pact-jvm: org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [au.com.dius.pact.consumer.MockServer mockServer]
I am figuring out how to implement consumer driven contract testing using pact junit5. But the test keeps failing because of no parameter resolver for the injected MockServer, even though the test class is extended with PactConsumerTestExt. My understanding is the parameter resolver for MockServer should be provided with PactConsumerTestExt extension. Would be great if anyone could help me out here!!
Java version : 11
Spring boot version : 2.6.1
Pact library used :
<dependency>
<groupId>au.com.dius.pact.consumer</groupId>
<artifactId>junit5</artifactId>
<version>4.3.2</version>
<scope>test</scope>
</dependency>
My consumer pact test class with one interaction :
import au.com.dius.pact.consumer.MockServer;
import au.com.dius.pact.consumer.dsl.PactDslJsonBody;
import au.com.dius.pact.consumer.dsl.PactDslWithProvider;
import au.com.dius.pact.consumer.junit5.PactConsumerTestExt;
import au.com.dius.pact.consumer.junit5.PactTestFor;
import au.com.dius.pact.consumer.junit5.ProviderType;
import au.com.dius.pact.core.model.RequestResponsePact;
import au.com.dius.pact.core.model.annotations.Pact;
import com.divyaa.consumer.beans.Product;
import com.divyaa.consumer.services.ProductService;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import static org.junit.jupiter.api.Assertions.assertEquals;
@ExtendWith(PactConsumerTestExt.class)
public class AddProductPact {
@Pact(provider = "ProviderService", consumer = "ConsumerService")
public RequestResponsePact createPact(PactDslWithProvider builder){
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json; charset=utf-8");
PactDslJsonBody body = new PactDslJsonBody()
.stringType("id","10")
.stringType("type", "CREDIT_CARD")
.stringType("name", "Gem Visa");
return builder
.given("Product doesn't exist")
.uponReceiving("Add product")
.path("/products")
.method("POST")
.willRespondWith()
.status(200)
.headers(headers)
.body(body)
.toPact();
}
@Test
@PactTestFor(providerName = "ProviderService", providerType = ProviderType.ASYNCH)
public void example(MockServer mockServer){
Product expectedProduct = new Product();
expectedProduct.setId("10");
expectedProduct.setType("CREDIT_CARD");
expectedProduct.setName("Gem Visa");
List<Product> expected = Arrays.asList(expectedProduct);
String baseUrl = mockServer.getUrl();
RestTemplate restTemplate = new RestTemplateBuilder()
.rootUri(baseUrl)
.build();
Product product = new ProductService(restTemplate).addProduct(expectedProduct);
assertEquals(expected, product);
}
}
The above test fails with following error :
org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [au.com.dius.pact.consumer.MockServer mockServer] in method [public void AddProductPact.example(au.com.dius.pact.consumer.MockServer)].

I noticed I was using org.junit.Test instead of org.junit.jupiter.api.Test, but got the same error even after changing.
Tried using ParametrizedTest, but my test got ignored.
Connected to the target VM, address: '127.0.0.1:61332', transport: 'socket'
Test ignored.

If you’re using the
@TestTemplateparameterHttpRequestfromau.com.dius.pact.providerversion 4.3.x check that the import isorg.apache.hc.core5.http.HttpRequestbecause the oldorg.apache.http.HttpRequestversion was replaced, see the Pact JUnit 5 Extension docs.That worked! Thank you! And yeah, ProviderType.ASYNCH is not required in my case.
I had this issue this week. I think you’ll need to set the version to still use version 3 on your @pactFor method.
and not sure you should keep the ProviderType.ASYNCH part unless you’re testing for messages.
