From ab3d1163cce17f58b85eecba8dbc56641ec5228e Mon Sep 17 00:00:00 2001 From: "Dr. Armando Vaquera (proyectoauraorg)" Date: Wed, 20 May 2026 13:35:04 -0600 Subject: [PATCH 1/4] test(readFileTool): add comprehensive test coverage for readFileTool - Add 44 new tests covering edge cases and untested code paths - Tests for legacy path handling, handlePartial errors, getStartLine fallback - Tests for getLineSnippet when lines exceed file length - Tests for batch approval flow and media provider integration - Tests for file path normalization and edge cases - Total test count: 77 (was 33, added 44)

console.warn spy in afterEach to prevent leakage Addresses CodeRabbit nitpick: several tests installed vi.spyOn(console, "warn") without restoring it, leaking the mock across tests. Added a scoped afterEach that restores console.warn only (via vi.isMockFunction guard) so the suite's module-level mocks are left intact. 75 tests pass.
