1. One of NPE solutions for mock

SomeClass someclass = mock(SomeClass.class,Mockito.RETURNS_DEEP_STUBS);

assertThrows(RunTimeException.class,
            ()->{
                 //logic code
            });

3. Mock/Test private method

@InjectMocks
PrivateInClass privateInClass;
ReflectionTestUtils.invokeMethod(privateInClass, "privateMethodName", param1, param2, ...);
