From ef075e74cfd9004a7f9d1da6f1f5f5ff715419b8 Mon Sep 17 00:00:00 2001 From: Gu1llaum-3 Date: Wed, 10 Sep 2025 08:15:46 +0200 Subject: [PATCH] test: add comprehensive test suite and fix failing tests - Fix history tests with proper test isolation using temp files - Fix CMD tests with proper string contains and simplified assertions - Add missing test utilities and helper functions - Improve test coverage across all packages - Remove flaky tests and replace with robust alternatives" --- cmd/add_test.go | 88 ++++++++++++++ cmd/edit_test.go | 70 ++++++++++++ cmd/root_test.go | 144
