test:

}
tests := []struct {
name string
args args
want Int
}{
{
name: "equal zero",

},
{
name: "equal one",
args: args{
i: "1",

},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
if got := NewIntFromString(tt.args.i, tt.args.valid); !reflect.DeepEqual(got, tt.want) {
t.Errorf("NewIntFromString() = %v, want %v", got, tt.want)

}
}

I use this like:
id:= zero.NewIntFromString(c.GetQuery("id"))
where c is a gin.Context (could do similar with http.GetForm)
