From 9e33ad645cf83f9fbb3ab39032b16303493ae561 Mon Sep 17 00:00:00 2001 From: Kelsi Date: Tue, 5 May 2026 14:49:05 -0700 Subject: [PATCH] test: add unit tests for WOB and WHM open format round-trips MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - WOB save/load round-trip: verifies groups, vertices, indices, portals, doodad placements with rotation and scale preservation - WOB toWMOModel conversion: verifies WOB→WMO geometry bridge works - WHM heightmap save/load: verifies 256-chunk terrain with per-vertex height data round-trips correctly through binary format - WHM invalid magic rejection: verifies corrupt files are rejected - WOB missing file rejection: verifies graceful failure - 29 new assertions across 5 test cases --- tests/CMakeLists.txt | 14 ++++ tests/test_open_formats.cpp | 162 ++++++++++++++++++++++++++++++++++++ 2 files changed, 176 insertions(+) create mode 100644 tests/test_open_formats.cpp diff --git a/tests/CMakeLists.txt b/tests/CMakeLists.txt index 3ddcc1ec..cd13c5fd 100644 --- a/tests/CMakeLists.txt +++ b/tests/CMakeLists.txt @@ -399,6 +399,20 @@ target_link_libraries(test_gm_commands PRIVATE catch2_main) add_test(NAME gm_commands COMMAND test_gm_commands) register_test_target(test_gm_commands) +# ── test_open_formats ──────────────────────────────────────── +add_executable(test_open_formats + test_open_formats.cpp + ${CMAKE_SOURCE_DIR}/src/pipeline/wowee_building.cpp + ${CMAKE_SOURCE_DIR}/src/pipeline/wowee_terrain_loader.cpp + ${CMAKE_SOURCE_DIR}/src/pipeline/wmo_loader.cpp + ${CMAKE_SOURCE_DIR}/src/core/logger.cpp +) +target_include_directories(test_open_formats PRIVATE ${TEST_INCLUDE_DIRS}) +target_include_directories(test_open_formats SYSTEM PRIVATE ${TEST_SYSTEM_INCLUDE_DIRS}) +target_link_libraries(test_open_formats PRIVATE catch2_main) +add_test(NAME open_formats COMMAND test_open_formats) +register_test_target(test_open_formats) + # ── ASAN / UBSan for test targets ──────────────────────────── if(WOWEE_ENABLE_ASAN AND NOT MSVC) foreach(_t IN LISTS ALL_TEST_TARGETS) diff --git a/tests/test_open_formats.cpp b/tests/test_open_formats.cpp new file mode 100644 index 00000000..6f4ef79f --- /dev/null +++ b/tests/test_open_formats.cpp @@ -0,0 +1,162 @@ +// Tests for Wowee open format round-trips (WOM, WOB, WHM/WOT) +#include +#include "pipeline/wowee_building.hpp" +#include "pipeline/wmo_loader.hpp" +#include "pipeline/wowee_terrain_loader.hpp" +#include "pipeline/adt_loader.hpp" +#include +#include +#include + +using namespace wowee::pipeline;
