From 447478785bf2b2af2e8a59c2ae9971b3fa27281f Mon Sep 17 00:00:00 2001 From: rcourtman Date: Mon, 1 Dec 2025 13:34:23 +0000 Subject: [PATCH] test: Add unit tests for filter_evaluation.go functions Tests for alert filter evaluation logic: - evaluateVMCondition: metric/text/raw conditions for VMs - evaluateContainerCondition: same for containers - evaluateFilterStack: AND/OR logic with multiple conditions - evaluateFilterCondition: type dispatch 74 test cases covering: - All metric types (cpu, memory, disk, diskread, diskwrite, network) - All comparison operators (>, <, >=, <=, =, ==) - Text search fields (name, node, vmid) with case insensitivity - Raw text search across multiple fields - Value type conversions (int to float64) - Edge cases (zero, empty, invalid types) Coverage improved from 46.8% to 48.9%. --- internal/alerts/filter_evaluation_test.go | 1099 +++++++++++++++++++++ 1 file changed, 1099 insertions(+) create mode 100644 internal/alerts/filter_evaluation_test.go diff
