Hello! I'm not sure how WireMock behaves with query parameters and I couldn't find any info about it. What I want to know is if I need to create two stubs when my endpoint has optional parameters... do I need to create one stub with the parameter and another one without it?

Does the fact that the query parameter is or isn’t there impact the response for your situation? If so, I’d create two responses to keep things simple. If not, you can just ignore the query parameter.

how do I ignore it? If I don't define a query paremeter will the stub match if the method and path match?

If you use

urlPathEqualTo()

or

urlPathMatching()

query parameters will be ignored. See https://wiremock.org/docs/request-matching/#url-matching

I'm using

urlPathTemplate

because I need to extract some info with regular expressions... would query parameters be ignored in that case? Sorry I have so many questions, just starting with WireMock and I have not been able to find this info

No worries, we’re here to help.

urlPathMatching()

takes a regex if I recall correctly. Are you defining responses in code or in JSON files?

JSON, I'm defining a ConfigMap with my stubs in JSON and WireMock is picking that up

I think you’re looking for `urlPathPattern`: https://wiremock.org/docs/request-matching/#regex-matching-on-the-path-only

ok, so what about using a patter to match the path but also matching query parameters... is that not possible?

Sure, you can combine multiple matchers easily

ok so in this case

"request": {
    "method": "GET",
    "urlPathTemplate": "/v1/profiles/{profileId}/groups",
    "pathParameters": {
      "profileId": {
        "matches": "[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}"
      }
    },
    "queryParameters": {
      "space": {
        "matches": "[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}"
      }
    }
  }

The stub would match a GET to any url with a path that matches that regular expression with a parameter (space) which must be there... am I right?

I think so, yes, but it’s hard to know for sure without testing
