From 79e0b05b1954c8dae034822f99568c5ee4e192b2 Mon Sep 17 00:00:00 2001 From: kvvasuu Date: Fri, 31 Jul 2026 22:25:06 +0200 Subject: [PATCH] test: add smoke coverage for every effect component Mounts each effect with minimal props inside a real EffectComposer and checks it doesn't crash and disposes correctly; a coverage test fails CI if a new file under src/effects isn't added to the manifest or the exclusion list, so this can't silently go stale as effects are added. --- src/tests/effects.smoke.test.tsx | 234 +++++++++++++++++++++++++++++++ 1 file changed, 234 insertions(+) create mode 100644 src/tests/effects.smoke.test.tsx diff --git a/src/tests/effects.smoke.test.tsx b/src/tests/effects.smoke.test.tsx new file mode 100644 index 00000000..f2b38d1f --- /dev/null +++ b/src/tests/effects.smoke.test.tsx @@ -0,0 +1,234 @@ +// Generic smoke coverage for every effect component: mounts inside a real +// EffectComposer with the minimum props each one actually requires, confirms +// mounting/unmounting doesn't throw, and that dispose() gets called exactly +// once per instance on unmount (for both -based effects, via our +// useDispose hook, and wrapEffect-based ones, via r3f's own auto-dispose). +// +// This catches constructor/prop-application/dispose-time crashes — it does +// NOT verify visual/shader correctness.
