How to test Camel using ScalaTest - scala

I want to unit test Camel code using ScalaTest and the FunSpec test style.
To do so, I need to extend from both FunSpec and CamelTestSupport. However, both these are classes and at least one needs to be a trait in order to do this in Scala. For example, this does not work:
class MySpec extends FunSpec with CamelTestSupport {}
Note: It appears that many online references to FunSpec suggest it is a trait, but it is a class in scalatest_2.11-3.0.0-M15.
How can I use ScalaTest FunSpec to test Camel?
The same test written using JUnit would look as follows:
public class DataLakeEventListenerRouteIT extends CamelTestSupport {
#Autowired
private MyRouteBuilder myRouteBuilder;
private MockEndpoint myEndpointMock;
#Override
public boolean isUseAdviceWith() {
return true;
}
#Override
protected JndiRegistry createRegistry() throws Exception {
JndiRegistry registry = super.createRegistry();
//do some required bindings here
return registry;
}
#Before
public void startup() throws Exception {
AdviceWithRouteBuilder mock = new AdviceWithRouteBuilder() {
public void configure() throws Exception {
mockEndpointsAndSkip(myRouteBuilder.MY_ROUTE_URI);
}
};
context.addRoutes(myRouteBuilder);
context.getRouteDefinition(myRouteBuilder.MY_ROUTE_ID)
.adviceWith(context, mock);
myEndpointMock = getMockEndpoint(
"mock:" + myRouteBuilder.MY_ROUTE_URI);
}
#Test
public void timerRouteShouldSendMessage() throws Exception {
// Arrange
context.start();
myEndpointMock.expectedMessageCount(1);
myEndpointMock.assertIsSatisfied();
context.stop();
}
}

Well, it turns out to straightforward. ScalaTest offers a trait equivalent of FunSpec called FunSpecLike. Declare the test like so:
class StoreSVSFileRouteSpec extends CamelTestSupport with FunSpecLike {}

Spring 4, Mockito 2, Junit 4 in Eclipse Oxygen - DAO not mocked

I have an annotated Junit 4 test using JDK 1.8 running in Eclipse. I'm using Mockito to mock the DAO in the service class under test. The runner in the abstract class extends SpringJUnit4ClassRunner. When I run the test, the unimplemented method in the concrete DAO class is called, instead of the mocked method. I've searched and searched, and can't seem to find a solution. What am I doing wrong?
SOLVED - I changed the #InjectMocks #Autowired IOrganizationsService organizationsService; to remove the interface and autowiring, #InjectMocks OrganizationsService organizationsService; fixed below, and the DAO gets mocked. Now the question, why wasn't the DAO in the declaration using the interface mocked?
#ContextConfiguration(classes = { AppXmlConfigTest.class, AppConfig.class }, inheritLocations = false)
#WebAppConfiguration
public class MockOrganizationsServiceTest extends AbstractCoreJunit4Test {
public MockOrganizationsServiceTest() {
super();
}
#InjectMocks
OrganizationsService organizationsService;
#Mock
IOrganizationsDao organizationsDao;
#Before
public void setupMock() {
MockitoAnnotations.initMocks(this);
}
#Test
public void testGetOrganizations() {
LocalDate localDate = LocalDate.now();
List<OrganizationTypeEnum> organizationTypes = new ArrayList<OrganizationTypeEnum>();
organizationTypes.add(OrganizationTypeEnum.All);
List<AllocationStatusEnum> allocationStatuses = new ArrayList<AllocationStatusEnum>();
allocationStatuses.add(AllocationStatusEnum.ALL);
List<IOrganization> organizations = new ArrayList<IOrganization>();
IOrganization organization = new Organization();
organization.setOrganizationId(1);
organizations.add(organization);
Mockito.when(organizationsDao.getOrganizations(isA(LocalDate.class), isA(List.class), isA(List.class))).thenReturn(organizations);
List<IOrganization> orgs = organizationsService.getOrganizations(localDate, organizationTypes, allocationStatuses);
assertNotNull(orgs);
}
}
The service class is this,
public class OrganizationsService extends AbstractService implements IOrganizationsService {
#Autowired
IOrganizationsDao organizationsDao;
/**
* #param organizationsDao the organizationsDao to set
*/
public void setOrganizationsDao(IOrganizationsDao organizationsDao) {
this.organizationsDao = organizationsDao;
}
#Override
public List<IOrganization> getOrganizations(LocalDate effectiveDate, List<OrganizationTypeEnum> organizationTypes, List<AllocationStatusEnum> allocationStatuses) {
return organizationsDao.getOrganizations(effectiveDate, organizationTypes, allocationStatuses);
}
and the DAO is this,
public class OrganizationsDao extends AbstractDao implements IOrganizationsDao {
#Override
public List<IOrganization> getPendingOrganizations(LocalDate effectiveDate) {
// TODO Auto-generated method stub
return null;
}
#Override
public List<IOrganization> getOrganizations(LocalDate effectiveDate, List<OrganizationTypeEnum> organizationTypeEnums,
List<AllocationStatusEnum> allocationStatuses) {
// TODO Auto-generated method stub
return null;
}
I think the issue here is that while mocking the method call you are using isA for parameters. As per my understanding, isA method is used for the verification not for passing the parameters. Try any method instead:
Mockito.when(organizationsDao.getOrganizations(any(LocalDate.class), any(List.class), any(List.class))).thenReturn(organizations);

Android How to add external dependency (context) to SubComponent builder in Dagger 2.1.0

I am using dependency injection according to google sample
The only external dependency I can pass is through AppComponent builder
#Singleton
#Component(modules = {
AndroidInjectionModule.class,
AppModule.class,
MainTabActivityModule.class,
CoreActivityModule.class
})
public interface AppComponent {
#Component.Builder
interface Builder {
#BindsInstance
Builder application(Application application);
AppComponent build();
}
void inject(MyApplication myApplication);
}
and injected in app like this
#Override
public void onCreate() {
super.onCreate();
DaggerAppComponent
.builder()
.application(myApplication)
.build().inject(myApplication);
...
}
According to document injecting in Activity looks like this. I added what I would like to achieve.
public class YourActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
AndroidInjection
//.builder() THIS IS WHAT I WANT TO ACHIEVE
//.addActivityContext(this) THIS IS WHAT I WANT TO ACHIEVE
//.build() THIS IS WHAT I WANT TO ACHIEVE
.inject(this);
super.onCreate(savedInstanceState);
}
}
but the question is how can I add additional parameter to subComponent.
#Subcomponent
public interface CoreActivitySubComponent extends AndroidInjector<CoreAppActivity> {
// #Subcomponent.Builder
// interface Builder {
// Builder addContext(Context context) //did not work
// CoreActivitySubComponent build(); //did not work
// }
//==or using abstract class
// in this option I do not know where to add parameter to this builder
#Subcomponent.Builder
public abstract class Builder extends AndroidInjector.Builder<CoreAppActivity> {
}
}
Did you add the ContextModule to your #Subcomponent similar to this answer?
I think your #Subcomponent should look something like this:
#Subcomponent(module = {ContextModule.class})
interface MainTabActivityComponent extends AndroidInjector<CoreAppActivity> {
#Subcomponent.Builder
public abstract class Builder extends AndroidInjector.Builder<CoreAppActivity> {
abstract Builder addContextModule(ContextModule contextModule);
#Override
public void seedInstance(CoreAppActivity instance) {
addContextModule(new ContextModule(instance));
}
}
}
And finally don't forget to include this #Subcomponent in your binding-module.
One last question: is this really required?
I found that using the AndroidInjector on the Application as well as Activities and Fragments will give me the correct corresponding Context when I inject it.
The problem was that Dagger 2.1.0 method AndroidInjection.inject(this); which is supposed to be used in Activity and Fragment, do not provide any builder to add external dependency.
I wanted to create general module which depends on Activity/Fragment context.
sample:
public class ToastController {
private Context context;
#Inject
public ToastController(Context context) {
this.context = context;
}
public void showToast(#StringRes int res) {
Toast.makeText(context, context.getText(res), Toast.LENGTH_SHORT).show();;
}
}
But I was not able to generalize it to the level, that I could provide just one context modude, instead I had to do create binds module for every single Activity/ Fragment that uses this module.
#Singleton
#Component(modules = {
AndroidInjectionModule.class,
AppModule.class,
MainTabActivityModule.class,// IMPORTANT CLASS
})
public interface AppComponent {
#Component.Builder
interface Builder {
#BindsInstance
Builder application(Application application);
AppComponent build();
}
void inject(MyApplication myApplication);
}
This is a place, where I provide context module for each Activity
#Module
public abstract class MainTabActivityModule
#ContributesAndroidInjector(modules = ContextMainTabActivityModule.class)//THIS MODULE
abstract MainTabActivity contributeMainActivity();
}
and Context is provided using #Binds annotation
#Module
public abstract class ContextMainTabActivityModule {
#Binds
abstract Context provideContext(MainTabActivity featureActivity);
}
=====================
It can be done by overriding method seedInstance according to sample
I tried this, but it did not work for me
#Subcomponent.Builder
public abstract class Builder extends AndroidInjector.Builder<CoreAppActivity> {
abstract Builder addContextModule(ContextModule contextModule);
#Override
public void seedInstance(CoreAppActivity instance) {
addContextModule(new ContextModule(instance));
}
}
next class
#Module
public class ContextModule {
private CoreAppActivity coreAppActivity;
#Provides
Context getContext() {
return coreAppActivity.getBaseContext();
}
public ContextModule(CoreAppActivity coreAppActivity) {
this.coreAppActivity = coreAppActivity;
}
}

Guice module integration issue with REST

Guice module integration issue with REST
I have define one AOP guice based module, but when I tried to integrate with REST code, methodInvocation.proceed retun null.
What might be best way to solve this issue.
Define AOP Guice based module as below
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.METHOD)
#interface NotOnWeekends {}
public class WeekendBlocker implements MethodInterceptor {
public Object invoke(MethodInvocation invocation) throws Throwable {
Calendar today = new GregorianCalendar();
if (today.getDisplayName(DAY_OF_WEEK, LONG, ENGLISH).startsWith("S")) {
throw new IllegalStateException(
invocation.getMethod().getName() + " not allowed on weekends!");
}
return invocation.proceed();
}
}
public class NotOnWeekendsModule extends AbstractModule {
protected void configure() {
bindInterceptor(Matchers.any(), Matchers.annotatedWith(NotOnWeekends.class),
new WeekendBlocker());
}
}
But I tried to Integrate this with my REST API
public class WorkerBean implements Worker {
#Autowired
private WorkerRepository workerRepository;
#Override
#NotOnWeekends
public Collection<Worker> findAll() {
Collection<Worker> workers = workerRepository.findAll();
return workers;
}
#RestController
public class WorkerController {
#RequestMapping(
value = "/api/workers",
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Collection<Worker>> getWorkers() {
Worker worker = Guice.createInjector(new NotOnWeekendsModule()).getInstance(Worker.class);
Collection<Worker> worker = worker.findAll(); // return null
....
}

Junit 4 + Eclipse - Run inner class test cases with SpringJUnit4ClassRunner as well

I need to run inner class test cases from eclipse using Junit4. I understand that there is org.junit.runners.Enclosed that is intended to serve this purpose. It works well for "plain" unit test i.e. without the need for spring context configuration.
For my case, give sample code below, Adding another annotation of Enclosed does not work since there is a conflict of both SpringJUnit4ClassRunner and Enclosed test runners. How can I solve this problem ?
Note: Kindly ignore any basic spelling mistake/basic import issues in the below example since I tried to cook up from my actual use-case.
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = { "/unit-test-context.xml"})
public class FooUnitTest {
// Mocked dependency through spring context
#Inject
protected DependentService dependentService;
public static class FooBasicScenarios extends FooUnitTest{
#Test
public void testCase1 {
.....
List<Data> data = dependentService.getData();
.....
}
}
public static class FooNeagativeScenarios extends FooUnitTest{
#Test
public void testCase1 {
.....
List<Data> data = dependentService.getData();
.....
}
}
}
}
FooUnitTest is a container, you cannot use it as a superclass.
You need to move all your spring-code to Scenario-classes. And use #RunWith(Enclosed.class). For example, with abstract superclass
#RunWith(Enclosed.class)
public class FooUnitTest {
#ContextConfiguration(locations = { "/unit-test-context.xml"})
protected abstract static class BasicTestSuit {
// Mocked dependency through spring context
#Inject
protected DependentService dependentService;
}
#RunWith(SpringJUnit4ClassRunner.class)
public static class FooBasicScenarios extends BasicTestSuit {
#Test
public void testCase1 {
.....
List<Data> data = dependentService.getData();
.....
}
}
#RunWith(SpringJUnit4ClassRunner.class)
public static class FooNeagativeScenarios extends BasicTestSuit {
#Test
public void testCase1 {
.....
List<Data> data = dependentService.getData();
.....
}
}
}
Of course you can declare all dependencies in each Scenario-class, in that case there is no necessary in abstract superclass.

Run Current Junit Test in GWTTestCase

I have a JUnit test that I run on one class, but I recently wrote an emulated version for GWT. Since the specification is the same, I would like to use the same test case, but I want it to run in the GWT environment, which would typically be accomplished by extending GWTTestCase.
I really want to avoid any copy/paste nonsense, because there are likely to be added tests in the future, which I should not be burdened with copying later.
How can I import/inherit my standard unit test to be run as either a regular test case or a GWT test case?
I have found the solution to this problem.
If you extend the original test with GWTTestCase, you can override getModuleName to return null. This tells GWTTestCase to run as a normal pure java test (no translation at all).
You can then extend this test case with one that overrides getModuleName to return a module name, and the same tests will be run with translation.
Basically:
public class RegularTest extends GWTTestCase {
#Override
public String getModuleName() { return null; }
public void testIt() {...}
}
...and the GWT version...
public class GwtTest extends RegularTest {
#Override
public String getModuleName() { return "some.module"; }
}
The downside to this is that it forces you to use JUnit3 style tests, which I find a little annoying, but it beats the alternative.
I think there is no easy way .. But you can extract an interface of your junit test, gwt test case and junit test case implements this interface. You can create a third class for implementation, all test call methods of gwt test case and junit test are delegated to this implementation class.
public interface IRegularTest {
public void testSomething();
public void testSomething2();
}
public class RegularTestImpl implements IRegularTest {
public void testSomething(){
// actual test code
}
public void testSomething2(){
// actual test code
}
}
public class RegularTest extends TestCase implements IRegularTest {
IRegularTest impl = new RegularTestImpl();
public void testSomething(){
impl.testSomething
}
public void testSomething2(){
}
}
public class GwtTest extends TestCase implements IRegularTest {
IRegularTest impl = new RegularTestImpl();
public void testSomething(){
impl.testSomething
}
public void testSomething2(){
}
}
