How to mock private static final field

Question

I have class which I need test:

class MyClass {
    private final static MyOtherClass myOtherClass = OtherClassFactory.get();
    public void doSomething() {}
}

How to mock myOtherClass in unit test?

Answer 1

You can use the Deencapsulation.setField method from the JMockit mocking library; it supports setting of final fields as well (as long as the field is not initialized to a compile-time constant, which is not the case here).
