Mapping adding order matters for multiple mappings?

[gregoks]

hi,

I have a weird behavior for these 2 mappings that I'm adding.

I'm sending the following request:

body:

<xml>555</xml>

headers:

SOAPAction ->http:https://tempuri.org/IService/DecryptByKeyType
Content-Type -> text/xml

I'm creating 2 mappings (dont mind the mapping guids):

{
    "Guid": "2453d1d1-d64f-4f7b-b0bd-e58aa0451094",
    "Priority": 1,
    "Request": {
      "Methods": [
        "POST"
      ],
      "Headers": [
        {
          "Name": "Content-Type",
          "Matchers": [
            {

              "IgnoreCase": true
            },

        },

              "IgnoreCase": true
            }
          ]
        }
      ]
    },
    "Response": {
      "StatusCode": 200,
      "BodyDestination": "SameAsSource",
      "Body": "<a:DecryptedValue>5678</a:DecryptedValue>",

        },

              "IgnoreCase": true
            },
            {
              "Name": "WildcardMatcher",
              "Pattern": "\"http:https://tempuri.org/IService/DecryptByKeyType\"",
              "IgnoreCase": true
            }
          ]
        }
      ],
      "Body": {
        "Matcher": {
          "Name": "RegexMatcher",
          "Pattern": "^.*555.*$",
          "IgnoreCase": false
        }
      }
    },
    "Response": {
      "StatusCode": 200,
      "BodyDestination": "SameAsSource",
      "Body": "<a:DecryptedValue>1234</a:DecryptedValue>",
      "Headers": {
        "Content-Type": "text/xml"
      }
    }
  }

The thing that it seems that if I add the first mapping first then its get caught and the other way around then the 2nd mapping gets caught:

example of the admin/requests when first mapping added first:

Can you please check if I'm missing anything?

[StefH]

The first doesn't have a match on body. Is that intended?

[gregoks]

Yes. I want to have 2 mappings where one more strict with specific body and the other more general for requests without such body

[StefH]

I see.

The code does just take the first available match:
https://github.com/WireMock-Net/WireMock.Net/blob/master/src/WireMock.Net/Owin/MappingMatcher.cs#L48

Maybe it a good idea to also take into account the number of successful matches.

[gregoks]

Oh so it does not matter the total score of the matchings? I would assume that it should return the best matching available and not the first one..

[StefH]

@gregoks
Can you try version WireMock.Net.1.0.30-ci-11883 on MyGet?

[gregoks]

Ill try. Does it include the other bug fixes? Because I already use the WireMock.Net.1.0.31-ci-11865 version.

[StefH]

No, this one is only this fix.

The #339 is not included here.

[gregoks]

I've tested and its working in WireMock.Net.1.0.30-ci-11883 version. Thanks!!

Do you have an ETA for version that will include all of the current open bug fixes?

Thanks,

Greg

[StefH]

No ETA, yet.

Please keep a watch on this project + Nuget.
