Move 29 MQTT test files from NATS.Server.Tests into a dedicated
NATS.Server.Mqtt.Tests project. Update namespaces, add
InternalsVisibleTo, and replace Task.Delay calls with
PollHelper.WaitUntilAsync for proper synchronization.
Move TLS, OCSP, WebSocket, Networking, and IO test files from
NATS.Server.Tests into a dedicated NATS.Server.Transport.Tests
project. Update namespaces, replace private GetFreePort/ReadUntilAsync
with shared TestUtilities helpers, extract TestCertHelper to
TestUtilities, and replace Task.Delay polling loops with
PollHelper.WaitUntilAsync/YieldForAsync for proper synchronization.
- git mv JetStreamApiFixture, JetStreamClusterFixture, LeafFixture,
Parity utilities, and TestData from NATS.Server.Tests to
NATS.Server.TestUtilities
- Update namespaces to NATS.Server.TestUtilities (and .Parity sub-ns)
- Make fixture classes public for cross-project access
- Add PollHelper to replace Task.Delay polling with SemaphoreSlim waits
- Refactor all fixture polling loops to use PollHelper
- Add 'using NATS.Server.TestUtilities;' to ~75 consuming test files
- Rename local fixture duplicates (MetaGroupTestFixture,
LeafProtocolTestFixture) to avoid shadowing shared fixtures
- Remove TestData entry from NATS.Server.Tests.csproj (moved to
TestUtilities)
Add shared test utility library with TestPortAllocator.GetFreePort() and
SocketTestHelper.ReadUntilAsync() to deduplicate helpers across test projects.
This is the foundation for splitting the monolithic test project into
feature-focused test projects.
Updated gaps 1.5-1.10, 2.4, 2.7-2.12, 3.1, 3.5, 3.8-3.13, 7.1-7.6,
and 8.3-8.8 with IMPLEMENTED status, implementation file references,
task/phase numbers, and test file names. All 93 sub-gaps across 15
sections are now marked as IMPLEMENTED. Updated test count to 6,920.
Added 1,006 new test entries from the 8-phase remaining gaps
implementation across JetStream, Auth, Routes, LeafNodes, Monitoring,
Events, Config, Gateway, WebSocket, and Internal test directories.
Updated all gap sections (3-15) with IMPLEMENTED status markers,
implementation file references, and test file names covering all
8 phases of the remaining gaps plan.

layer for account-scoped filtering and pagination that mirrors the Go
server's /connz ?acc= query-parameter behaviour. Ten new tests in
ConnzAccountFilterTests.cs cover FilterByAccount (match, no-match,
case-insensitive), ConnzFilterOptions.Parse (acc param, defaults,
offset/limit), and ApplyFilters (account filter, offset, limit,
no-filter pass-through).

and MessagesRead/MessagesWritten counters, and exposes IsConnected. Ten
NSubstitute-based unit tests cover all capability flags, delegation, and
telemetry (10/10 pass).
Add SupportsPooling/IsLegacyRoute properties to RouteConnection and
GetLegacyRoute/GetLegacyRoutes/HasLegacyRoutes to RouteManager. Update
GetRouteForAccount to fall back to legacy routes when no dedicated or
pool-capable route is available, matching Go route.go getRoutesExcludePool.
Add SetPermissions/PermsSynced/AllowedPublishSubjects/AllowedSubscribeSubjects/AccountName
to LeafConnection, and SendPermsAndAccountInfo/InitLeafNodeSmapAndSendSubs/GetPermSyncStatus
plus LeafPermSyncResult to LeafNodeManager. Add OnConnectionRegistered internal callback for
test synchronization. 10 new unit tests in LeafPermissionSyncTests.cs all passing.

tests in LeafTlsReloadTests covering change detection, no-op idempotency, path
tracking, counter semantics, and result payload.
Add NegotiatePoolSize static method and NegotiatedPoolSize property to
RouteConnection, and ConfiguredPoolSize / GetEffectivePoolSize to
RouteManager. Includes 14 tests covering negotiation semantics, backward
compatibility (zero means no pooling), default state, and deterministic
pool index computation.
Add RemoveRoute, RemoveAllRoutesExcept, RegisterRoute (internal), and
DetectClusterSplit to RouteManager with ClusterSplitResult record, plus
10 tests covering partition detection and route removal behavior.
Add _accountRoutes ConcurrentDictionary to RouteManager with full
CRUD API: RegisterAccountRoute, UnregisterAccountRoute,
GetDedicatedAccountRoute, HasDedicatedRoute,
GetAccountsWithDedicatedRoutes, and DedicatedRouteCount property.
Update GetRouteForAccount to check dedicated routes before falling
back to pool-based selection. Add 10 unit tests in AccountRouteTests.
Adds GatewayConnectionState enum, GatewayRegistration record with atomic
message counters, and a full registry API on GatewayManager: RegisterGateway,
UpdateState, GetRegistration, GetAllRegistrations, UnregisterGateway,
GetConnectedGatewayCount, IncrementMessagesSent, IncrementMessagesReceived.
Covers 11 new tests in GatewayRegistrationTests.cs (all passing).
Add ReplyMapCache to ReplyMapper.cs — an LRU cache with TTL expiration
for gateway reply subject mappings, avoiding repeated string parsing on
the hot path. Includes 10 unit tests covering LRU eviction, TTL expiry,
hit/miss counters, PurgeExpired, and Count.
Adds GatewayReconnectPolicy with exponential backoff and jitter, and
reconnect attempt tracking (GetReconnectAttempts, ResetReconnectAttempts,
ReconnectGatewayAsync) to GatewayManager. 10 new tests cover delay
calculation, cap behaviour, jitter, and per-gateway counter isolation.
Adds per-account subscription tracking to GatewayConnection via
AddAccountSubscription/RemoveAccountSubscription/GetAccountSubscriptions/
AccountSubscriptionCount, with corresponding SendAccountSubscriptions and
GetAccountSubscriptions helpers on GatewayManager. Covered by 10 new unit tests.
Adds LoggingChangeResult and ApplyLoggingChanges to ConfigReloader, deriving
an effective log level from Debug/Trace flags (Trace > Debug > Information) and
reporting flag-level and level-string changes for hot-reload notification.
Add ApplyJetStreamConfigChanges to ConfigReloader for detecting MaxMemoryStore,
MaxFileStore, and Domain changes during hot reload. Add Domain property to
JetStreamOptions. Port 10 unit tests covering all change permutations.
Adds ClusterConfigChangeResult and ApplyClusterConfigChanges to ConfigReloader,
comparing route/gateway/leaf URL sets between old and new NatsOptions and reporting
added/removed routes for connection reconciliation on hot reload.
Add PropagateAuthChanges to ConfigReloader that compares Users, Accounts,
and Authorization token between old and new NatsOptions, returning an
AuthChangeResult describing which auth fields changed for connection re-evaluation.
Add FlapperState class and per-client exponential backoff tracking to
MqttSessionStore. New TrackConnectDisconnect(string) overload returns
FlapperState with backoff level and expiry; IsFlapper, GetBackoffMs,
ClearFlapperState, and CheckAndClearStableClients give callers full
visibility and cleanup control. Legacy two-arg overload preserved for
backward compatibility. Ten unit tests cover counting, threshold,
exponential growth, 60s cap, window reset, and stable-client sweep.
