Looks like the problem is inside Driver_Setup class - getWebDriver returns null since you have not called setWebDriver() to set the instance value.

I have an issue running Controller Tests with CompletableFeature,
I create a StockController!
#Component
public class StockController implements StockResource {
private UseCaseExecutor useCaseExecutor;
private GetAllStocksUseCase getAllStocksUseCase;
#Autowired
public StockController(UseCaseExecutor useCaseExecutor,
GetAllStocksUseCase getAllStocksUseCase) {
this.useCaseExecutor = useCaseExecutor;
this.getAllStocksUseCase = getAllStocksUseCase;
}
#Override
public CompletableFuture<List<StockResponse>> getAllStocks(
#RequestParam(value="materialNumber", required=false) String materialNumber,
#RequestParam(value="storageLocation", required=false) String storageLocation,
#RequestParam(value="plant", required=false) String plant) {
return useCaseExecutor.execute(
getAllStocksUseCase,
GetAllStocksInputMapper.map(
materialNumber,
storageLocation,
plant
),
(outputValues) -> StockResponse.from(outputValues.getStockList()));
}
And create a StockControllerTest
#RunWith(SpringRunner.class)
#WebMvcTest(value = StockController.class, secure = false)
public class StockControllerTest {
#MockBean
private GetAllStocksUseCase getAllStocksUseCase;
#SpyBean
private UseCaseExecutorImpl useCaseExecutor;
#Autowired
private MockMvc mockMvc;
#Configuration
#ComponentScan(basePackages = {"com.example.presenter.rest.api.stock"})
static class Config {
}
#Test
public void deliveryOrderReturnsOk() throws Exception {
Stock stock = TestEntityGenerator.randomStock();
GetAllStocksUseCase.InputValues input = GetAllStocksInputMapper.map(
stock.getMaterialNumber(),
stock.getStorageLocation(),
stock.getPlant());
GetAllStocksUseCase.OutputValues output = new GetAllStocksUseCase.OutputValues(Collections.singletonList(stock));
doReturn(output)
.when(getAllStocksUseCase)
.execute(input);
final String request =
"/api/stocks?materialNumber=" +
stock.getMaterialNumber() + "&plant=" + stock.getPlant() + "&storageLocation=" + stock.getStorageLocation();
RequestBuilder payload = asyncGetRequest(request);
mockMvc.perform(payload)
.andExpect(status().isOk())

}
protected RequestBuilder asyncGetRequest(String url) throws Exception {
return asyncDispatch(mockMvc.perform(get(url))
.andExpect(request().asyncStarted())
.andReturn());
}
}
And have a UseCaseExecutor to run a useCase with some input to generate some output.
GetAllStocksUseCase
#Service
public class GetAllStocksUseCase extends UseCase<GetAllStocksUseCase.InputValues, GetAllStocksUseCase.OutputValues> {
private StockDAO stockDAO;
#Autowired

#Override
public OutputValues execute(InputValues input) {

}
public static class InputValues implements UseCase.InputValues {
private Stock stock;
public InputValues(Stock stock) {
this.stock = stock;
}
public Stock getStock() {
return stock;
}
}
public static class OutputValues implements UseCase.OutputValues {
List<Stock> stockList;
public OutputValues(List<Stock> stockList) {
this.stockList = stockList;
}
public List<Stock> getStockList() {
return stockList;
}
}
}
UseCaseExecutor
#Service
public class UseCaseExecutorImpl implements UseCaseExecutor {
#Override
public <RX, I extends UseCase.InputValues, O extends UseCase.OutputValues> CompletableFuture<RX> execute(

return CompletableFuture
.supplyAsync(() -> input)
.thenApplyAsync(useCase::execute)
.thenApplyAsync(outputMapper);
}
}
When I run the test it gives a NullPointException on OutputValues

Can anyone help me with this problem? It seems that it does not run the execute of useCase before the outputMapper so the OutputValues are null
I am new to Mockito and i am facing a issue due to a property is not loading in from appication.properties file.
Problem statement: I am trying to mock a method which uses a property from the application.properties file. When the control arrives at the line to load property value it shows null and because of this mockito throws java.lang.NullPointerException.
What i am looking for is how to load the property from application.properties file when mocking a method.
Here i am trying to load global variable partsListGlobal .Please help me how to achieve this.?
Here is my below code snippet.
#Service
public class ClimoDiagnosticReportServImpl implements ClimoDiagnosticReportService {
#Value("${PARTS_LIST}")
private String partsListGlobal;
#Override
public boolean getSomeResult() {
String[] partsListLocal = getPartsList();
List<String> partsList = Arrays.asList(partsListGlobal);
if (partsList.contains("PART_X1"))
return true;
else
return false;
}
public String[] getPartsList() {
return partsListGlobal.split(",");// Here is the error occuring due to partsListGlobal is not loading the value from application.properties file.
}
}
#RunWith(MockitoJUnitRunner.class)
public class ClimoDiagnosticReportServImplTest {
#InjectMocks
private ClimoDiagnosticReportServImpl serviceReference1;
#Mock
private ClimoDiagnosticReportServImpl serviceReference12;
#Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
#Test
public void getSomeResultTest() {
boolean result1 = false;
String[] strArray = new String[2];
strArray[0] = "P1";
strArray[1] = "P2";
Mockito.when(serviceReference12.getPartsList()).thenReturn(strArray);
boolean result2 = serviceReference1.getSomeResult();
Assert.assertEquals(result1,result2);
}
}

Thanks everyone in advance.
You don't have any dependency to mock in the service. Mockito is thus completely unnecessary. What you need to do is to set the private String field, that is populated by Spring in your application using reflection.
Just follow the best practice os using cnstructor injection instead of field injection, and that will make your code testable (that's one of the reasons why it's a best practice):
#Service
public class ClimoDiagnosticReportServImpl implements ClimoDiagnosticReportService {
private String partsListGlobal;
public ClimoDiagnosticReportServImpl(#Value("${PARTS_LIST}") String partsListGlobal) {
this.partsListGlobal = partsListGlobal;
}
// ...
}
Your test now can be reduced to
public class ClimoDiagnosticReportServImplTest {
#Test
public void shouldReturnTrueIfPropertyContainsPartX1() {
ClimoDiagnosticReportServImpl service = new ClimoDiagnosticReportServImpl("a,b,c,PART_X1,d");
assertTrue(service.getSomeResult());
}
#Test
public void shouldReturnFalseIfPropertyDoesNotContainPartX1() {
ClimoDiagnosticReportServImpl service = new ClimoDiagnosticReportServImpl("a,b,c,d");
assertFalse(service.getSomeResult());
}
}
I'm trying to test a method in service class which uses ModelMapper to convert entity to dto, but I'm getting NullPointerException at this line mapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT); in the service class.

You shouldn't reassign your mocked ModelMapper in setup method. Remove this method
And I can't find in your code mock definition for mapper.getConfiguration()
when(mapper.getConfiguration()).thenReturn(...)
You should tell it to mockito.
I want to test a XML Web Services (JAX-WS) deployed on a JBoss 7 and created with maven on an Eclipse so I created a Junit test to do so.
Here my Junit test

public void testListPerson() throws Exception {
IberiaWSBindingStub stub = new IberiaWSBindingStub(new URL("http://iberia.test.buildizz.com/IberiaWSPort"),null);

static org.apache.axis.description.OperationDesc [] _operations;
static {
_operations = new org.apache.axis.description.OperationDesc[7];
_initOperationDesc1();
}
..
}
and

I use spring framework 4 and have class that has his line :
String link = ServletUriComponentsBuilder.fromCurrentContextPath().path("/admin/menu/edit/"+id).build().toUriString();
Class perfectly run in on server but when I want to unit test it and create the class and call method that use above could got a error:
java.lang.IllegalStateException: Could not find current request via RequestContextHolder

my class:
#Component
public class HiararchyUtils {
public String getHForTableMenu(List<? extends Hierarchically> menus, Integer parentId) {
seperateParentsIntoAssoc(menus);
return createTableTrMenu(parentId, 0);
}
public String createTableTrMenu(Integer parent, Integer level) {
// some code
String link = ServletUriComponentsBuilder.fromCurrentContextPath().path("/admin/menu/edit/"+items.get(itemId).getId()).build().toUriString();
// some code
}}
test class :
#RunWith(MockitoJUnitRunner.class)
public class HiararchyUtilsTest {
private HiararchyUtils hiararchyUtils;
#Before
public void setup() {
hiararchyUtils = new HiararchyUtils();
}
#Test
public void getHForTableMenu_() {
String trs = hiararchyUtils.getHForTableMenu(menus);
}
}
what should I do?
It may be as easy as adding a MockHttpServletRequest in order to provide the needed RequestContextHolder and context path.
As a class variable, add
private MockHttpServletRequest mockRequest;
Then, when setting up your test(s), try:
#Before
mockRequest = new MockHttpServletRequest();
mockRequest.setContextPath("/your-app-context");
ServletRequestAttributes attrs = new ServletRequestAttributes(mockRequest);
RequestContextHolder.setRequestAttributes(attrs);
That should address that error.
