MockServer is a mock HTTP server that enables easy mocking of any system you integrate with via HTTP or HTTPS (i.e. services, web sites, etc) with clients written in Java, JavaScript and Ruby. MockServer also includes a proxy that introspects all proxied traffic including encrypted SSL traffic and supports Port Forwarding, Web Proxying (i.e. HTTP proxy), HTTPS Tunneling Proxying (using HTTP CONNECT) and SOCKS Proxying (i.e. dynamic port forwarding).

Hello Mockserver community.

I would like to know if it is possible to build a Mockserver Expectation where a value of the HTTP Response can be dynamically created based on a value from the HTTP Request. I'm thinking something like capturing a regex match from the request and putting that captured value into the response.

My use case is that I want to match all requests to a particular route, but I want to capture the query parameters. I then want to be able to have these query parameters stored in an HTTP header in my response (in my specific case, the Location header).

Is this currently possible in Mockserver? I am using the API client right now. Thank you.

@ecbrodie it is possible to do what you need, the easiest way is to use an object callback: http://mock-server.com/mock_server/creating_expectations.html#button_response_method_or_closure_callback it is also possible using a class callback: http://mock-server.com/mock_server/creating_expectations.html#button_response_class_callback it is also possible using a velocity template: http://mock-server.com/mock_server/creating_expectations.html#button_javascript_velocity_templated_response and finally it is possible using a javascript template: http://mock-server.com/mock_server/creating_expectations.html#button_javascript_templated_response

Hello Mockserver community, I am new to MockServer and new to java. I have been trying to initialize expectations using the initializationClass configuration property 'java -Dmockserver.initializationClass="org.mockserver.server.initialize.ExpectationInitializerExample" -jar ~/Downloads/mockserver-netty-5.9.0-jar-with-dependencies.jar -serverPort 1080 -logLevel INFO', I have changed the path to jar to my local path, but did not change the initializationClass, I got an error 'java.lang.RuntimeException: java.lang.ClassNotFoundException: ExpectationInitializerIntegrationExample'. What should I do to fix this? Thanks!

@JuneWangC you can only use an initializationClass if it is in the classpath of the JVM otherwise it won't be visible to MockServer, if you run MockServer in embedded mode using the org.mockserver.integration.ClientAndServer class from within the same project containing the initialiser then you should find that easier, see: https://mock-server.com/mock_server/running_mock_server.html#client_api

Hi everyone. I get a timeout error trying to get requests on the following code from the examples. I increased the timeout to 60 sec set through ConfigurationProperties.maxSocketTimeout, but it did not help
Code:

HttpRequest[] recordedRequests = new MockServerClient("serverIp", 1080)
    .retrieveRecordedRequests(
        request()
    );

error:
[ERROR] Time elapsed: 42.308 s <<< FAILURE!
org.mockserver.client.SocketCommunicationException: Response was not received from MockServer after 35000 milliseconds, to wait longer please use "mockserver.maxSocketTimeout" system property or ConfigurationProperties.maxSocketTimeout(long milliseconds)
But getting the same information through api works - checked in postman. http://serverIp:1080/mockserver/retrieve?type=REQUESTS
What could be the problem?

Hi, what's the difference on docker hub between mockserver/mockserver repository and jamesbloom/mockserver repository? Which one should I use? Both refers to the same documentation but the documentation refers to mockserver/mockserver even if the latter has 1M+ pulls agains 100K+ of the official one

Hi everyone, I'm using MockServer to mock 50MB json responses. After a fixed number of responses (iirc ~25 responses), MockServer responds with 404 and then a short while later I get "Exception in thread "MockServer-EventLog0" java.lang.OutOfMemoryError: Java heap space". My mock is using a callback with a fixed static buffer, so I'm not creating it at every invocation of the callback. Is there something simple I can do to avoid this? MockServer is in a separate process, right? So how can I, from my junit rule, configure the heap size of the other process? Or is there something I can do to optimize the memory usage?

hi I created an expectation that mock-server gets a POST request with a gzipped body but when i actually send it a gzipped body the expectation fails. I also dont see my content-type : gzip header in mock-server logs. Is it because mock-server automatically unzips the body ?

@here, For an integration test, I am running 5 services, mocked using mockserver by spinning them up with docker compose. Here is my docker compose file:

version: "3.7"

I would like to get the logs of order-management-webapp for which I have increased the log level. How can I do that please?
The mockserver doc does not provide any details on getting logs when using docker-compose and I am very new to Mockserver. Thanks in advance for your answers!

@kapokmi the logs get printed out on the console so your’l need to look at the console logs for that container using docker-compose

hi, i am using mockServer.mockServerClient javascript client, my instance of mockserver is running behind an api proxy which needs extra authentification header, any way to use the javascript client in this case?

@sarut0bi This chat group has migrated to Slack if you would like to join the new Slack group please use the following link https://join-mock-server-slack.herokuapp.com/

@sarut0bi I think the setDefaultHeaders() function on the client should allow you to do what you need to set some default headers for proxy authentication

@jaqat you can't cast an array in java, you need to do something like the following Arrays.stream(requests).map(HttpRequest.class::cast).toArray(HttpRequest[]::new)

BTW I am using python/tavern to test my APIs with mock server and the API creates some data and passes it to mockserver which will use it to create a response...

hi all

@fduminy

I am trying to record request and response of a REST server. I ran command "mvn -Dmockserver.serverPort=1080 -Dmockserver.proxyRemoteHost=8060 -Dmockserver.logLevel=INFO org.mock-server:mockserver-maven-plugin:5.11.1:runForked" and can browse "http://127.0.0.1:1080/mockserver/dashboard". But I can't call my webservice replacing only the port by 1080 in the URL. What's wrong ?

for example, when using http://127.0.0.1:1080/Api/swagger-ui.html instead of http://127.0.0.1:8060/Api/swagger-ui.html I got a 404 error

Fabien DUMINY

@fduminy

in the dashboard, I see my request in received request panel and I see "NO_MATCH_RESPONSE" in the log panel. any idea what's the problem ?

Fabien DUMINY

@fduminy

I found the problem : I was setting proxyRemoteHost instead of proxyRemotePort

Fabien DUMINY

@fduminy

hi all

Fabien DUMINY

@fduminy

I captured requests and responses and saved it as a json. I would like to verify that actual request and responses matches with java code : I call initializationJsonPath(expectations) and call the WS to test. I modified the json file of expectations but that still match actual requests/responses

Fabien DUMINY

@fduminy

I see that activeExpectation is empty. It's like if my file wasn't loaded despite I see "loading JSON initialization file: "mockserverInitialization.json" in the logs

Fabien DUMINY

@fduminy

Hi @jamesdbloom. Do you have an example showing how to run mockserver both as a proxy and as a verifier using a json file with expected request & response ?

DenisSerebryansky

@DenisSerebryansky

Hi guys

My goal is to setup HTTP server mock in code and then reach this mocked server from remote (in my case from within docker container).
After start of my mocked server (startClientAndServer(1180)) I can reach it from local host machine, but not from remote (curl -XGET http://host.docker.internal:1180/ from within container leads to "Connection refused" error, whereas I can easily reach another service launched on my host machine)

How should I configure my mock-server in order to make it available from remote?

Wagner Caetano

@WagnerCaetano

Hey Guys,
i want to know if there's a way of converting the requests body charsets from retrieveRecordRequests because those body are in a different charset that i'm comparing , for example the expect is às and the incoming is Ã s and my request is being made as expected. (Btw i updated mock server version , it was on 5.6.1 now it's on 5.11.0 and use to work well on 5.6.1)

Hi Guys,

Can anyone please tell me How can I create POST request expectations with JSONPATH with multiple fields in request body.

I am able to create expectation for get end point but not sure How I can call endpoint for post request with multiple fields with JsonPath or any other way to create it.

My Post request that I want call in postman.
http://localhost:8080/api/xyz?simulation=false
Body:
{
"alias": "Mister XYZ",
"accountId": "BE122",
"accountType": "IBAN", //this is ENUM
"address": {
"countryCode": "BE"
}
}

And for this I am creating expectation like below
( It created successfully with 201 created ):

PUT: http://localhost:8080/mockserver/expectation
Body:
"httpRequest": {
"path": "/api/xyz",
"method": "POST",
"queryStringParameters": {
"?simulation": ["false"]
},
"headers": {
"Content-Type" : [ "application/json" ],
"Authorization": ["Bearer .+"]
},
"body": [
{
"type": "JSON_PATH",
"jsonPath": "$[?(@.['alias'] == 'Mister XYZ')]"
},
{
"type": "JSON_PATH",
"jsonPath": "$[?(@.['accountId'] == 'BE122')]"
},
{
"type": "JSON_PATH",
"jsonPath": "$[?(@.['accountType'] =~ /(IBAN|BAN|BBAN|OTHER)/)]" //these are ENUMs
}
{
"type": "JSON_PATH",
"jsonPath": "$.['address'].[?(@.['countryCode'] == 'BE')]"
}
]
},
"httpResponse": {
"statusCode": 201,
"headers": {
"Content-Type": ["application/json"]
},
"body": {
"id": "5a0eaf2012a9a12f1c98947a"
}
}
}

Also give me some solution for ENUM type of fields like accountType in above request. How can I handle it?

Please let me know if you want more clarification on this problem.

Hi all, I'm having some trouble with my expectations not aligning with what I want. I have my mock server set to respond with mock data when requested on 4 different paths, all GET requests. But for some reason the path it expects turns out to be different from the path it gets every time causing it to fail, but there's no way for me to figure out why its contacting the wrong path in the first place

org.mockserver.logging.MockServerLogger [MockServer-EventLog0] INFO  13030 request:

  {
    "method" : "GET",
    "path" : "/services/rest/server/containers/test_1.0.0/processes",
    "queryStringParameters" : {
      "pageSize" : [ "1000" ],
      "page" : [ "0" ],
      "sortOrder" : [ "true" ]
    },
    "headers" : {
      "Host" : [ "localhost:13030" ],
      "Connection" : [ "Keep-Alive" ],
      "User-Agent" : [ "Apache-HttpClient/4.5.12 (Java/15.0.1)" ],
      "Accept-Encoding" : [ "gzip,deflate" ],
      "content-length" : [ "0" ]
    },
    "keepAlive" : true,
    "secure" : true
  }

 didn't match expectation:

  {

        "status" : [ "1" ],
        "pageSize" : [ "1000" ],
        "sortOrder" : [ "true" ]
      }
    },
    "times" : {

    },

      "headers" : {
        "content-type" : [ "application/json" ]
      },
      "body" : ...

the paths seem to be mismatched but I have no idea why

@j-lucas-d

Hi. A question for the room; I need to configure a mock-server with multiple expectations, which all use the same path. They have different HTTP methods and URL parameters. From my testing, it seems the mock server is only keeping the last expectation. Is there a way to have them all configured?
