Testing

Host tests — no cross-compile, no LVGL/SDL2 — run with:

make test
python3 tests/test_nebulascreen_release.py

make test builds and runs these targets (each a tests/test_*.cpp with the small framework in tests/minitest.h):

Target	Covers
test-nebulascreen-paths	Device paths, legacy (GuppyScreen-era) config mapping, nebulaos_ui_api check
test-config-theme-parse-safety	Config::init() / ThemeConfig::init() fall back to defaults on an unreadable or broken file, and the power-cut-safe save
test-subscription-baseline-ordering	Moonraker subscription baseline ordering in State
test-plr-status	Power-loss recovery panel states and commands
test-nebulaos-display	Brightness levels and display status
test-nebulaos-network	Static IP logic
test-nebulaos-macros	Mapping of screen actions to NebulaOS macros
test-nebulaos-calibration-flow	Guided calibration screens
test-nebulaos-system	Power & System and Logs logic
test-nebulaos-settings	Connections, Wi-Fi and Updates logic
test-nebulaos-image	Settings → Updates → System image logic

tests/test_nebulascreen_release.py tests the release packager (scripts/nebulascreen_release.py).

For visual work, use the SDL simulator (Development and simulator). Hardware testing on a real printer is still the final check before a NebulaOS build ships.
