From 3055bd2d8545ce7eaf082a53c4eb246b9a54abd6 Mon Sep 17 00:00:00 2001 From: Jason Woltje Date: Thu, 5 Feb 2026 16:08:55 -0600 Subject: [PATCH] fix(#337): Fix boolean logic bug in ReactFlowEditor (use || instead of ??) - Nullish coalescing (??) doesn't work with booleans as expected - When readOnly=false, ?? never evaluates right side (!selectedNode) - Changed to logical OR (||) for correct disabled state calculation - Added comprehensive tests verifying the fix: * readOnly=false with no selection: editing disabled * readOnly=false with selection: editing enabled * readOnly=true: editing always disabled - Removed unused eslint-disable directive Refs #337 Co-Authored-By: Claude Opus 4.5 --- .../mindmap/ReactFlowEditor.test.tsx | 270 ++++++++++++++++++ .../components/mindmap/ReactFlowEditor.tsx | 3 +- 2 files changed, 271 insertions(+), 2 deletions(-) create mode 100644 apps/web/src/components/mindmap/ReactFlowEditor.test.tsx diff --git a/apps/web/src/components/mindmap/ReactFlowEditor.test.tsx b/apps/web/src/components/mindmap/ReactFlowEditor.test.tsx new file mode 100644 index 0000000..c1c80b0 --- /dev/null +++ b/apps/web/src/components/mindmap/ReactFlowEditor.test.tsx @@ -0,0 +1,270 @@ +/** + * ReactFlowEditor Tests + * Tests for the boolean logic in handleDeleteSelected + * - When readOnly=false AND selectedNode=null, editing should be disabled + * - When readOnly=false AND selectedNode exists, editing should be enabled + * - When readOnly=true, editing should always be disabled + */ + +import { describe, it, expect, vi, beforeEach } from "vitest"; +import { render, screen, fireEvent } from "@testing-library/react"; +import { ReactFlowEditor } from "./ReactFlowEditor"; +import type { GraphData } from "./hooks/useGraphData"; + +// Mock ReactFlow since it requires DOM APIs not available in test environment +vi.mock("@xyflow/react", () => ({ + ReactFlow: ({ + nodes, + edges, + children, + onNodeClick, + onPaneClick, + }: { + nodes: unknown[]; + edges: unknown[]; + children: React.ReactNode; + onNodeClick?: (event: React.MouseEvent, node: { id: string }) => void; + onPaneClick?: () => void; + }): React.JSX.Element => ( +
