ASSERT_TRUE(9)

💖 ASSERT_TRUE 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is ASSERT_TRUE(9), and she's lowkey one of the most straightforward little icons in the whole kselftest harness. no cap, this one's a snack 🍓

---

🌸 NAME 🌸

ASSERT_TRUE —

and that's it. that's the whole description. the manpage said "ASSERT_TRUE -" and then just stopped. not me staring at an empty NAME field 😭 she's mysterious, she's minimal, she's giving main character energy with zero backstory 💅

---

✨ SYNOPSIS ✨

ASSERT_TRUE (seen );

---

🎀 ARGUMENTS 🎀

• seen — the measured value, bestie. that's the thing you're putting on trial here 👀

---

🦋 DESCRIPTION 🦋

okay so the whole vibe, literally the entire vibe, is this:

ASSERT_TRUE(measured): measured != 0

that's it. that's the flex. you hand her a value and she goes "is this thing not zero??" and if your measured value IS zero, she does not let it slide 🙈 she's the literal truth-checker of the test harness, the vibe check in function form, and honestly? she ate 💅

ily, go write your tests 🫶💜
