FIXTURE_TEARDOWN(9)

💅 FIXTURE_TEARDOWN ✨

okay so bestie, welcome to FIXTURE_TEARDOWN(9) from the Kernel API Manual — this is the one that gives your fixture its lil goodbye kiss 🫶 it's the cleanup era, and honestly? iconic.

---

🌸 NAME 🌸

FIXTURE_TEARDOWN — no cap, that's literally the whole name entry, the og page leaves the description blank so we're matching energy 💀 (it's giving mysterious main character, we respect it)

---

🎀 SYNOPSIS 🎀

FIXTURE_TEARDOWN (fixture_name );

---

🦋 ARGUMENTS 🦋

• fixture_name — the name of your fixture, bestie. that's it. that's the argument 💖

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — *_metadata* gets included in there so that EXPECT_*, ASSERT_*, etc. all work correctly. like, they need that metadata to function, it's their whole support system fr fr.

FIXTURE_TEARDOWN(fixture_name) { implementation }

so what this macro does: it populates the required "teardown" function for a fixture. the way that works is — an instance of the datatype you defined with FIXTURE_DATA gets exposed as self, so your implementation can clean up after itself 🧹✨. it's giving responsible queen behaviour.

and good news for the early-exit girlies: a bare return; statement is totally allowed if you wanna bounce out early 🔥

ngl, this is the cleanup function — keep it chill, keep it tidy, and remember self is your fixture instance, so treat her right 💅
