STRUCT KUNIT(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

struct kunit — bestie, it literally represents a running instance of a test ✨

so like, it's the struct that holds the whole vibe of a test while it's actually running, iykyk.

🎀 SYNOPSIS 🎀

struct kunit {
    void *priv;
    struct kunit *parent;
    struct kunit_params params_array;
 };

like, that's the whole shape of it 💖 three little fields, one big job.

🦋 Members 🦋

  • priv — this one's yours, bestie 💅 it's for you to store arbitrary data in. the classic move is passing in data you created in the init function (peep struct kunit_suite for that one 🫶).
  • parent — a reference to the parent context, and it's of type struct kunit, so it's the same vibe one level up 💫 use it for storing shared resources, iconic.
  • params_array — for storing the parameter array. that's it, that's the whole job, no cap 🍓

🌸 Description 🌸

okay so listen 👑 this struct is where all the info about the current context your test is running under lives. most of that data is private — like, not for you, you gotta go through the public functions to touch it, respectfully 🙈

the exceptions (the ones you're actually allowed to play with) are priv, parent, and params_array ✨ and what they do is: store arbitrary data, access the parent context, and store the parameter array — respectively, in that exact order, slay 💅

so basically: if it's not one of those three, hands off, use the public API, periodt.
