Use Mockito/Power Mockito to mock a private method

Question

I need to use Mockito/Power Mockito to mock a private method. I am using testng, and most of the examples I see online are for mocking private method using PowerMock+Junit - Mocked private method with PowerMock, but underlying method still gets called

Can anyone please point me to examples where I can use Power Mockito+testng. I have been looking for a while, but no luck so far.
