've tried

@Test public void test() {     B spy = PowerMockito.spy(new B());     PowerMockito.doReturn("value").when((A)spy).someMethod();      assertEquals("value, but I want to see this one", spi.someMethod()); } 

Answer 1

You can try suppressing the methods from the Parent class,

PowerMockito.suppress(methodsDeclaredIn(A.class)); 

Here's an article on Stubbing, suppressing and replacing with PowerMock that might be of some use.
