# Headless editor logic tests

Runs the editor's real command / picking / camera / tool code (`editor.cpp`, `viewport.cpp`, `render.cpp`)
against **no-op raylib and Dear ImGui back-ends** (`stubs/` + `impl.cpp`), driving it with a scripted mouse.
No GPU or window needed, so it also works in CI.

    cmake -B build -DHPP_BUILD_EDITOR_LOGIC_TESTS=ON && cmake --build build --target test_editor_logic
    ctest --test-dir build -R editor_logic --output-on-failure

Linux + GNU ld/lld only (it links with `--unresolved-symbols=ignore-all` so UI-only code paths may stay
unresolved). The stubs mirror the raylib 5.5 / ImGui 1.91 signatures the editor uses; they are not a
re-implementation - they only exist so this code can be compiled and exercised without the real libraries.
