From 7ca838be47aec7e641737c551a9578fce3d1c683 Mon Sep 17 00:00:00 2001 From: jeda Date: Tue, 3 Mar 2026 15:17:52 +0000 Subject: [PATCH] feat(bd-2ar): Add blessed TUI tests for app.ts main TUI class MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive test coverage for FabricTuiApp including: - Constructor with default and custom options - createTuiApp factory function - All key bindings (q, C-c, ?, tab, S-tab, r, C-k, enter, H, D, escape) - start/stop lifecycle methods - addEvent and render methods - View mode switching (default, heatmap, DAG) - Help overlay toggle - Command palette toggle - Tab navigation - Worker detail view - Edge cases (empty store, multiple starts, events before start) All components are mocked using class syntax for proper constructor mocking. Process.exit is mocked to prevent test termination. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Worker --- src/tui/app.test.ts | 782 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 782 insertions(+) create mode 100644 src/tui/app.test.ts diff --git a/src/tui/app.test.ts b/src/tui/app.test.ts new file mode 100644 index 0000000..84ed7a6 --- /dev/null +++ b/src/tui/app.test.ts @@ -0,0 +1,782 @@ +/** + * Tests for FabricTuiApp Main TUI Class + * + * Tests initialization, key handling, and component coordination. + */ + +import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
