### Question:
Tuple5MapperImpl extends AbstractTupleMapper<T, Tuple5<T0, T1, T2, T3, T4>> implements TupleMapper<T, Tuple5<T0, T1, T2, T3, T4>> { public Function<T, T1> get1() { return getAndCast(1); } Tuple5MapperImpl(
            Function<T, T0> m0,
            Function<T, T1> m1,
            Function<T, T2> m2,
            Function<T, T3> m3,
            Function<T, T4> m4); @Override Tuple5<T0, T1, T2, T3, T4> apply(T t); Function<T, T0> get0(); Function<T, T1> get1(); Function<T, T2> get2(); Function<T, T3> get3(); Function<T, T4> get4();  }### Answer:
@Test void get1() { assertEquals(m1, instance.get1()); }
