From ff2a8dc5b1cb60ba2cfc80a850f34cc378abbe5a Mon Sep 17 00:00:00 2001 From: Egor Kostan Date: Tue, 17 Mar 2026 19:32:41 -0700 Subject: [PATCH 01/38] [FEATURE] Implement Unit Tests for Gameplay Settings Resource and Initialization #485 Description: Implement the foundation of the gameplay settings test suite, focusing on the GameSettingsResource as the single source of truth and the initial menu setup. Why is this useful?: Ensures that difficulty clamping (0.5 to 2.0) and signal emissions work correctly before the UI layer is involved. Proposed Implementation: Create test_game_settings_resource.gd covering: GS-RES-01 to 07: Validate clamping, boundary values (0.5, 1.0, 2.0), and redundant emission stability. GS-READY-01 to 06: Confirm _ready() correctly syncs the slider and label to Globals.settings.difficulty and connects signals exactly once. --- scripts/gameplay_settings.gd | 8 +- test/gut/test_game_settings_resource.gd | 131 ++++++++++++++++++++ test/gut/test_game_settings_resource.gd.uid | 1 + 3 files changed, 138 insertions(+), 2 deletions(-) create mode 100644 test/gut/test_game_settings_resource.gd create mode 100644 test/gut/test_game_settings_resource.gd.uid diff --git a/scripts/gameplay_settings.gd b/scripts/gameplay_settings.gd index 871378de2..fa71622c8 100644 --- a/scripts/gameplay_settings.gd +++ b/scripts/gameplay_settings.gd @@ -27,7 +27,10 @@ func _ready() -> void: #
