FIXTURE_VARIANT_ADD(9)

🌸 FIXTURE_VARIANT_ADD(9) — NAME 🌸

okay so welcome to the FIXTURE_VARIANT_ADD(9) page from the Kernel API Manual, bestie 💖 this one is called once per fixture variant to setup and register the data, and it's lowkey iconic.

---

✨ SYNOPSIS ✨

       FIXTURE_VARIANT_ADD (fixture_name , variant_name );

---

🎀 ARGUMENTS 🎀

• fixture_name — fixture name, periodt.
• variant_name — name of the parameter set, iykyk.

---

🦋 DESCRIPTION 🦋

okay so here's the whole vibe:

           FIXTURE_VARIANT_ADD(fixture_name, variant_name) {
             .property1 = val1,
             ...
           };

this defines a variant of the test fixture, and that variant gets provided to FIXTURE_SETUP and TEST_F as variant. Tests of each fixture will be run once for each variant — yes, every single one, no cap 🫶
