Hi, I'm trying to write a pact for an API using PactJS and TypeScript. The API uses Map, where the Key is an ID (uuid) and the Value will be an object I need to match. As it's unknown what the ID is I can't really write the body out in the

addInteraction()

method (

willRespondWith

). But the resulting pact-json file would have the expressiveness to do what I want. I can't find a matcher that would yield the

matchingRules

that I'm looking for. As an example: Instead of

"$.body.angebote.CLASSIC.angebotStatusFachlich": {
   "match": "type"
},
"$.body.angebote.COMFORT.angebotStatusFachlich": {
   "match": "type"
},

I would like it to generate:

"$.body.angebote.*.angebotStatusFachlich": {
   "match": "type"
},

Another example:

merkmale: {
    DOMIZILLAND_VN: {
        art: 400054,
        code: 40,
    },
    MERKMAL_PARTNERART_VN: {
        art: 432,
        code: 433,
    },
},

=> The keys will vary (DOMIZILLAND_VN, MERKMAL_PARTNERART_VN), so I would like to be able to generate rules like:

"$.body.merkmale.*.code": {
   "match": "type"
},

We're currently using Pact 9.x - anything in there that would allow me to write the pact-test in a spec-File that will actually produce matching rules with wildcards? Manually writing the pact-files is not really maintainable. Would there be a solution in 10.x? I saw on github discussions about eachKey-Matchers and I think that goes in the right direction, but I could not find that in the API for 9.x (I read that this kind of API is supposedly bad design, but it works really good with JavaScript/TS Frontends and it is now what it is.) Any help is appreciated.

You’re right, 9.x.x won’t have this matcher

eachValueLike()

sounds exactly like the thing I need.

Can I use 10.x to generate v2-Pact-Files?

Yes, but not if you use the

eachValueLike

matcher.

I switched to pact-js v11 and now I can use

eachKeyLike

(could not find an

eachValueLike

except in a github-issue discussion) It seems like the resulting

matchingRules

are broken. Is that a know issue? I have the following Interaction:

await provider
        .given('Server is healthy')
        .uponReceiving('a request to create a new Angebot for Rechtsschutzversicherung-Unternehmen')
        .withRequest({
            method: 'POST',
            path: `/vvn/kaufen-b2c/rest/angebote/rechtsschutzversicherung-unternehmen/v2/neugeschaeft`,
            query: { forceCaptcha: 'false' },
            headers: {
                'x-user-id': 'Z123456',
                'x-caller': 'pact-verification',
                'x-fall-id': fallid,
                'Content-Type': 'application/json',
            },
            body: angeboteErstellenNeugeschaeftRsvUnternehmen as any,
        })
        .willRespondWith({
            status: 200,
            headers: {
                'Content-Type': 'application/json',
            },
            body: {
                angebote: MatchersV3.eachKeyLike('CLASSIC', {
                    angebotStatusTechnisch: MatchersV3.string('TECHNISCH_KONSISTENT'),
                }),
            },
        });
});

Resulting

matchingRules

:

"matchingRules": {
  "body": {
    "$.angebote": {
      "combine": "AND",
      "matchers": [
        {
          "match": "values"
        }
      ]
    },
    "$.angebote.*.*": {
      "combine": "AND",
      "matchers": [
        {
          "match": "type"
        }
      ]
    }
  },
  "header": {}
},

$.angebote.*.*

is wrong. It should IMHO be:`$.angebote.*.angebotStatusTechnisch`
