Hey, thanks for the nice library! I've mocked a response and now want to add a dynamic ID into it. From what I understand this works by adding 
"transformers": ["response-template"],
into the mapping and the placeholder (e.g. 
{{randomValue type='UUID'}}
) into the response itself. I put 
mapping
and 
__files
in a subfolder 
myservice/src/test/resources/api/client/mockedapi/__files/response-POST-api-v1-users.201.json
and 
myservice/src/test/resources/api/client/mockedapi/mappings/mapping-POST-api-v1-users.201.json
.
Copy code
{
  "priority": 100,
  "request": {
    "urlPath": "/api/v1/users",
    "method": "POST"
  },
  "response": {
    "status": 201,
    "bodyFileName": "response-POST-api-v1-users.201.json",
    "headers": {
      "Content-Type": "application/json"
    }
  }
}
When adding the transformer attribute 
"transformers": ["response-template"]
, the response file is not found anymore as it tries to find the 
__files
in the test resource root 
myservice/src/test/resources/__files/response-POST-api-v1-users.201.json
I'm assuming I'm using it wrong, but what is the right config? Help is appreciated 🙏

Can you share the final stub JSON and the exact input and response you’re seeing?
m
initially the 
__files/response-POST-api-v1-users.201.json
is
Copy code
{
  "id": "7a14af18-f28b-425e-bc4c-d181498fa0ba",
  "password": "9f75b626-9e39-4720-9ffd-b8215f21d45b",
  "email": "<mailto:test@example.com|test@example.com>"
}
then with templating it's
Copy code
{
  "id": "{{randomValue type='UUID'}}",
  "password": "9f75b626-9e39-4720-9ffd-b8215f21d45b",
  "email": "<mailto:test@example.com|test@example.com>"
}
with an added 
"transformers": ["response-template"],
in the mapping 
mappings/mapping-POST-api-v1-users.201.json
Copy code
{
  "priority": 100,
  "request": {
    "urlPath": "/api/v1/users",
    "method": "POST"
  },
  "response": {
    "status": 201,
    "bodyFileName": "response-POST-api-v1-users.201.json",
    "transformers": [
      "response-template"
    ],
    "headers": {
      "Content-Type": "application/json"
    }
  }
}
when started via docker-compose
Copy code
wiremock:
  image: "wiremock/wiremock:3.9.1"
  ports:
    - "18080:8080"
  volumes:
    - ./src/test/resources/api/client/mockedapi/:/home/wiremock/
  entrypoint: [
    "/docker-entrypoint.sh",
    "--global-response-templating",
    "--disable-gzip",
    "--verbose"
  ]
I get the right response:
Copy code
http POST localhost:18080/api/v1/users
HTTP/1.1 201 Created
Content-Type: application/json
Matched-Stub-Id: de589e05-6073-4f76-ae10-187439653c71

{
    "email": "<mailto:test@example.com|test@example.com>",
    "id": "bfbae7a3-9f68-4d1b-9580-904da27f906d",
    "password": "9f75b626-9e39-4720-9ffd-b8215f21d45b"
}
but doesn't find the response template when started via tomakehurst
Copy code
import com.github.tomakehurst.wiremock.common.ClasspathFileSource
import com.github.tomakehurst.wiremock.common.filemaker.FilenameMaker
import com.github.tomakehurst.wiremock.core.WireMockConfiguration.wireMockConfig

import com.github.tomakehurst.wiremock.standalone.JsonFileMappingsSource
import com.github.tomakehurst.wiremock.store.DefaultStores

object WiremockFactory {
    fun createExtension(path: String): WireMockExtension =
        WireMockExtension
            .newInstance()
            .options(
                wireMockConfig()
                    .dynamicPort()
                    .mappingSource(
                        JsonFileMappingsSource(
                            ClasspathFileSource("$path/mappings/"),
                            FilenameMaker(),
                        ),
                    ).withStores(DefaultStores(ClasspathFileSource(path))),
            ).build()
}
I get

which is using the wrong path Looking at the snippets above I assume I initiate WireMockExtension with wrong parameters
t
I think you need to remove the 
mappings/
from the path passed to the ClasspathFileSource constructor, as this path is the parent of mappings and __files.
m
I was able to fix the setup by replacing 
mappingSource
and 
withStores
with just 
withRootDirectory
Copy code
WireMockExtension
            .newInstance()
            .options(
                wireMockConfig()
                    .dynamicPort()
                    .withRootDirectory(filePath(path))
                    .templatingEnabled(true)
                    .globalTemplating(true),
            ).build()
and it works fine with and without templating. Thanks for the help!
