From 17c36ed1248edf97a5f9fc72ff2c9073533c2816 Mon Sep 17 00:00:00 2001 From: rcourtman Date: Sun, 21 Dec 2025 20:31:24 +0000 Subject: [PATCH] Add more AI test coverage - findings_test.go: Add edge case tests for Acknowledge, Dismiss, SetUserNote, Suppress, Resolve, DeleteSuppressionRule, GetSummary, GetDismissedForContext (+20 tests) - intelligence_test.go: Add tests for calculateResourceHealth with anomalies/predictions/notes, FormatContext with various subsystems, generateHealthPrediction, GetSummary with patterns/learning (+17 tests) Coverage improvements: - internal/ai: 63.1% -> 64.4% - Overall AI module coverage now averages >80% --- internal/ai/findings_test.go | 187 ++++++++++++++++++++ internal/ai/intelligence_test.go | 294 +++++++++++++++++++++++++++++++ 2 files changed, 481
