KUNIT_EXPECT_STRNEQ(9)

📦 version 7.3.1, in nixpkgs unstable

💅 KUNIT_EXPECT_STRNEQ(9) — like, the whole page, bestie

okay so you're reading the Kernel API Manual ✨ (that's the manual name, yes, we're fancy now) and honestly? good choice. this one is a cutie. let's get into it 🎀

🌸 NAME

KUNIT_EXPECT_STRNEQ — expects that strings @left and @right are not equal. that's it, that's the whole vibe. they are simply not the same string, and we are expecting that. 💅

✨ SYNOPSIS

KUNIT_EXPECT_STRNEQ (test , left , right );

look at that. three little arguments. so clean. so iconic. 🫶

🧚 ARGUMENTS

  • test — the test context object. like, the main character of the test. everything goes through it 💖
  • left — an arbitrary expression that evaluates to a null terminated string. yes, null terminated. don't forget the null terminator bestie, that's the whole point 🔥
  • right — an arbitrary expression that evaluates to a null terminated string. same deal. also null terminated. they're matching that way, even if the strings themselves are SO not matching 😌

🦋 DESCRIPTION

so what this actually does: it sets an expectation that the values left and right evaluate to are not equal. that's the whole thing. that's the assignment.

and ngl, it's semantically equivalent to this:

KUNIT_EXPECT_TRUE(test, strcmp((left), (right)))

like, literally the exact same energy. strcmp comes back nonzero, that means "different", that means we pass. slay. 🌈

if you want more info on how that expectation machinery works, go read KUNIT_EXPECT_TRUE — it's the parent vibe, this one's just a glow-up 💜
