how to solve au.com.dius.pact.consumer.PactMismatchesException

[linda...@gmail.com]

Hi all,

I am new to Pact. I was trying to create a contract for 2 of our microservices. The producer returns a JSON with 3 lists and a message, and this is what I have specified in the createFragment() method.

My class is below

public class PactForDevice {
    Map<String, String> headers = MapUtils.putAll(new HashMap<String, String>(), new String[]{"Content-Type", "application/json;charset=UTF-8"});

@Rule
public PactProviderRuleMk2 provider = new PactProviderRuleMk2("device-service-m", this);

@Pact(consumer = "device-r", provider = "device-service-m")
public RequestResponsePact createFragment(PactDslWithProvider builder) {

    return builder
            .given("Device M details")
            .uponReceiving("retrieving Device details")
            .path("/devices/v1")
            .method("GET")
            .query("externalId=0942dc67-35de-44f7-a061-743f59436a98")
            .willRespondWith()
            .headers(headers)
            .status(200)
            .body("{" +
                    "\"data\": [,\n " +

} 

As the first step after writing this class, I am trying to run it, but it gives me this exception

au.com.dius.pact.consumer.PactMismatchesException: The following requests were not received:

method: GET

path: /devices/v1

query: [externalId:[0942dc67-35de-44f7-a061-743f59436a98]]

headers: [:]

matchers: MatchingRules(rules=[:])

generators: Generators(categories={})

body: OptionalBody(state=MISSING, value=null)

Please help me to resolve this issue.

I have also asked this question on Stack overflow :
