### Question:
Functions { @SuppressWarnings("unchecked") @NonNull public static <T> Function<T, List<T>> itemAsList() { return (Function) ITEM_AS_LIST_FUNCTION; } private  Functions(); @NonNull static Function<F, T> staticFunction(@NonNull final T object); @NonNull static Function<F, T> supplierAsFunction(
      @NonNull final Supplier<? extends T> supplier); @NonNull static Function<T, T> identityFunction(); @NonNull @SuppressWarnings({"unchecked", "UnusedParameters"}) static FItem<F, F> functionFrom(@Nullable Class<F> from); @NonNull @SuppressWarnings({"unchecked", "UnusedParameters"}) static FList<F, List<F>, List<F>> functionFromListOf(
      @Nullable final Class<F> from); @SuppressWarnings("unchecked") @NonNull static Function<Throwable, Result<T>> failedResult(); @SuppressWarnings("unchecked") @NonNull static Function<Result<T>, List<T>> resultAsList(); @SuppressWarnings("unchecked") @NonNull static Function<T, List<T>> itemAsList(); @SuppressWarnings("unchecked") @NonNull static Function<Result<List<T>>, List<T>> resultListAsList();  }### Answer:
@Test public void shouldReturnFunctionReturningListWithValue() { assertThat(Functions.<Integer>itemAsList().apply(VALUE), contains(VALUE)); }
