JUnit test for post Rest WS using rest-assured - post

Question

I am writing junit for post using rest-assured, and while executing
My Test Class:
public class PolicyResourceTest {
private static MockRESTServer server;
#BeforeClass
public static void setUpBeforeClass() throws Exception {
server = new MockRESTServer(8080, new PolicyResource());
server.start();
}
#AfterClass
public static void tearDownAfterClass() throws Exception {
server.stop();
}
#Test
public final void testCreatePolicy() {
Policy policy=new Policy();
policy.setName("policy123");
RestAssured.with()
.contentType("application/json")
.accept("application/json")
.body(policy)
.post("/create")
.then()
.assertThat()
.statusCode(200);
}
My Resource Class:
#Path("/")
public class PolicyResource {
#POST
#Path("/create")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response test( Policy messageBody) {
System.out.println("policy: "+messageBody);
return Response.ok().status(200).build();
}
}
I am getting below exception:
org.apache.http.NoHttpResponseException: localhost:8080 failed to respond

#Anju Singh, Make sure your back end is working properly.
I tried the request on my local as we as on the mock api and was successfully able to test for Objects as well. The exception you received org.apache.http.NoHttpResponseException: localhost:8080 failed to respond is from the Server. There is no issue from RestAssured or JUnit to resolve.
#Test(enabled=true)
public void sampleTester() {
EnrollEmail email = new EnrollEmail();
email.setEmailAddress("sample#domain.com");
RestAssured.given().contentType(ContentType.JSON).body(email).when().post("https://jsonplaceholder.typicode.com/posts").then()
.assertThat()
.statusCode(201);
}
#Test(enabled=true)
public void sampleTester2() {
EnrollEmail email = new EnrollEmail();
email.setEmailAddress("sample#domain.com");
RestAssured.given().contentType(ContentType.JSON).body(email).when().post("http://localhost:8089/posts").then()
.assertThat()
.statusCode(201);
}
