OrcaSlicer/tests/cli/test_cli_project_missing_keys.sh

#!/usr/bin/env bash
# End-to-end check that the CLI loads a project's printer and process settings as the GUI does.
#
# The GUI takes every key a project does not list as changed from the project's current system preset:
# keys saved before an option existed, and keys holding an older system value. Keys the project lists
# in different_settings_to_system keep the project's value. A project is exported from the shipped
# Bambu Lab P1S presets; one printer key and one process key are removed, one printer key and one
# process key are changed without being listed, one key is changed and listed, and it is sliced again.
