Test::...erarchy(3pm)

💖 NAME 💖

Test::Run::Class::Hierarchy — bestie, this lil module hands you a list of super-classes, all lined up in topological order. Yes, the fancy word. Yes, it slays. ✨

---

🌸 SYNOPSIS 🌸

okay so this is literally how you use it, no cap:

use Test::Run::Class::Hierarchy;

my $base_classes = hierarchy_of("MyClass::Sub::Sub::Sub");

my $base_classes_rev = rev_hierarchy_of("MyClass::Sub::Sub::Sub");

see? two whole functions. that's the vibe. 💅

---

🦋 DESCRIPTION 🦋

It returns a list of classes in the current namespace. that's it, that's the whole personality. 🎀

⚠️ but bestie, listen — it caches the results. so don't come for it later being like "why didn't it update", because it told you. it's giving "I remember everything" main character energy and honestly? respect.

---

👑 EXPORTS 👑

✨ my [@list] = hierarchy_of($class) ✨

Returns a list of the classes in the hierarchy of the class, going from bottom to top. so like, you start at the little baby subclass and climb your way up to the ancestors. 🧚 ascending, as one does.

✨ my [@list] = rev_hierarchy_of($class) ✨

Returns the classes from top to bottom. same list, flipped. the reverse. the remix. 🔥
