STRUCT KUNIT_FAIL_ASSERT(9)

💅 NAME 💅

Okay so welcome to the Kernel API Manual, bestie! Today's main character is struct kunit_fail_assert — and yes, it literally represents a plain fail expectation/assertion. It's giving "I'm the error message you didn't want but needed" energy. 🫶 No cap, it's a whole vibe.

---

🦋 SYNOPSIS 🦋

Here's the whole look, fr fr:

struct kunit_fail_assert {
    struct kunit_assert assert;
};

That's it. That's the struct. Simple, iconic, to the point. ✨

---

🌸 Members 🌸

• assert — the parent of this type. It's the OG, the one who raised it, the struct kunit_assert that holds everything together. Lowkey the backbone of the whole operation. 💖

---

💖 Description 💖

So what does this little icon actually do? It represents a simple KUNIT_FAIL / KUNIT_FAIL_AND_ABORT that always fails. Like, it's not even trying to pretend — it's a fail, periodt. 💀 If you're writing a test and you want to force a failure (maybe to test the test framework itself, iykyk), this is your girl. Just know that there's no conditional logic here; it's a straight-up "nope" in struct form. It's literally the definition of "not me failing on purpose" but make it kernel code. 😭🔥

🔥 SEE ALSO 🔥

You already know we gotta shout out the whole squad. Go check out the kernel file ./include/kunit/assert.h and these legendary structs and enums, fr fr:

• enum kunit_assert_type(9)
• struct kunit_loc(9)
• struct kunit_assert(9)
• struct kunit_unary_assert(9)
• struct kunit_ptr_not_err_assert(9)
• struct kunit_binary_assert_text(9)
• struct kunit_binary_assert(9)
• struct kunit_binary_ptr_assert(9)
• struct kunit_binary_str_assert(9)
• struct kunit_mem_assert(9)

They're all part of the same iconic friend group, and you should lowkey give them a read. The way that they all live in ./include/kunit/assert.h together is so cute. 📚✨💅

That's the whole page! Catch you later, bestie 💖 This masterpiece was brought to you by the kernel file ./include/kunit and the very real date October 2026. Stay slay, keep your structs close, and remember: a fail is just a slay waiting to happen. 🎀🦋💜
