does anyone have experience with using this Wiremock CSV extension? I am trying to set it up in Wiremock Open Source (in Docker). https://github.com/massamany/WireMockCsv I've got the extension

.jar

in the

/var/wiremock/extensions

folder, but it doesn't seem to load the extension (rebuilt image, recreated container, and startup log displays all my other exceptions but not this one) edit - answered my own question 🙂

Hi all,

I'm using wiremock in standalone mode to proxy request to another server and to remove the Authorization header before sending the request to the other server. The proxy works well but the Authorization header is not remove. I start wiremock with this command line:

java -jar .\wiremock-standalone-3.13.0.jar --print-all-network-traffic

I have a json file in the mappings directory that configure the proxy and should remove Authorization header:

{
  "request": {
    "method": "POST",
    "url": "/notification"
  },
  "response": {
    "proxyBaseUrl": "<http://localhost:8081>",
    "removeProxyRequestHeaders": [
      "Authorization"
    ]
  }
}

but at the end, the Authorization header is still sent to the final server did I miss anything?

Hi Team , I received this error when I tried to create a stub which has dynamic response based on the value of a query parameter sent in the request. Here's the Stub creation request :

curl --request POST \   --url <http://localhost:8080/__admin/mappings> \   --header 'content-type: application/json' \   --data '{   "priority": 15,   "request": {     "method": "GET",     "urlPath": "/reports/awb/tracking",     "queryParameters": {       "clientId": {         "equalTo": "323245"       },       "language": {         "equalTo": "en"       },       "awb[]": {         "matches": ".+"       }     }   },   "response": {     "status": 200,     "headers": {       "Content-Type": "application/json"     },     "jsonBody": {         "status": "success",         "data": [           {             "awbNumber": "{{request.query.awb[0]}}",             "content": "test",             "confirmation": {               "name": "test",               "date": "2023-03-06 13:58"             },             "returnAwbNumber": null,             "events": [               {                 "id": "H4",                 "name": " Shipment sorted on the belt",                 "location": "Bucharest",                 "date": "2023-03-01 04:46:46"               },               {                 "id": "H10",                 "name": " Shipment in transit towards the destination warehouse ",                 "location": "Bucharest",                 "date": "2023-03-01 05:19:10"               }             ]           }         ]       },     "transformers": [       "response-template"     ]   },   "persistent": true }'

I have deployed Wiremock using Flux (kubernetes) and I am using the below arguments :

args:
  - "--no-request-journal"
  - "--disable-request-logging"
  - "--max-template-cache-entries=50"
  - "--local-response-templating"
  - "--root-dir"
  - "/mnt/azure"

not sure why "--local-response-templating" does not work in this case. Could you please let me know how I can fix this 🙂 .

Hi, I'm trying to implement a custom WebhookTransformer to sign a request body with a secretKey. The transformer is porperly invoked before dispatching the webhook. But it is always invoked as soon as the transformer is registered. Is it possible to limit invocation only to stubs where it is explicitly defined? Code of the transformer:

public class WebhookSigningExtension implements WebhookTransformer {


    @Override
    public WebhookDefinition transform(ServeEvent serveEvent, WebhookDefinition webhookDefinition) {
        System.out.println("WebhookSigningExtension: transform called");
        return webhookDefinition;
    }

    @Override
    public String getName() {
        return "webhook-signer";
    }
}

Code to test the transformer:

public class Main {

    public static void main(String[] args) {
        WireMockServer wireMockServer = new WireMockServer(
                WireMockConfiguration.options().port(8080).extensions(new WebhookSigningExtension())
        );

        wireMockServer.start();

        wireMockServer.stubFor(<http://WireMock.post|WireMock.post>(WireMock.urlPathEqualTo("/webhook"))
                .willReturn(WireMock.ok())
                .withServeEventListener("webhook", Webhooks.webhook()
                        .withMethod(<http://RequestMethod.POST|RequestMethod.POST>)
                        .withUrl("<http://localhost:9898/webhook/test>")
                        .withHeader("Content-Type", "application/json")
                        .withBody("{ \"result\": \"SUCCESS\" }"))
        );

    }
}

Do I have to implement the logic to enabled/disable the transformer by passing custom parameter? Thanks in advance, Claudio

Hello, I've got a bit of an issue deploying wiremock as an appservice in azure... We're using wiremock to act as a stub for a training mode in our app. The plan was to build our own image with the json config baked in, that works fine locally. It also works fine when I build/push to our azure container registry from our pipelines and pull locally. Now when it comes to deploying into an azure app service, the server responds but all of our mapping config isn't in the

home/wiremock

directory anymore, it's exactly the same image as the one I pulled and tested locally. Any ideas what's going on here or potential avenues of investigation?

Hey folks, so I'm getting to grips with WireMock, I'm using the Java version 3.12.1 in a Kotlin project with the GraphQL extension. The thing I'm having trouble with is the

BackingStore

. I've read that it is specified in the options when we initialise a WireMockServer like this:

WireMockConfiguration config = WireMockConfiguration.options()
    .port(8080)
    .backingStore(new FileBasedBackingStore("wiremock_data"));
WireMockServer wireMockServer = new WireMockServer(config);
wireMockServer.start();

Where the

FileBasedBackingStore

is imported from here:

com.github.tomakehurst.wiremock.store.file.FileBasedBackingStore

. However the package structure has changed since then. Is the BackingStore no longer a thing? Best wishes and many thanks in advance.

Hello everyone. I have following setup. While this works fine for a keystore with just one keypair inside, it does not when my keystore has multiple values. I dont find a way to configure, which alias to choose. I already wanted to create a Merge Request for it but I cant build it. So question first here: Is there currently really no way to configure the alias to choose from a keystore? Actually keystores are used to store multiple keys, arent they?

wireMockConfig()
.[...]
.keystorePath(<somePath>)
.keystoreType(KEYSTORE_TYPE)
.keystorePassword(KEYSTORE_PASSWORD)

Hello, We are using Spring Boot. For integration Testing we are using Cucumber with WireMock. We want to implement recording and playback feature in our integration tests. We have our mocks added to

mappings

and

__files

folders. When

Recording

is enabled we could see actual API call is being made and

recordings/stubMappings

are saved in

mappings

and

__files

, but we want to update existing

mappings

instead of creating

new files in mappings and __files

folder. Can someone let us know if it is possible?

Hello, I need to start a wm server using standalone jar, along with it I have to add the behavior of wm extensions to the same server. But I cannot use custom extension jar as the remote machine I am using doesn't allow custom jars to be stored in it for security reasons. I'm currently exploring the ways to add extensions without using the jar (by using .class files or something) Can someone help me with this?

Hello, How can we mention in request mapping if a query parameter should not be null or mandatory Currently I have defined query parametere like

"urlPathPattern": "/v3/item*",
"queryParameters": {
  "item": {
    "doesNotMatch": "^00000000[1-2]$"
  }
}

but it's also matching with another type of request

"urlPathPattern": "/v3/item*",
"queryParameters": {
  "product": {
    "equalTo": "12312321421"
  }
}

My understanding is that because in second json request item is null but it's satisfying condition for

"doesNotMatch": "^00000000[1-2]$"

which is why wiremock is responding with stub mapped to first reques while ideally it should respond with stub for second mapping. I know with priority this can fixed but in my application already priorities are set and getting messed up. Does wiremock provide anything for such scenario ?

Hello, i am using record/ playback, i am recording multiple url's same time, i want a specific url to stop recording based on conditions is there anyway to do it, i am using wiremock standalone 3.10.0 version in spring boot

Hello, I would like to ask about using WireMock. It uses a proxy to send requests to the target server, but the server has IP restrictions, allowing only certain IPs to access it. Thus, I can't send requests using the WireMock proxy. Is there a way to resolve this issue?

Hi there, could please someone help me with the docker & createNewStub issue, I'll add now some details in the thread

i'm trying to use wiremock to facilitate mocking a variety external apis in tests via recordings/replay (something like ruby's vcr library). what would be the simplest set of wiremock extensions (or better yet, built-in functionality) to capture and pass something like a uuid through a sequence of requests obtained via recording, such that the recording can be played back in a uuid-independent way. would a

StubRequestFilterV2

be suitable for doing something like this? one that re-writes the body the of the requests using information passed to the transformers via the specific test? (oops posted in the wrong spot, also details in thread)

Hi, I am having some trouble using the

absent

feature with

matchesJsonPath

when attempting to filter request logs. I'll explain below 👍 if I check equality of the

$.entitlementId

alone returns 1 request. Request:

POST /requests/count
{
    "method": "POST",
    "urlPathPattern": "/merchant-entitlement/ns/804c2d9f-3689-4095-8403-fd0525fb834b/entitlements",
    "bodyPatterns": [
        {
            "matchesJsonPath": {
                "expression": "$.entitlementId",
                "equalTo": "e331678d-160a-4530-a966-57341666b0b2"
            }
        }
    ]
}

Response:

200 OK

{
  "count": 1,
  "requestJournalDisabled": false
}

So this is evidence that the property appears in the log and is equal. if I switch it to use

absent

My expectation is that this will check if the field itself exists - so I perform the following request:

POST /requests/count
{
    "method": "POST",
    "urlPathPattern": "/merchant-entitlement/ns/804c2d9f-3689-4095-8403-fd0525fb834b/entitlements",
    "bodyPatterns": [
        {
            "matchesJsonPath": {
                "expression": "$.entitlementId",
                "absent": false
            }
        }
    ]
}

Response:

200 OK

{
  "count": 0,
  "requestJournalDisabled": false
}

My thinking here that I am checking to ensure the property exists - which it does since the request first request for field equality returns a count of 1. If I change the above request to

"absent":"true"

I would expect it to return the above response like it does e.g

"count":0

. I've tried looking for more information about how

absent

works but haven't been able to locate it so I'm hoping someone here can support 🙏 thank you Further note: before I went down a bit of a rabbit hole here - my core requirement was to use this endpoint to ensure fields in requests do not exist e.g.

entitlementId == xyz && otherFields does not exist

I'm unsure if this is possible, and if not - is there another way? wiremock server - docker - wiremock:3.4.1-2

Hi all! So I'm running standalone WireMock and I've ran into a use case. I wonder if you guys can give me any insight. I'll leave it in the thread.

Hello. I want to use Wiremock to mock several parties. Let's say I have a payment service and there's integration with several PSP - Paypal, Ingenico, etc. So I want to use Wiremock to mock Paypal and Ingenico. I have a dedicated test environment to run my e2e autotests on it. Should I put 2 independent instances of Wiremock there? I.e., paypal-mock.mydomain.local and ingenico-mock.mydomain.local? What if I have 50 dependencies? Do I need to run 50 Wiremocks? Is it possible to mock 50 dependencies with one instance of Wiremock? I can route requests to different mappings with URL path or some header, but it doesn't seem to be a good solution (unnecessary changes to my app code). And I don't have any idea, how to route requests in other way.

Hi Wiremock users ! 👋 I’m using Wiremock for some Spring Boot API integration tests, with the JUnit

WireMockExtension

I’ve noticing that whenever the json to return is designated with a

bodyFileName

that points to a missing file, this error have WM server still returning an answer, but in text/html content type, with the call stack in the HTML body It’s somehow a bit puzzeling because whenever no stubs match the requested ressource, an error is produced in the log console ... if we use a

ConsoleNotifier

to get extra WM informations while tuning our test’s mocks Is there any way to configure the WM extension in order to also have the missing files exceptions being reported on the console ?

Hi, Request matching needs to separate out query params so we match only against the query param keys and not the values. Any suggestions on how to handle this? I tried Wiremock Extension to capture the stubs and modify the content with the regex but seems like its complicated. If I have 3 different query params and I need to match only the key for the first query param and leave the others.

I have upgraded WireMock.Net from version 1.4.9 to 1.8.9. After that i am facing an issue with SendAsync with Post method. It is always returning 404 "Not Found". It was working as expected which returning 200 "OK" Can some one please help me to fix the issue!

Good afternoon, I am trying to mock a grpc service in the standalone version of wiremock, but there seems to be something going wrong with the response encoding. This is my mapper:

{
  "name": "aanroep splunk geeft 200 OK",
  "priority": 5,
  "request": {
    "urlPath": "/nl.bkwi.audit.log.grpc.v0100.AuditLog_v0100Service/AuditLogRequest",
    "method": "POST"
  },
  "response": {
    "status": 200,
    "headers": {
      "content-type": "application/grpc",
      "grpc-status-name": "OK"
    },
    "body": "{\"message\": \"hi\"}",
    "transformers": [
      "response-template"
    ]
  }
}

this is what happens when I run a query:

grpcurl -plaintext \
        -d '{"key":"message1", "arguments":["argument1","argument2"]}' \
        -proto AuditServiceV1.proto \
-import-path target/protoc-dependencies/ec4b3d39b9b3c3f5186cf878d88e0a4e/nl/bkwi/specification/proto \

        localhost:8088  nl.bkwi.audit.log.grpc.v0100.AuditLog_v0100Service/AuditLogRequest

}

  Message: grpc: received message larger than max (577594739 vs. 4194304)

What could I be doing wrong? There is nothing in the logs indicating that something is going wrong

Hi everyone 👋 I'm using WireMock in standalone mode (via

wiremock-standalone.jar

), configured to act as an HTTPS proxy using:

--https-port 8443 --enable-browser-proxying

I noticed that WireMock generates a dynamic self-signed CA, and exposes the root certificate at:

/__admin/certs/wiremock-ca.crt

This works fine, I can trust the CA in my clients and avoid SSL errors when intercepting HTTPS traffic. However, I'm looking for a way to use a custom or persistent CA, so I don’t have to re-export and re-trust the CA every time WireMock restarts... Does anyone know if there's a way to: 1. Provide a custom CA in standalone mode? 2. Or at least reuse a previously generated CA? I’m aware this can be done when embedding WireMock as a Java library (

caKeystorePath

, etc.), but I’d prefer to keep using the standalone JAR if possible. Thanks in advance!

Hi Team - (Reposting)Would love to hear your thoughts on this. Request matching needs to separate out query params so we match only against the query param keys and not the values. Any suggestions on how to handle this? I tried Wiremock Extension to capture the stubs and modify the content with the regex but seems like its complicated. If I have 3 different query params and I need to match only the key for the first query param and leave the others.

Am I confusing myself here, or should it be possible to have a standalone wiremock server in docker (ie. wiremock/wiremock:latest) but then access the admin API using a C# client? Can I use the WireMock.Net.RestClient nuget or does that only work with a WireMock.Net docker service?

Hi Team, Am facing an issue with wiremock. Have mocked couple of endpoints using wiremock and deployed it in docker. Am able to access the get and post endpoints through chrome and postman, could able to see the log messages generated in wiremock docker container. I have java application running in docker container, when it is hitting the mocked api endpoint not getting response/ error. Didn't find any trace in the wiremock logs. Would you please suggest me a documentation/ your comments on this.

Hello Team , TIA Need help setting up xmx value in wiremock container in kubernetes , wondering what option should be used whether it is

JAVA_MEM_OPTS

or

JAVA_OPTS

Context : Although the overall memory utilisation is not even 60% of the container as i set the mem limit to 400Mib in resources under k8 but it is giving me OOM error when hitting it

HTTP ERROR 500 java.lang.OutOfMemoryError: Java heap space

heya, when generating stub mappings for a recording,

serveEventsToStubMappings

in the Recorder generates the stub mappings from the serve events in reverse-chronological order, and thus passes them to the transformer in reverse-chronological order. is this expected and/or intentional? is it something that you'd accept a patch for? alternatively, is there an existing extension point to customize this order? i'm writing an extension that matches & propagates data through the sequence of requests. it depends on being able to capture data from requests earlier in the chronology to match that data in requests later in the sequence, so it's a bit of a show-stopper for me 😅. i can think of a hack or two (probably storing all the stub mappings passed to the transformers in a list of my own, figuring out when the last call happens, and re-sorting/processing them all during that final call) but i'd like to avoid it if possible.
