Unit testing Placeholder defaultValue in #RequestParam - unit-testing

I'm trying to test my controller that has a handler with a RequestParam configured with a default value pointed to a placeholder:
#Controller
public class AgeController {
#GetMapping("/age")
public String home(#RequestParam(name="current", defaultValue="${default.age}") Integer age) {
return "age"+age;
}
}
This works fine when I'm testing through my browser but when I use the following test case, it throws an exception:
Test Case:
public class AgeControllerTest {
AgeController controller
MockMvc mockMvc;
#Before
public void setUp() {
ageController = new AgeController();
mockMvc = MockMvcBuilders.standaloneSetup(controller).addPlaceholderValue("default.age", "10").build();
}
#Test
public void test() {
mockMvc.perform(get("/age")).andExpect(status().isOk());
}
}
Exception:

Junit java.lang.IllegalArgumentException: Could not resolve placeholder 'cors.origin.value' in value "${cors.origin.value}"

It is actually resolved but I will leave here solution if anyone will face the same issue. You have to configure placeholder manually like:
public EventControllerTest() {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(eventController)
.addPlaceholderValue("cors.origin.value", "http://localhost:4200")
.build();
}
I am trying to perform simple unit test of some method from controller but I am facing an issue:
java.lang.IllegalArgumentException: Could not resolve placeholder 'cors.origin.value' in value "${cors.origin.value}"
Why is that happen? it is only simple unit test so I do not have to setup whole context for this right?
My code:
request I am calling is API_V1_EVENTS_FIND_BY_GENRE:
public class TestApiUrlStrings {
public static final String API_V1_EVENTS = "api/v1/events";
public static final String API_V1_EVENTS_FIND_BY_GENRE = API_V1_EVENTS + "/Dance?page=0";
}
Unit Test
public class EventControllerTest {
#Mock
EventService eventService;
#InjectMocks
EventController eventController;
MockMvc mockMvc;
public EventControllerTest() {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(eventController)
.build();
}
#Test
public void findByGenre() throws Exception {
EventsDTO expected = EventsDTOdatasource.getEventsDTO();
when(eventService.findByGenre(anyString(),anyInt())).thenReturn(expected);
mockMvc.perform(get(TestApiUrlStrings.API_V1_EVENTS_FIND_BY_GENRE)
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(jsonPath("$.events", hasSize(3)));
}
}
And controller
#Slf4j
#CrossOrigin(value = "${cors.origin.value}")
#RestController
#RequestMapping(EventController.API_V1_EVENTS)
public class EventController {
public static final String API_V1_EVENTS = "api/v1/events";
private final EventService eventService;
public EventController(EventService eventService) {
this.eventService = eventService;
}
#GetMapping("/{musicGenre}")
#ResponseStatus(HttpStatus.OK)
public EventsDTO findByGenre(#PathVariable String musicGenre,
#RequestParam(value = "page", defaultValue = "0") Integer pageNum) {
return eventService.findByGenre(musicGenre, pageNum);
}
#PutMapping
#ResponseStatus(HttpStatus.CREATED)
public EventsDTO saveAll(#RequestBody EventsDTO eventsDTO) {
return this.eventService.saveAll(eventsDTO);
}
}
Why exception is pointing to CORS value where I do not even need it here?
How to resolve this? There is not much about such exception anywhere.

Mockmvc Controller throws NullPointerException

maybe someone can tell me why I always get NullPointerException when testing my Controller.
It tells me that the NullPointerException happens here:
mvc.perform(get("/passwordaenderung"))
Here is my code:
public class LagerstandortControllerTest {
#InjectMocks
private PasswordChange passwordChange;
// add #Mock annotated members for all dependencies used by the controller here
private MockMvc mvc;
// add your tests here using mvc.perform()
#Test
public void getHealthStatus() throws Exception {
mvc.perform(get("/passwordaenderung"))
.andExpect(status().isOk())
.andExpect(jsonPath("$.status", is("OK")));
}
#Before
public void createControllerWithMocks() {
MockitoAnnotations.initMocks(this);
MockMvcBuilders.standaloneSetup(new PasswordChange()).build();
}
}
What I want to achieve is to test my controller without loading the whole ApplicationContext.
I had to adapt it in order to avoid a NullPointerException:
Introduced a new class:
public class StandaloneMvcTestViewResolver extends InternalResourceViewResolver {
public StandaloneMvcTestViewResolver() {
super();
}
#Override
protected AbstractUrlBasedView buildView(final String viewName) throws Exception {
final InternalResourceView view = (InternalResourceView) super.buildView(viewName);
// prevent checking for circular view paths
view.setPreventDispatchLoop(false);
return view;
}
}
And in my setup method:
#Before
public void setUp() {
final MainController controller = new MainController();
mvc = MockMvcBuilders.standaloneSetup(controller)
.setViewResolvers(new StandaloneMvcTestViewResolver())
.build();
}
The only problem is now that I get a 404 error.
Do I have to put my index.html in
/src/test/resources
too?

getExchange from mockEndPoint in a unit-test class for Camel Route Not Behaving As Expected

I want to getExchanges from a mockEndPoint in a unit-test class for Camel Route but it doesn't work.
Here is my unit test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("classpath:camel-unit-test.xml")
public class ImportDatabaseRouteTest extends CamelTestSupport {
#Value("${sql.importDatabase}")
String oldEndPoint;
#Autowired
private ImportDatabaseRoute importDatabaseRoute;
#Autowired
private DriverManagerDataSource dataSource;
#Override
protected RouteBuilder createRouteBuilder() throws Exception {
return importDatabaseRoute;
}
#Before
public void mockEndpoints() throws Exception {
AdviceWithRouteBuilder adviceTest = new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
interceptSendToEndpoint(oldEndPoint)
.skipSendToOriginalEndpoint()
.to("mock:catchCSVList");
}
};
context.getRouteDefinitions().get(0).adviceWith(context, adviceTest);
}
#Override
public boolean isUseAdviceWith() {
return true;
}
#Override
protected JndiRegistry createRegistry() throws Exception {
JndiRegistry jndi = super.createRegistry();
//use jndi.bind to bind your beans
jndi.bind("dataSource", dataSource);
return jndi;
}
#Test
public void testTheImportRoute() throws Exception {
MockEndpoint mockEndPointTest = getMockEndpoint("mock:catchCSVList");
context.start();
List<List<String>> test = (List<List<String>>) mockEndPointTest.getExchanges().get(0).getIn().getBody();
assertEquals("4227",test.get(1).get(0));
assertEquals("370",test.get(1).get(1));
assertEquals("",test.get(1).get(2));
mockEndPointTest.expectedMessageCount(1);
mockEndPointTest.assertIsSatisfied();
context.stop();
}
}
And here are the results:
java.lang.ArrayIndexOutOfBoundsException: 0
at java.util.concurrent.CopyOnWriteArrayList.get(CopyOnWriteArrayList.java:387)
Please help me to fix it. Thank you so much.
You have to assert the mock before you get the exchanges. As those exchanges are the actual exchange that arrived at the mock. So its expectations has to be meet first, which says 1 message should arrive. And if that is success, then you can get that exchange via index 0, and you will not get an IndexOutOfBoundsException
MockEndpoint mockEndPointTest = getMockEndpoint("mock:catchCSVList");
context.start();
// set expectations on mock here
mockEndPointTest.expectedMessageCount(1);
mockEndPointTest.assertIsSatisfied();
// okay now we can get the exchange's from the mock
List<List<String>> test = (List<List<String>>) mockEndPointTest.getExchanges().get(0).getIn().getBody();
assertEquals("4227",test.get(1).get(0));
assertEquals("370",test.get(1).get(1));
assertEquals("",test.get(1).get(2));
context.stop();

Test individual Spring Batch Tasklet step with parameters

I've implemented a simple job with 2 tasklets. I want to test the second tasklet by passing parameters.
I've read the Spring batch documentation and below my test:
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles({"test"})
#TestExecutionListeners( { DependencyInjectionTestExecutionListener.class,
StepScopeTestExecutionListener.class })
public class EtudeBatchApplicationTests {
#Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
public StepExecution getStepExecution() {
StepExecution execution = MetaDataInstanceFactory.createStepExecution();
execution.getJobExecution().getExecutionContext().putString("myValue", "foo,bar,spam");
return execution;
}
#Test
public void contextLoads() {
JobExecution jobExecution = jobLauncherTestUtils.launchStep("insertIncludedSiretsStep");
}
}
My problem is in my tasklet, the myValue is always null.
Below, the code of the tasklet:
#Component
#StepScope
#Slf4j
public class InsertIncludedSiretsTask implements Tasklet {
#Override
public RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {
Object myValue = chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext().get("myValue");
log.info("INSERTINCLUDEDSIRETSTASK runnning");
Thread.sleep(3000);
return RepeatStatus.FINISHED;
}
}
You can mock the ChunkContext following this example :
http://www.javased.com/index.php?source_dir=spring-insight-plugins/collection-plugins/spring-batch/src/test/java/com/springsource/insight/plugin/springbatch/TaskletCollectionAspectTest.java
Here is my code :
public ChunkContext createChunkContext() {
StepExecution stepExecution=Mockito.mock(StepExecution.class);
StepContext stepContext=Mockito.mock(StepContext.class);
ChunkContext chunkContext=Mockito.mock(ChunkContext.class);
JobExecution jobExecution= createJobExecution();
Mockito.when(chunkContext.getStepContext()).thenReturn(stepContext);
Mockito.when(stepContext.getStepExecution()).thenReturn(stepExecution);
Mockito.when(stepExecution.getJobExecution()).thenReturn(jobExecution);
return chunkContext;
}
public JobExecution createJobExecution() {
JobExecution execution = MetaDataInstanceFactory.createJobExecution();
execution.getExecutionContext().putString("myValue", "foo,bar,spam");
return execution;
}
#Test
public void testSendEmail() throws Exception {
StepContribution contribution= Mockito.mock(StepContribution.class);
ChunkContext chunkContext= createChunkContext();
sendReportTasklet.execute(contribution, chunkContext );
}
Based on Melkior answer which helped me a lot I simplify the test:
public class MyTaskletTest {
private static final String MY_JOB_PARAM = "my.job.param";
#Mock
private StepContribution stepContribution;
#Mock
private StepExecution stepExecution;
#Mock
private StepContext stepContext;
#Mock
private ChunkContext chunkContext;
private MyTasklet tasklet;
#Before
public void setupTest() {
when(chunkContext.getStepContext()).thenReturn(stepContext);
when(stepContext.getStepExecution()).thenReturn(stepExecution);
}
#Override
public void init() {
tasklet = new MyTasklet();
}
#Test
public void should_test_my_tasklet() throws Exception {
when(stepExecution.getJobParameters()).thenReturn(defaultJobParameters("myParam"));
tasklet.execute(stepContribution, chunkContext);
}
private JobParameters defaultJobParameters(String myParam) {
JobParametersBuilder paramsBuilder = new JobParametersBuilder();
paramsBuilder.addString(MY_JOB_PARAM, myParam);
return paramsBuilder.toJobParameters();
}
}

JUnit Tests for Liferay MVCPortlet using PowerMock

Im trying to make JUnit Test using PowerMock, but I have one problem. Here is my code:
public class MyGreeting extends MVCPortlet {
public static final String GREETING="greeting";
private static final String DEFAULT_GREETING="MY DEFAULT GREETING MESSAGE";
private static final Log _log = LogFactoryUtil.getLog(MyGreeting.class.getName());
#Override
public void render(RenderRequest req,RenderResponse res)
throws IOException, PortletException {
PortletPreferences prefs = req.getPreferences();
req.setAttribute(GREETING, prefs.getValue(GREETING, DEFAULT_GREETING));
super.render(req,res);
}
And I need to make JUnit test. I created another test package, new MyGreetingTest.java file, and come up to this code:
public class MyGreetingTest extends Mockito{
#BeforeClass
public static void setUpBeforeClass() throws Exception {
}
#AfterClass
public static void tearDownAfterClass() throws Exception {
}
private MyGreeting portlet;
#Before
public void setUp() throws Exception {
portlet = new MyGreeting();
}
#After
public void tearDown() throws Exception {
}
#Mock
public RenderRequest request = mock(RenderRequest.class);
#Mock
PortletPreferences preferences = mock(PortletPreferences.class);
#Test
public final void renderTest() throws IOException, PortletException {
when(request.getPreferences()).thenReturn(preferences);
when(preferences.getValue(MyGreeting.GREETING, null)).thenReturn(value);
portlet.render(request, null);
String result = request.getAttribute(MyGreeting.GREETING).toString();
assertEquals(result, value);
}
But I have NullPointerException, because we can't apply getAttribute method to mock-request. Could you please tell me how to solve this problem? How can I test method with getAttribute method using Mockito?
I think you need to mock your method
Stock stock = mock(Stock.class);
when(stock.getPrice()).thenReturn(100.00); // Mock implementation
when(stock.getValue()).thenCallRealMethod(); // Real implementation
