pact-net: Matching rules against field name with a '.' character are not working

Hi,

I’m currently trying to test a contract with an Odata v4 endpoint.

As part of the Odata json format specifications the server usually includes information other than the raw data in the response called annotations.

Annotations are name/value pairs that have a dot (.) as part of the name, an example could be

"@odata.context": "http://localhost/$metadata#MyEntity/$entity"

Obviously I’m not interested in the exact value of the annotations field so I’m using type matchers and my pact looks something like:

{ "consumer": { "name": "OdataConsumer" }, "provider": { "name": "OdataProvider" }, "interactions": [ { "description": "A GET request to retrieve an Odata entity", "request": { "method": "get", "path": "/odata/MyEntity('1234')" }, "response": { "status": 200, "headers": { "Content-Type": "application/json; odata.metadata=minimal", "OData-Version": "4.0" }, "body": { "@odata.context": "http://localhost/$metadata#MyEntity/$entity", "anotherField": "someDataHere" }, "matchingRules": { "$.body.@odata.context": { "match": "type" }, "$.body.anotherField": { "match": "type" } } } } ], "metadata": { "pactSpecification": { "version": "2.0.0" } } }

As you can see the matching rule is not correctly escaping the annotation name and, as a result, it won’t be executed. My understanding is that the (.) is interpreted as a path separator.

Is there any way to fix this behavior having matching rules working against fields with a (.) as part of their names?
