### Question:
Tuple3OfNullablesMapperImpl extends AbstractTupleMapper<T, Tuple3OfNullables<T0, T1, T2>> implements TupleMapper<T, Tuple3OfNullables<T0, T1, T2>> { public Function<T, T2> get2() { return getAndCast(2); } Tuple3OfNullablesMapperImpl(
            Function<T, T0> m0,
            Function<T, T1> m1,
            Function<T, T2> m2); @Override Tuple3OfNullables<T0, T1, T2> apply(T t); Function<T, T0> get0(); Function<T, T1> get1(); Function<T, T2> get2();  }### Answer:
@Test void get2() { assertEquals(m2, instance.get2()); }
