more disks than temps (break branch) (97% -> 100%)
Go map iteration order is non-deterministic, causing flaky test failures.
This fix ensures "Composite" sensor is always preferred over "Sensor 1"
by checking them in separate loops rather than relying on iteration order.

cleanup, and mixed old/recent entries. Coverage improved from 71.4% to 100%.
Cover both branches: single alert template (isSingle=true with 1 alert)
and grouped alert template (isSingle=false or multiple alerts). Tests
verify subject format, HTML structure, and text body generation.
Coverage improved from 66.7% to 100%.
Cover all branches: nil/empty TimeThresholds, direct match, canonical key
matching (vm→guest, container→guest), "all" fallback, specific match
precedence, and global threshold fallback. Coverage improved from 85.7% to 100%.

conversion, endpoint ports, and labels cloning.
Add comprehensive error handling tests for two pure functions:
renderWebhookURL (8 new test cases):
- Empty/whitespace URL template validation
- Invalid template syntax (unclosed braces, undefined functions)
- Template producing empty URL
- Missing scheme or host in rendered URL
UpdateAllowedPrivateCIDRs (expanded from 8 to 29 cases):
- Invalid IP addresses (garbage, out of range, malformed)
- Invalid CIDR notation (prefix too large, negative, non-numeric)
- Malformed strings (double slash, invalid IP with valid prefix)
- Success cases for valid IPv4/IPv6 CIDRs and bare IPs
- Use public API AcknowledgeDockerHostCommand instead of private function
- Use strings.Contains instead of custom helper functions
- Add test case for empty hostID (skips validation, succeeds)
The error message referenced "Settings -> Docker -> Removed hosts" but
that UI path no longer exists. The correct path is now
"Settings -> Agents -> Removed Docker Hosts".

Add comprehensive tests for EnhancedEmailManager covering:
- Rate limiting (exceeds limit, resets after minute, concurrency, negative values)
- Provider username defaults (SendGrid, SparkPost, Resend, Postmark)
- TLS routing (TLS, StartTLS, plain connections)
- Retry logic (retries on failure, rate limit prevents retry)
- Connection error handling for sendTLS, sendStartTLS, sendPlain
This is the first test file for email_enhanced.go which previously had
0% coverage on sendTLS, sendStartTLS, and TestConnection functions.
Move guest threshold resolution and filter evaluation logic from
alerts.go to filter_evaluation.go for better code organization.
Extracted functions:
- evaluateFilterCondition
- evaluateVMCondition
- evaluateContainerCondition
- evaluateFilterStack
- getGuestThresholds
This reduces alerts.go by ~370 lines and isolates the rule evaluation
engine that determines which thresholds apply to guests.
Cover API validation functions that were previously untested:
- validateIPAddress: IPv4/IPv6 validation with edge cases
- validatePort: Port range validation (1-65535)
- defaultPortForNodeType: Proxmox node type to default port mapping
This function was superseded by HandleTestNode which is wired to the
router at /api/config/nodes/{id}/test. The old function was not
registered in the router and served no purpose.
Removes 121 lines of unused code.
The host-agent's isCPUChip function was missing rp1_adc (Raspberry Pi RP1 ADC),
which is already detected in the monitoring package. This sync ensures consistent
CPU temperature chip detection across both code paths.
Tests for annotateResolvedMetadata, resolveAppriseNotificationType,
normalizeQueueType, and resolvedTimeFromAlerts (44 test cases).
Coverage 38.0% → 39.0%.

trigger port fallback (refused, reset, no such host, timeout variants)
- shouldAttemptFallback: 13 cases for timeout/deadline/canceled patterns
used in storage polling fallback
- classifyDLQReason: 8 cases for dead letter queue reason classification
(max_retry_attempts vs permanent_failure)
- Edge cases: 3 cases for overlapping error patterns and partial matches
First test file for these error classification utilities used in retry
and fallback decision logic.
52 test cases covering:
- firstValueForKeys: 18 cases for multi-key lookup with priority ordering
- hasAnyKey: 15 cases for key existence checking
- discoveryConfigMap: 19 cases for nested config extraction with camelCase/snake_case support
Tests verify edge cases including nil maps, empty key slices, type assertion failures,
and priority ordering for field name variants used in configuration parsing.
Add 97 test cases for four utility functions in monitor.go:
- stringValue (30 cases): Type-to-string conversion for various Go types
including string, int types, float types, json.Number, fmt.Stringer

handling, string parsing, and json.Number support
- parseInterfaceStat (15 cases): Interface stat map parsing for network
interface statistics
- extractGuestOSInfo (18 cases): QEMU guest agent OS info extraction
with fallback logic for various Linux distros, Windows, FreeBSD
Coverage for these functions: 0% → 100%
Package coverage: 37.5% → 38.5%
Added comprehensive tests for 6 previously untested pure utility functions:
- sortContent: sorts comma-separated storage content values
- formatSeconds: converts total seconds to HH:MM:SS format
- dedupeStringsPreserveOrder: deduplicates strings while preserving order
- sanitizeGuestAddressStrings: validates and filters IP addresses
- copyFloatPointer: creates independent copy of float64 pointer
- clampInterval: clamps time.Duration to specified bounds
Tests cover edge cases including empty inputs, boundary conditions,
special values (DHCP, loopback addresses), and various separators.
Coverage increased from 36.8% to 37.5%.
Coverage for sessionHash, CreateSession, ValidateSession,
ValidateAndExtendSession, DeleteSession, persistence, and cleanup.
21 test cases covering session lifecycle, expiration handling,
and disk persistence. Coverage 25.0% → 25.3%.
Tests for detectProxy, isConnectionSecure, getCookieSettings, and
generateSessionToken functions. Covers proxy detection for various
headers including X-Forwarded-For, CF-Ray, Forwarded (RFC 7239),
and secure connection detection via TLS and proxy headers.
32 test cases covering makeNodeSnapshotKey and makeGuestSnapshotKey
utility functions used for diagnostic memory snapshot storage. Tests
cover simple inputs, edge cases (empty strings, negative VMIDs),
special characters, and key uniqueness verification. Also includes
struct field tests for NodeMemoryRaw and VMMemoryRaw.
First test file for diagnostic_snapshots.go. Coverage 36.7% → 36.8%.
The backup status indicator feature was incomplete - it added the UI
component but never populated VM/Container LastBackup from actual
backup data. Now SyncGuestBackupTimes() is called after storage
backups and PBS backups are polled, matching each guest's VMID to
its most recent backup timestamp.
Fixes#786
24 test cases covering transaction lifecycle: staging, commit, rollback, and cleanup.
Tests include atomic commit behavior, backup/restore on failure, directory creation,
permission handling, and idempotent cleanup.
First test file for import_transaction.go. Coverage 42.4% → 42.7%.
22 test cases covering CRUD operations (Get, GetAll, Set, Delete,
ReplaceAll), persistence (Load, save with atomic write, directory
creation), legacy ID migration (GetWithLegacyMigration for clustered
and standalone formats), round-trip verification, and concurrency.
First test file for guest_metadata.go, complementing the similar
docker_metadata_test.go added in previous run.
When multiple cluster nodes register sensor-proxy, each registration
was overwriting the previous node's control token on the shared
PVEInstance. This caused "Proxy token not recognized" errors on all
but the last-registered node.
Changes:
- Add TemperatureProxyControlToken field to ClusterEndpoint struct
- Store control tokens per-endpoint for cluster registrations
- Check both instance-level and endpoint-level tokens when validating
