KUNIT_EXPEC...ARNING_COUNT(9)

📦 version 7.3.1, in nixpkgs unstable

✨ KUNIT_EXPECT_SUPPRESSED_WARNING_COUNT ✨

okay so real talk, this is a page from the Kernel API Manual (manual name: KUNIT_EXPEC...ARNING_COUNT(9), yes the title is literally truncated in the middle of the word, the kernel manpage generator said "that's a you problem" 💀). Anyway. Bestie. Sit down. Let's talk about counting warnings that got suppressed. 🎀

💖 NAME 💖

KUNIT_EXPECT_SUPPRESSED_WARNING_COUNT — this one sets an expectation that the suppressed warning count equals @expected. That's the whole vibe check. 🦋

🌸 SYNOPSIS 🌸

KUNIT_EXPECT_SUPPRESSED_WARNING_COUNT (test , expected );

🧚 ARGUMENTS 🧚

  • test — the test context object. the main character of the whole operation honestly 👑
  • expected — an expression that evaluates to the expected warning count. like, how many warnings do you expect to have been suppressed. do the math, bestie 🍓

🔥 DESCRIPTION 🔥

so what this does is set an expectation that the number of suppressed WARN*() calls equals expected. simple as that, no cap.

and here's the tea: it's semantically equivalent to KUNIT_EXPECT_EQ(test, KUNIT_SUPPRESSED_WARNING_COUNT, expected). literally the same thing, just a glow-up with a cuter name. 💅

if you want the whole lore, see KUNIT_EXPECT_EQ for more information. iykyk. ✨

🌈 SEE ALSO 🌈

background reading, in the kernel file ./include/kunit/test.h, and the extended universe of friends:

ngl this whole list is giving "required reading for the group project" but everyone in it actually pulls their weight 🫶

and that's the page, bestie!! this lil icon came from the kernel source dir ./include/kunit, dated October 2026 — go off, kernel docs, we love a timestamped slay 💜🌸💅
