Spring Cloud Contract org.junit.ComparisonFailure: expected: <[200]> but was:<[404]> while running tests - spring-cloud-contract

Question

I've setup a sample project to use Spring Cloud Contract 2.0.0.RC1 just to get it working. When I run the tests I receive the error message:
Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.188 sec <<< FAILURE!
validate_shouldGetProfile(com.example.contractdemoserver.ContractdemoserverTest) Time elapsed: 0.443 sec <<< FAILURE!
org.junit.ComparisonFailure: expected:<[200]> but was:<[404]>
at com.example.contractdemoserver.ContractdemoserverTest.validate_shouldGetProfile(ContractdemoserverTest.java:27)
The project builds and runs fine otherwise. I've tried numerous things to resolve this test error including checking to see if the ContractVerifieriBase is being called by adding a System.out.println() message to Contractdemoserverbase.setup() (see below), and it is being called.
I've been trying to follow/emulate just the producer project from here (which runs and tests fine):
https://github.com/spring-cloud-samples/spring-cloud-contract-samples
What am I doing wrong?
Project Structure is laid out in idea like so:
ContractdemoserverApplication:
package com.example.contractdemoserver;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class ContractdemoserverApplication {
public static void main(String[] args) {
SpringApplication.run(ContractdemoserverApplication.class, args);
}
}
ServerDefaultController:
package com.example.contractdemoserver;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
public class ServerDefaultController {
public static final String controllerName = "test";
public static final String controllerPath = "/" + controllerName;
#RequestMapping(value = controllerPath, headers={"application/json"})
#ResponseBody
public TestObject get(){
return new TestObject(1001, new String[0]);
}
}
TestObject:
package com.example.contractdemoserver;
public class TestObject {
private int id;
private String[] cards;
public TestObject(){}
public TestObject(int id, String[] cards){
setId(id);
setCards(cards);
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String[] getCards() {
return cards;
}
public void setCards(String[] cards) {
this.cards = cards;
}
}
ContractdemoserverBase:
package com.example.contractdemoserver;
import io.restassured.module.mockmvc.RestAssuredMockMvc;
import org.junit.Before;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#SpringBootTest
public abstract class ContractdemoserverBase {
#Before
public void setup() {
RestAssuredMockMvc.standaloneSetup(new ServerDefaultController());
}
}
shouldGetProfile.groovy:
package contracts.contractdemoserver
import org.springframework.cloud.contract.spec.Contract
Contract.make {
description("""
Represents a successful scenario of getting a response from the /test endpoint.
```
given:
nothing
when:
a request for a Test is made
then:
returns a test object with id 1001 and no cards
```
""")
request {
method 'GET'
url '/test'
headers {
contentType(applicationJson())
}
}
response {
status 200
body("""
{
"id":1001,
"cards":[]
}
""")
headers {
contentType(applicationJson())
}
}
}

Any suggestions would be greatly appreciated.

Answer 1

The method #RequestMapping(value = controllerPath, headers={"application/json"}) is missing/requires the property produces = "application/json" in order for Contract testing to work. Classic Spring feedback.
