From 68cea367b3c9152b260cfce6ade2baa8f021bde6 Mon Sep 17 00:00:00 2001 From: Aparna Pradhan Date: Sat, 24 Jan 2026 11:24:52 +0530 Subject: [PATCH 1/9] feat: Add OpsMate agent tests and Makefile for deployment testing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - test_hunter.py: 30 tests for Zombie Hunter (EBS cleanup) - test_watchman.py: 30 tests for Night Watchman (staging shutdown) - test_guard.py: 28 tests for Access Guard (IAM revocation) - Makefile.opsmate: Sequential container testing rig (no docker-compose) - Add normalize_email() for +suffix handling in Guard - Add create_initial_*_state() functions for each agent - Fix should_shutdown quiet_hours edge case - Fix execute_shutdown error handling All 380 tests pass (3 skipped -
