To fix this, we can use AdditionalAnswers.delegatesTo() method as follows:34when(foo.foo()).then(AdditionalAnswers.delegatesTo(new Foo() {35    public String foo() {36        return "foo";37    }38}));39The above code will work fine. However, we can do better. We can use the AdditionalAnswers.delegatesTo() method to delegate the method invocation to the actual object. This will help us to avoid writing the code to return the value. We can use the following code to get the same result:40when(foo.foo()).then(
