I am using okhttp to mock my http responses during my tests.
//Create a mock server
mockWebServer.start(8080)
mockWebServer.enqueue(MockResponse().setBody("").setResponseCode(HttpURLConnection.HTTP_OK))
However, this responds to every path as OK.
How do I mock a specific url instead of all of them?
Using Dispatcher
Dispatcher dispatcher = new Dispatcher() {
#Override
public MockResponse dispatch(RecordedRequest request) {
switch (request.getPath()) {
case "/get":
return new MockResponse().setResponseCode(200).setBody("test");
}
return new MockResponse().setResponseCode(404);
}
};
mockBackEnd.setDispatcher(dispatcher);
Above can be written inside your test method. You can have a bunch of URLs conditions there.
The mockwebserver can be started once like:
public static MockWebServer mockBackEnd;
#BeforeAll
static void setUp() throws IOException {
mockBackEnd = new MockWebServer();
mockBackEnd.start();
}
#AfterAll
static void tearDown() throws IOException {
mockBackEnd.shutdown();
}
Use #DynamicPropertySource to change any property with mockserver host/port.

In my camel context I have a route defined as follows:
from("direct:getPets")
.routeId("getPets")
.to("http://localhost:4321/pets")
The route works well and makes a call to the server. I'd like to test this route and check the headers but I have issues.
This is a spring project so my test class looks as follows:
#RunWith(CamelSpringBootRunner.class)
#DirtiesContext(classMode = DirtiesContext.ClassMode.After_EACH_TEST_METHO)
#UseAdviceWith
public class TestRestEndpoint {
#Autowired
private CamelContext camelContext;
#Produce(uri = "direct:getPets")
private ProducerTemplate callServer;
#EndpointInject(uri = "mock:catchTestEndpoint")
#Test
public void should_return_json() throws Exception {
camelContext.getRouteDefinitions("getPets").adviceWith(camelContext, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
weaveAddLast().to("mock:catchTestEndpoint");
}
});
camelContext.start();
callServer.sendBody("");
mockEndpoint.expectedMessageCount(1);
mockEndpoint.assertIsSatisfied();
}
}
The exchange fails and returns a null pointer.
org.apache.camel.CamelExecutionException: Exception occurred during execution on the exchange: Exchange[ID-PVJ-DEV97-03-2-1600178584697-0-1]
Sounds like your appended Mock is null.
If the code in your question really is your code, this is probably because you have a typo in your endpoint URI.
Notice the extra t between "catch" and "Test" in mock:catchtTestEndpoint
I defined a Spring Boot App as a Verticle as follows:
#SpringBootApplication
public class SpringAppVerticle extends AbstractVerticle {
private Vertx myVertx;
#Override
public void start() {
SpringApplication.run(SpringAppVerticle.class);
System.out.println("SpringAppVerticle started!");
this.myVertx = vertx;
}
#RestController
#RequestMapping(value = "/api/hello")
public class RequestController {
#RequestMapping(method = RequestMethod.GET, produces = "application/json")
public void getEcho() {
JsonObject message = new JsonObject()
.put("text", "Hello world!");
myVertx.eventBus().send(EchoServiceVerticle.ADDRESS, message, reply -> {
JsonObject replyBody = (JsonObject) reply.result().body();
System.out.println(replyBody.encodePrettily());
});
}
}
}
I have a second non-Spring Verticle that is basically a echo service:
public class EchoServiceVerticle extends AbstractVerticle {
public static final String ADDRESS = "echo-service";
#Override
public void start() {
System.out.println("EchoServiceVerticle started!");
vertx.eventBus().consumer(EchoServiceVerticle.ADDRESS, message -> {
System.out.println("message received");
JsonObject messageBody = (JsonObject) message.body();
messageBody.put("passedThrough", "echo-service");
message.reply(messageBody);
});
}
}
The problem is that I get a nullpointer at line myVertx.eventbus().send in SpringAppVerticle class as the myVertx variable is null.
How do I properly instantiate a Vertx variable in a Spring context in order that I can exchange message between my both verticles?
My project can be found here: https://github.com/r-winkler/vertx-spring
The reason of the exception is the following:
SpringAppVerticle bean that is created during spring init is another object than starts the spring boot application. So you have two objects, one that has start() method invoked and another one that doesn't. Second one actually handles requests. So what you need is to register verticles as spring beans.
For samples of vertx/spring interoperability please refer to vertx examples repo.
P.S. I've created a pull request to your repo to make your example work.
I have a Spring Boot application and want to cover my REST controllers by integration test.
Here is my controller:
#RestController
#RequestMapping("/tools/port-scan")
public class PortScanController {
private final PortScanService service;
public PortScanController(final PortScanService portScanService) {
service = portScanService;
}
#GetMapping("")
public final PortScanInfo getInfo(
#RequestParam("address") final String address,
#RequestParam(name = "port") final int port)
throws InetAddressException, IOException {
return service.scanPort(address, port);
}
}
In one of test cases I want to test that endpoint throws an exception in some circumstances. Here is my test class:
#RunWith(SpringRunner.class)
#WebMvcTest(PortScanController.class)
public class PortScanControllerIT {
#Autowired
private MockMvc mvc;
private static final String PORT_SCAN_URL = "/tools/port-scan";
#Test
public void testLocalAddress() throws Exception {
mvc.perform(get(PORT_SCAN_URL).param("address", "192.168.1.100").param("port", "53")).andExpect(status().isInternalServerError());
}
}
What is the best way to do that? Current implementation doesn't handle InetAddressException which is thrown from PortScanController.getInfo() and when I start test, I receive and error:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.handytools.webapi.exceptions.InetAddressException: Site local IP is not supported
It is not possible to specify expected exception in #Test annotation since original InetAddressException is wrapped with NestedServletException.
Spring Boot Test package comes with AssertJ that has very convenient way of verifying thrown exceptions.
To verify cause:
#Test
public void shouldThrowException() {
assertThatThrownBy(() -> methodThrowingException()).hasCause(InetAddressException .class);
}
There are also few more methods that you may be interested in. I suggest having a look in docs.
In order to test the wrapped exception (i.e., InetAddressException), you can create a JUnit Rule using ExpectedException class and then set the expectMessage() (received from NestedServletException's getMessage(), which contains the actual cause), you can refer the below code for the same:
#Rule
public ExpectedException inetAddressExceptionRule = ExpectedException.none();
#Test
public void testLocalAddress() {
//Set the message exactly as returned by NestedServletException
inetAddressExceptionRule.expectMessage("Request processing failed; nested exception is com.handytools.webapi.exceptions.InetAddressException: Site local IP is not supported");
//or you can check below for actual cause
inetAddressExceptionRule.expectCause(org.hamcrest.Matchers.any(InetAddressException.class))
//code for throwing InetAddressException here (wrapped by Spring's NestedServletException)
}
You can refer the ExpectedException API here:
http://junit.org/junit4/javadoc/4.12/org/junit/rules/ExpectedException.html
You could define an exception handler
#ExceptionHandler(InetAddressException.class)
#ResponseStatus(HttpStatus.BAD_REQUEST)
#ResponseBody
public Response handledInvalidAddressException(InetAddressException e)
{
log e
return getValidationErrorResponse(e);
}
and then in your test you could do
mvc.perform(get(PORT_SCAN_URL)
.param("address", "192.168.1.100")
.param("port", "53"))
.andExpect(status().isBadRequest())
.andExpect(jsonPath("$.response").exists())
.andExpect(jsonPath("$.response.code", is(400)))
.andExpect(jsonPath("$.response.errors[0].message", is("Site local IP is not supported")));
I had the same issue and i fix it with org.assertj.core.api.Assertions.assertThatExceptionOfType :
#Test
public void shouldThrowInetAddressException() {
assertThatExceptionOfType(InetAddressException.class)
.isThrownBy(() -> get(PORT_SCAN_URL).param("address", "192.168.1.100").param("port", "53"));
}
I hope it's help you !
I am trying to call a RESTfull web service resource, this resource is provided by a third party, the resource is exposed with OPTIONS http verb.
To integrate with the service, I should send a request with a specific body, which identities by a provider, but when I did that I got a bad request. After that I trace my code then I recognized that the body of the request is ignored by rest template based on the below code:
if ("POST".equals(httpMethod) || "PUT".equals(httpMethod) ||
"PATCH".equals(httpMethod) || "DELETE".equals(httpMethod)) {
connection.setDoOutput(true);
}
else {
connection.setDoOutput(false);
}
my question, is there a standard way to override this behavior or I should use another tool?
The code you've pasted is from
SimpleClientHttpRequestFactory.prepareConnection(HttpURLConnection connection, String httpMethod)
I know because I've debugged that code few hours ago.
I had to do a HTTP GET with body using restTemplate. So I've extend SimpleClientHttpRequestFactory, override prepareConnection and create a new RestTemplate using the new factory.
public class SimpleClientHttpRequestWithGetBodyFactory extends SimpleClientHttpRequestFactory {
#Override
protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
super.prepareConnection(connection, httpMethod);
if ("GET".equals(httpMethod)) {
connection.setDoOutput(true);
}
}
}
Create a new RestTemplate based on this factory
new RestTemplate(new SimpleClientHttpRequestWithGetBodyFactory());
A test to prove the solution is working using spring boot (#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT))
public class TestRestTemplateTests extends AbstractIntegrationTests {
#Test
public void testMethod() {
RestTemplate restTemplate = new RestTemplate(new SimpleClientHttpRequestWithBodyForGetFactory());
HttpEntity<String> requestEntity = new HttpEntity<>("expected body");
ResponseEntity<String> responseEntity = restTemplate.exchange("http://localhost:18181/test", HttpMethod.GET, requestEntity, String.class);
assertThat(responseEntity.getBody()).isEqualTo(requestEntity.getBody());
}
#Controller("/test")
static class TestController {
#RequestMapping
public #ResponseBody String testMethod(HttpServletRequest request) throws IOException {
return request.getReader().readLine();
}
}
}
I have a resource endpoint that injects a #PathParam into constructor, i.e., different instance per #PathParam value. It all works fine in Jetty. But now I'm trying to write unit tests using Jersey Test Framework, and it seems that the test framework only supports one registered endpoint per type.
So if I do something like this:
#Path("/users")
public class MyResource {
public MyResource(#PathParam("userId") int userId) {
}
#Path("{userId}")
public String get() {
}
}
public class MyTest extends JerseyTestNg.ContainerPerClassTest {
#Override
protected Application configure() {
return new ResourceConfig()
.register(new MyResource(1))
.register(new MyResource(2));
}
#Test
public void test2() {
target("/users/1").request().get();
}
#Test
public void test2() {
target("/users/2").request().get();
}
}
I see that both test1 and test2 are invoking the instance of MyResource(1). Is this expected? Is there a solution to invoke the correct instance?
You should register the resource as a class. Jersey will create it for you. And handle all the injections.
"The example I posted is dumbed down. In reality, my resource constructor has another injected object that I need to mock. So how would I specify a mocked object parameter for the constructor?"
You can do something like
#Mock
private Service service;
#Override
public ResourceConfig configure() {
MockitoAnnotations.initMocks(this);
return new ResourceConfig()
.register(MyResource.class)
.register(new AbstractBinder() {
#Override
protected configure() {
bind(service).to(Service.class);
}
});
}
#Test
public void test() {
when(service.getSomething()).thenReturn("Something");
// test
}
Assuming you are already using the built in HK2 DI, and have an #Inject annotation on the constructor of your resource class, this should work. In the AbstractBinder we are making the mock object injectable. So now Jersey can inject it into your resource.
