let selections = vec![
    Selection::Field(Field::new(String::from("myField"))),
    Selection::FragmentSpread(FragmentSpread::new(String::from("myFragment"))),
];
let mut selection_set = SelectionSet::new();
selections
    .into_iter()
    .for_each(|s| selection_set.selection(s));

assert_eq!(
    selection_set.to_string(),
    indoc! {r#"
        {
          myField
          ...myFragment
        }
    "#}
