Tests for Proxmox client authentication error handling:
- authHTTPError.Error: message formatting based on status code
(401/403 include status in message, others don't)
- shouldFallbackToForm: determines when to retry with form encoding
(triggers on 400/415, not on auth errors or server errors)
16 test cases covering all code paths.
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%.
Tests for LXC container config parsing functions:
- sanitizeRootFSDevice: rootfs device extraction
- collectIPsFromInterface: recursive IP extraction from various types
- parseContainerRawIPs: JSON IP parsing
- parseContainerConfigNetworks: network interface parsing with MAC
normalization, CIDR stripping, sorting

- mergeContainerNetworkInterface: interface merging by name/MAC
- convertContainerDiskInfo: Proxmox disk info conversion
- ensureContainerRootDiskEntry: root disk entry creation
91+ test cases covering edge cases, invalid data, and complex scenarios.
Coverage improved from 40.6% to 42.2%.
Tests for all 9 functions handling Docker host identification:
- uniqueNonEmptyStrings: dedupe with order preservation
- sanitizeDockerHostSuffix: string cleaning for IDs
- tokenHintFromRecord: redacted token hints
- dockerHostIDExists: ID existence check
- dockerHostSuffixCandidates: candidate suffix generation
- fallbackDockerHostID: hash-based ID generation
- findMatchingDockerHost: host matching by various criteria
- generateDockerHostIdentifier: unique ID generation with suffixes
- resolveDockerHostIdentifier: main resolver orchestration
86 test cases covering edge cases (nil, empty, whitespace), Unicode
handling, and complex matching scenarios.
Tests cover nil/empty inputs, basic field copying, time fields
(CreatedAt/UpdatedAt with nil and zero value handling), update status
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 added by ADA run #97 but commit was missed.
Covers: RaidZ types, log/cache/spare devices, nested mirrors,
ConvertToModelZFSPool, and struct field tests.
The VERSION variable was hardcoded to v4.32.0 instead of being empty,
which prevented the "fetch latest release" logic from running. When
VERSION is empty, REQUESTED_VERSION defaults to "latest" which triggers
proper release detection via GitHub API.

Tests for annotateResolvedMetadata, resolveAppriseNotificationType,
normalizeQueueType, and resolvedTimeFromAlerts (44 test cases).
Coverage 38.0% → 39.0%.
Add comprehensive tests for the cloneProfile and clonePhase utility
functions in pkg/discovery/discovery.go. Tests verify deep copying
behavior for all fields including subnets, metadata, warnings, extra
targets, and phases to ensure mutations don't affect original objects.
Add 56 test cases covering:
- isTransientError: 13 cases for context errors, retryable MonitorErrors,

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

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%.
Test coverage for error detection and retry logic:

- isAuthError: 12 test cases for authentication errors
Coverage 35.5% → 37.3%
The StackedMemoryBar component was using flex layout for segments,
but flex children grow by default regardless of percentage width.
Changed to absolute positioning (like MetricBar uses) so the width
percentages actually work as expected.

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%.
