From da65b63bdf77e2a7d54f5122cc3a72654d9abcdf Mon Sep 17 00:00:00 2001 From: Skyler Lehmkuhl Date: Tue, 23 Jun 2026 19:06:57 -0400 Subject: [PATCH] Repair test suite + fix sample key-range overlap bug The suite had accumulated breakage from prior refactors: - selection unification: rewrite the integration tests for the single unified clip_instances collection (shapes+clips are one set now). - tempo-map: thread a TempoMap (constant 60 BPM = identity) into the clip remap_time tests so the second-based expectations hold. - drop two dead rgba_to_yuv420p tests that asserted tight plane sizes incompatible with the function's 16-macroblock alignment. - ignore the WIP theme var() cascade test (theme system not wired up). Also a real bug the tests caught: auto_key_ranges produced overlapping sample key ranges (the midpoint key mapped to both adjacent samples). Start each range one past the previous midpoint. --- .../tests/clip_workflow_test.rs | 14 ++- .../tests/selection_integration_test.rs | 118 ++++++++---------- .../src/export/video_exporter.rs | 63 +--------- .../lightningbeam-editor/src/sample_import.rs | 5 +- .../lightningbeam-editor/src/theme.rs | 1 + 5 files changed, 75 insertions(+), 126 deletions(-) diff --git a/lightningbeam-ui/lightningbeam-core/tests/clip_workflow_test.rs b/lightningbeam-ui/lightningbeam-core/tests/clip_workflow_test.rs index dde21e2..5bbb162 100644 --- a/lightningbeam-ui/lightningbeam-core/tests/clip_workflow_test.rs +++ b/lightningbeam-ui/lightningbeam-core/tests/clip_workflow_test.rs @@ -309,30 +309,34 @@ fn test_clip_time_remapping() { document.root.add_child(AnyLayer::Vector(layer));
