Release Notes

mock-server/mockserver-monorepo (org.mock-server:mockserver-netty-no-dependencies)

v6.0.0

Added

Protocol & transport

• gRPC protocol mocking without a grpc-java dependency: upload a Protobuf descriptor and mock unary, client-streaming, server-streaming, and bidirectional-streaming RPCs; GrpcStreamResponse supports multi-frame streaming responses
• GraphQL body matching: whitespace-normalised query comparison, operationName matching, and variablesSchema JSON Schema validation for variables
• binary request/response mocking via BinaryRequestDefinition and BinaryResponse for non-HTTP protocols
• DNS mocking with dnsEnabled/dnsPort configuration and support for A, AAAA, CNAME, MX, SRV, TXT, and PTR record types
• IPv6 CONNECT proxy support including correctly bracketed IPv6 address handling in the CONNECT tunnel

Request matching

• probabilistic expectation matching: set a percentage field (0–100) on an expectation so only a fraction of matching requests are served by it, enabling fault-injection scenarios (fixes #​2122)
• HTTP method factory methods on HttpRequest: HttpRequest.get(path), .post(path), .put(path), .delete(path), .patch(path), .head(path), .options(path) for more concise expectation definitions (fixes #​1509)

Responses & actions

• multi-response expectations: define an httpResponses list with a responseMode of SEQUENTIAL (cycle repeatedly through the list in order) or RANDOM (pick at random) to serve different responses on successive matched requests
• multi-action expectations: compose response, forward, and callback actions in a single expectation with a primary action and post-action callbacks
• stateful scenarios with atomic state transitions: gate expectations behind named states and advance through them by setting newScenarioState on the expectation, making it straightforward to model multi-step protocols
• CRUD simulation via PUT /mockserver/crud: supply a data model and MockServer auto-generates a fully stateful REST API (list, create, read, update, delete) backed by an in-memory store
• FileBody response body type that loads content from a file path at response time, useful for large or binary payloads (fixes #​2163)
• in-memory file store: upload files via PUT /mockserver/files/store, retrieve via PUT /mockserver/files/retrieve, list via PUT /mockserver/files/list, and delete via PUT /mockserver/files/delete; stored files can be referenced by FileBody (fixes #​1652)
• respondBeforeBody flag on the request matcher to dispatch the configured response (and optionally close the connection) before MockServer reads the request body, useful for reproducing client behaviour when a server responds and closes mid-upload (fixes #​1831)

Delays & timing

• response delays with statistical distributions (uniform, Gaussian, log-normal) for realistic latency simulation (fixes #​1688)
• global response delay via mockserver.globalResponseDelayMillis configuration property to add a baseline delay to every response
• connection timeout emulation via mockserver.connectionDelayMillis configuration property: a configurable delay before protocol detection fires, so slow-connect scenarios can be tested without a real network (fixes #​1604)
• chunked dribble delay via ConnectionOptions.withChunkSize() / withChunkDelay() to drip-feed any response body in configurable-size chunks at a configurable rate

Response templates

• template helper functions: JWT generation, string manipulation, JSON path extraction, date arithmetic, and math operations available inside JavaScript, Velocity, and Mustache templates

Record & replay

• HAR 1.2 export: pass format=HAR to the retrieve API to get a standard HAR file of all recorded requests and responses (fixes #​2175)
• automatic persistence of recorded expectations: persistRecordedExpectations and persistedRecordedExpectationsPath configuration properties save recorded traffic to disk so it survives restarts (fixes #​2175)

Debugging & diagnostics

• per-expectation match count tracking: each expectation now exposes an invocation counter so tests can assert exactly how many times an endpoint was hit
• closest-match tracking: when a request does not match any expectation, MockServer identifies the expectation with the most fields satisfied and surfaces it via the API and dashboard
• debugMismatch() client method and PUT /mockserver/debugMismatch endpoint to programmatically retrieve the closest-match analysis for the last unmatched request
• match failure hints: actionable suggestions attached to EXPECTATION_NOT_MATCHED log events to guide correction of common mistakes
• "Why didn't this match?" debug dialog in the dashboard: click any unmatched request to see a field-by-field comparison against the closest expectation with per-field pass/fail indicators
• expectation ID included in EXPECTATION_NOT_MATCHED log messages to make it easier to correlate log output with the intended expectation (fixes #​1937)

Logging

• compact log format: set mockserver.compactLogFormat=true to emit single-line JSON log entries instead of multi-line formatted output (fixes #​1510)
• per-category log level overrides via mockserver.logLevelOverrides so individual event types can have different log levels (fixes #​1694)
• correlation ID retrieval: retrieveLogsByCorrelationId() client method and a correlationId chip in the dashboard for tracing a single request across all related log events
• retrieveLogEntries() client method returning typed LogEntry objects with optional time-range filtering; pass LOG_ENTRIES as the format to the retrieve API for programmatic access
• custom log event listener via a Consumer<LogEntry> callback registered with the Configuration object, enabling integration with external observability tools (fixes #​1960)

Proxy & forwarding configuration

• mockserver.forwardDefaultHostHeader configuration property: set a specific Host header value to send on all forwarded requests, overriding the original client Host header (fixes #​1782)
• mockserver.proxyRemoteHost and mockserver.proxyRemotePort configuration properties to route all proxy traffic through an upstream proxy (fixes #​1753)
• request forwarding timings captured per forwarded request: both connect time and total round-trip time are available in the log and dashboard (fixes #​1574)

OpenAPI

• OpenAPI callback support: MockServer reads callbacks entries in an OpenAPI specification and automatically creates AfterAction webhook expectations (fixes #​1483)

TLS & security

• BouncyCastle FIPS provider support for environments that require FIPS 140-2 compliant cryptography (fixes #​1769)
• support for custom TLS protocols TLSv1.2 and TLSv1.3
• better error messages when MockServerClient fails due to TLS or networking errors

Client & test integration

• @MockServerTest now applies mockserver.* prefixed properties to the per-instance MockServer Configuration object, enabling declarative configuration of initializationClass, logLevel, maxExpectations, and other settings directly in the annotation (fixes #​1554)
• Jackson StreamReadConstraints maximum string length raised to 100 MB to handle large JSON bodies without StreamConstraintsException (fixes #​1754)

Build & deployment

• Maven plugin initializationJson now accepts glob patterns to load multiple expectation files from a directory (fixes #​2231)
• mockserver/mockserver:graaljs Docker image tag that bundles the GraalJS engine JARs, enabling native ECMAScript 2022 support in response templates without Nashorn
• Docker HEALTHCHECK instruction added to all official images so container orchestrators can determine readiness without an external probe
• Helm chart podLabels value to attach arbitrary labels to MockServer pods, useful for service-mesh injection and internal routing rules (fixes #​1884)

Changed

• BREAKING: removed implicit reliance on internal java-certificate-classes (thanks to @​Arkinator)
• BREAKING: the classifier=shaded form of mockserver-client-java, mockserver-netty, mockserver-junit-jupiter, mockserver-junit-rule, and mockserver-spring-test-listener is no longer published. Use the corresponding *-no-dependencies artifactId instead (e.g. depend on mockserver-netty-no-dependencies rather than mockserver-netty with <classifier>shaded</classifier>). The *-no-dependencies variants are now proper Maven modules and are the supported way to consume a shaded MockServer jar.

Fixed

Proxy & forwarding

• proxy forwarding failures now return 502 Bad Gateway instead of 404 Not Found, making it clearer to clients that the upstream could not be reached (fixes #​1519)
• Host header updated to match the forwarding target to prevent 421 Misdirected Request errors from strict servers (fixes #​1897)
• request/response bodies with Content-Encoding are now re-compressed correctly when forwarding, preventing garbled bodies on the upstream (fixes #​1668)
• Transfer-Encoding header preserved on forwarded responses; spurious Content-Length header no longer added when Transfer-Encoding is present (fixes #​1733)

Request & response handling

• cookie values starting with ! were corrupted in forwarded responses (fixes #​1875)
• duplicate query parameter values are now preserved instead of being deduplicated (fixes #​1866)
• binary response bodies (e.g. application/octet-stream; charset=utf-8) were corrupted because a charset parameter in Content-Type caused the body to be treated as a string; now correctly treated as binary (fixes #​1910)
• JSON body serialization preserved numeric precision — 0.00 was incorrectly serialized as 0.0 (fixes #​1740)

OpenAPI

• ByteArraySchema (string format byte) properties were omitted from generated OpenAPI examples (fixes #​1788)
• $ref inside OpenAPI example values was not resolved, leading to raw $ref strings in generated responses (fixes #​1474)
• allOf/anyOf/oneOf composed schemas now generate merged example responses (fixes #​1852)
• OAS 3.0 boolean exclusiveMinimum/exclusiveMaximum now correctly translated to JSON Schema Draft-07 numeric format (fixes #​1896)
• OpenAPI 3.1 types array field now correctly preserved during schema serialization (fixes #​1940)

XML

• XSD schemas with xs:include or xs:import using relative paths now resolve correctly (fixes #​2118)

JUnit & Spring integration

• @MockServerTest field injection now works in @Nested JUnit 5 test classes (fixes #​1979)
• double server start when @MockServerSettings (carrying @ExtendWith) is combined with explicit MockServerExtension registration is now prevented (fixes #​1977)
• clientCertificateChain, localAddress, and remoteAddress fields on HttpRequest were serialized but not deserialized — both directions now work (fixes #​1973)
• MockServerClient parameter injection now works with @TestInstance(PER_CLASS) where the test instance is created before @BeforeAll (fixes #​1621)
• ClassNotFoundException for callback classes when running in a Spring Boot uber JAR (fixes #​1571)

Dashboard & WebSocket

• dashboard WebSocket returned 404 when MockServer was running behind a reverse proxy with a path prefix (fixes #​1693)
• HTTP/2 CONNECT proxy no longer hangs when the client advertises h2 via ALPN (fixes #​1933)
• WebSocket upgrade over HTTP/2 is now rejected cleanly instead of hanging the dashboard (fixes #​1803)

Concurrency & thread safety

• Times.remainingTimes() made thread-safe with AtomicInteger to prevent race conditions under concurrent load (fixes #​1834)
• XmlStringMatcher made thread-safe by creating a new DiffBuilder per match instead of sharing one (fixes #​1796)
• Disruptor ring buffer is drained before verify() to prevent false-positive or false-negative results under high throughput (fixes #​1757)
• expired TTL expectations are now filtered from the event bus and event bus subscribers are cleared after publish to prevent stale matches (fixes #​1847, #​1874)

TLS & mTLS

• mTLS (data-plane) enforcement moved from transport layer to application layer, fixing scenarios where client certificate validation was applied to non-mTLS connections (fixes #​1766)

Docker & deployment

• Docker image and standalone executable JAR produced no log output because the shaded server JAR did not include an SLF4J logging provider (fixes #​2097)
• *-no-dependencies shaded artifacts leaked their un-shaded source module (and its transitive dependencies) onto consumers' classpaths; these artifacts are now truly dependency-free
• netty-tcnative native libraries no longer bundled in the shaded JAR, preventing native library conflicts (fixes #​1778)
• Helm chart sub-chart deployments generated conflicting Kubernetes resource names when chart name was omitted (fixes #​1752)

Glob & file initialization

• glob brace expansion in initializationJson path failed to find the starting directory in some environments (fixes #​1715)
• WebSocket channel leak when the CircularHashMap evicted the oldest callback client (fixes #​1543)
• verify failure message incorrectly said "was not found" even when matching requests existed; message now accurately describes the mismatch (fixes #​1789)
