Hello there! I’m seeking for help building my stubs. Currently I have the following working:

{
      "request": {
        "method": "GET",
        "urlPath": "/service/api/v1/user/username/user%40my-company.com/"
      },
      "response": {
        "status": 200,
        "bodyFileName": "abc_getUserByUsername_user%40my-company.com.json",
        "headers": {
          "Content-Type": "application/json"
        }
      }
    },
    {
      "request": {
        "method": "GET",
        "urlPath": "/service/api/v1/user/username/user-high-clv%40my-company.com/"
      },
      "response": {
        "status": 200,
        "bodyFileName": "abc_getUserByUsername_user-high-clv%40my-company.com.json",
        "headers": {
          "Content-Type": "application/json"
        }
      }
    },
    {
      "request": {
        "method": "GET",
        "urlPath": "/service/api/v1/user/username/user-non-high-clv%40my-company.com/"
      },
      "response": {
        "status": 200,
        "bodyFileName": "abc_getUserByUsername_user-non-high-clv%40my-company.com.json",
        "headers": {
          "Content-Type": "application/json"
        }
      }
    }

I’m trying to simplify it using

urlPathPattern

, I managed to do it in other mocks but not here:

{
  "request": {
    "method": "GET",
    "urlPathPattern": "/service/api/v1/user/username/()/"
  },
  "response": {
    "status": 200,
    "bodyFileName": "abc_getUserByUsername_{{request.pathSegments.[5]}}.json",
    "headers": {
      "Content-Type": "application/json"
    }
  }
}

The part with

()

is where I’m trying to add the regex, but I tried many variations without success

a nicer solution than regex may be to use

urlPathTemplate

like so,

{
  "request": {
    "method": "GET",
    "urlPathTemplate": "/service/api/v1/user/username/{username}"
  },
  "response": {
    "status": 200,
    "bodyFileName": "abc_getUserByUsername_{{request.path.username}}.json",
    "headers": {
      "Content-Type": "application/json"
    }
  }
}

I’m using the

spring-cloud-starter-contract-stub-runner

and that doesn’t seems to work

ah okay. then

"urlPathPattern": "/service/api/v1/user/username/(.*)/"

doesnt work?

I’m afraid it doesn’t 😞

"urlPathPattern": "/service/api/v1/user/username/.*/"

?

That doesn’t work either. I tried so many regex that I lost the count

are you seeing an error?

I don’t see an error. But the tests fail because that stub is not matching the request I’m doing

it's returning a 404?

I don’t know what’s returning. The problem is that I enabled logs but I dunno what’s happening as I don’t see any in the console. I’m afraid the trailing slash is necessary 😞

does the request being sent to the wiremock server definitely contain the trailing slash in its url?

As you can see in the original stubs I share, they have it

im not referring to the stubs, im referring to the request that is being sent to the wiremock server in your test that's failing

I can’t see anything in the logs:

logging:
  level:
    com.github.tomakehurst.wiremock: DEBUG
    org.springframework.cloud.contract.wiremock: DEBUG

what does your failing test look like?

I perform a request with MockMvc, and then I perform some assertions in the end. When changing the stub, I get errors:

org.opentest4j.AssertionFailedError: Expected value to be true.

The endpoint is definitely returning a 404, since I have a catch for that

i want to know what the url that the request your test is performing is

I’m not getting more information in the logs. The stubs with the urlPath added above are working fine, so I assume those are the requests the tests are performing

on the cli you can use

--verbose

I ran debugging, and it seems that the issue is coming from here, since the file couldn’t be found:

"bodyFileName": "abc_getUserByUsername_{{request.pathSegments.[5]}}.json",

having you enabled the response templating extension?

I did creating a bean, it works fine for other stubs:

@Bean
    fun wireMockConfigurationCustomizer(): WireMockConfigurationCustomizer {
        return WireMockConfigurationCustomizer { config: WireMockConfiguration ->
            config.extensions(ResponseTemplateTransformer(true))

what's the value you're putting in the path segment? does that abc_getUserByUsername_[YOUR_PATH_SEGMENT_VALUE].json exist?

This is the error I can see, unfortunately I cannot read the filename:

feign.FeignException$InternalServerError: [500 Server Error] during [GET] to [<http://localhost:11235/service/api/v1/user/username/user%40my-company.com/>] [ServiceClient#getUserByUsername(String)]: [{
"servlet":"com.github.tomakehurst.wiremock.servlet.WireMockHandlerDispatchingServlet-7385c2f0",
"cause0":"java.io.FileNotFoundException: /Users/name/git/service/src/test/... (596 bytes)]

can you put a breakpoint into where the response is received and read the response body yourself?

I think I got it, in the response, the username is picked up with the ‘@’ instead of ‘%40’

okay that'll be because the url path segments are being decoded by wiremock. this is expected behaviour. changing your filenames to use

@

symbols should fix it

Yeah, I did work

are you referring to the original stubs in your first message?

Yes, in any case. I managed to fix it. Thanks!

no worries
