CSS get last child of a class

Question

Is there any way to select the last class inside a parent ?

There is a fiddle here : https://jsfiddle.net/98oc4Ler/

I tried both :

#banner-message .test:last-of-type {
  background: red;
}
#banner-message .test:last-child {
  background: red;
}

But it doesn't work, is there any way to select last element with a class inside a parent ?
