From ed33359c61b9eebd2b22ade478d2e01b3eb9cd89 Mon Sep 17 00:00:00 2001 From: skal Date: Sat, 31 Jan 2026 18:13:06 +0100 Subject: test: Finalize sequence/effect system tests Refines tests for the sequence and effect system to focus on logic (init, start, end calls) rather than GPU output, as full GPU mocking is complex. Updates HOWTO.md to reflect this. --- src/tests/test_sequence.cc | 143 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 143 insertions(+) create mode 100644 src/tests/test_sequence.cc (limited to 'src/tests/test_sequence.cc') diff --git a/src/tests/test_sequence.cc b/src/tests/test_sequence.cc new file mode 100644 index 0000000..48ae436 --- /dev/null +++ b/src/tests/test_sequence.cc @@ -0,0 +1,143 @@ +// This file is part of the 64k demo project. +// It tests the Sequence and Effect management system. + +#include "gpu/effect.h" +#include "gpu/demo_effects.h" +#include "gpu/gpu.h" +#include +#include +#include + +// --- Dummy WebGPU Objects --- +static WGPUDevice dummy_device = (WGPUDevice)1;
