Hi Team, Can I know how I can verify if a particular field has a specific value where this field can be present anywhere in the response (within array/objects). I tried below but the pact file generated fails at provider side

val pactBody = PactDslJsonBody()
    .stringMatcher("test", "^(test1|test2)$")

what do you mean, sorry?

Consider below is my response, I wanted to verify that test_type is either test1 or test2 it being present anywhere in the response.

"tests": [{
          "test_type": "test1",
          "tests": [{
            "test_type": "test2",
            "test": {
              "test_type": "test3",
              "tests": [{
                "test_type": "test4",
                "image": {
                  "assetId": "runway_brand_flying_roo_platinum"
                }
                }
              }
            }

That's not what Pact is designed to do. It is designed to confirm that the entire response conforms to a contract.

We have a complicated response where in objects are nested and hence can't really verify the entire response confirms to a particular contract

It must have some shape, otherwise how does the client know how to parse it? If you were to describe it as OAS or JSON schema, is that possible?

Here is how the schema for the above looks

tests*  [Test{
isConsistent* boolean
id$regression_tests  string
}]

sorry what is that syntax? do you have JSON schema or the OAS for it?

Sorry, I don't think we have one

you can put a constraint on

test_type

as a property, but the way you framed it is that it could appear anywhere in the response at any level - this feels very “loose” and I don’t think Pact would be able to support it. If it is a structured object, then it’s probably testable. So I was just trying to understand the model. I don’t know this syntax, so would just be guessing what it is:

tests*  [Test{
isConsistent* boolean
id$regression_tests  string
}]

I think it might be something like this:

{
  "tests": [
    {
      "isConsistent": true,
      "id$regression_tests": "some string"
    },
    {
      "isConsistent": true,
      "id$regression_tests": "some other string"
    }
  ]
}

If this structure, you could apply a constraint to

id$regression_tests

in the way you’re describing.
