I am trying to write following database test with cucumber :
#Given("^I have N foos$")
public void i_have_N_foos() throws Throwable {
JPA.withTransaction(() -> {
fooSize = foo.count();
});
}
foot.count() should be in a transaction butJPA.withTransaction method is deprecated. How can I use JPAApi with my cucumber test?
Fixed with :
public class Foo{
JPAApi jpaApi;
#Given("^I have N foos$")
public void i_have_N_foos() throws Throwable {
jpaAPI= JPA.createFor("fooPersistenceUnit");
jpaApi.withTransaction(() -> {
fooSize = foo.count();
});
}
}

after reading this article I was sure to write my own Assertions but I failed. :-(
We have an interface which looks like this:
public class ApplicationException extends RuntimeException {
public String enhancedStatus() {
return getClass().getSimpleName();
}
}
I wrote my own EnhancedStatusAssert like described in the artile.
public class EnhancedStatusAssert extends AbstractAssert<EnhancedStatusAssert, ApplicationException> {
public EnhancedStatusAssert(ApplicationException actual) {
super(actual, EnhancedStatusAssert.class);
}
public static EnhancedStatusAssert assertThat(ApplicationException actual) {
return new EnhancedStatusAssert(actual);
}
public EnhancedStatusAssert hasEnhancedCause(String enhancedStatus) {
isNotNull();
// check condition
if (!actual.enhancedStatus().equals(enhancedStatus)) {
failWithMessage("Expected enhanced status to be <%s> but was <%s>", enhancedStatus, actual.enhancedStatus());
}
return this;
}
}
Which works fine but then I have trouble to override assertThatThrownBy
assertThatThrownBy(() -> { throw new ApplicationException()})
.isInstanceOf(ApplicationException.class)
.hasEnhancedCause("cause");
What is the way to get it to run?
Thanks,
Markus
Try using asInstanceOf https://assertj.github.io/doc/#assertj-core-3.13.0-asInstanceOf you can write your own InstanceOfAssertFactory for your ApplicationException.
If you only have one field to check you can extract it with ... extracting and chain assertions on the extracted value.
I m trying create unit tests for one project.I m facing a problem because when I try control the result of an interface(mock). When the code get the Interface variable that return a NullPointerException.
Firstly I tried #Override the method in my test class (ClassA), but it don't work. After that I tried mock the interface object and control the comportment with Mockito.When().tehnReturn();
I will put here my code, I read some solutions but none works.
My Interface:
#FunctionalInterface
public interface Interface {
UpdateXResponse process(UpdateXRequest request) throws Exception;
}
The class I want to test:
#Service(ClassA.class)
public class ClassA extends VService implements UpdateX {
#Reference
#Inject
private Interface interface;
#Inject
public ClassA(...) {...}
#Override
public UpdateXResponse process(UpdateXRequest request) throws Exception {
UpdateXResponse response = initResponse(context, request, new UpdateXResponse());
UpdateXInput input = request.getInput();
UpdateXOutput output = new UpdateXOutput();
response.setOutput(output);
try {
firstMethodCall(...);
} catch (Exception t) {
throwCorrectException(t, logger);
}
return response;
}
private void firstMethodCall(...) throws Exception {
TypeF typeF = callInterfaceMethod(...);
...
}
/**
* Orchestrates Interface service
*/
protected TypeF callInterfaceMethod(...) {
...
request.setInput(input);
request.setHeader(header);
InterfaceResponse response = interface.process(request); // LINE ERROR - In this step interface is NULL when the test get this
return response;
}
}
And finally my class test:
#RunWith(PowerMockRunner.class)
#PrepareForTest(value = {ClassA.class,Interface.class} )
public class WithPowerMockUnitTest{
#InjectMocks
private ClassA classA;
private Interface interface;
#Before
public void setUp() throws Exception {
InterfaceRequest InterfaceRequest = createInterfaceRequest();
InterfaceResponse serviceUnavailableResponse = createInterfaceResponse();
Interface = Mockito.mock(Interface.class);
when(Interface.process(Mockito.any(InterfaceRequest.class))).thenReturn(serviceUnavailableResponse);
}
#Test
public void testh() throws SOAException {
InterfaceResponse res = interface.process(Mockito.any(InterfaceRequest.class)); // There all run ok. The interface is not null and return what i expected.
System.out.println("RES "+res);
}
#Test
public void test() {
assertNotNull(classA); // not null
assertNotNull(interface); // not null
}
#Test
public void newTest() throws Exception {
InterfaceRequest InterfaceRequest = createInterfaceRequest();
InterfaceResponse serviceUnavailableResponse = createInterfaceResponse();
UpdateXResponse response = ClassA.process(updateXRequest()); // PROBLEM!! When that get the LINE ERROR the interface is null! WHY?
}
}
I put some comments in the lines where the problem exists for me.
public interface A{
Response process(Request r) throws Exception;
}
public class B{
private Class_That_Override_Interface_method ctoim;
public Response function(){
X res = method_B();
}
protected X method_B(){
response res = ctoim.process(request); // That ctoim is always NULL when the test get that line/call
}
}
Thanks
You're missing the #Mock annotation on your Interface variable.
Therefore the mock is not injected into your classA and the newTest() fails. (In this case remove Interface = Mockito.mock(Interface.class); from the setUp method).
Alternativly remove the #InjectMocks annotation and create your class under test manually passing your mock into the constructor.
For this specific case (assuming its a different case from the last question)
there doesn't seem to be a need to involve PowerMockito. So unless you left out some relevant parts you might as well just use the MockitoJUnitRunner.
Ps.:
Also remeber what I said last time about compilable examples?
interface is a keyword and can't be used for variables.
You should also aim to write variables identical all the times (not Interface and interface / classA and ClassA)
And in case you haven't read it yet check out the help section about minmal reproducible examples.
Edit:
I fogot to mention that the line interface.process(Mockito.any(InterfaceRequest.class)); in testh() is actually invalid syntax. You should use ArgumentMatchers only for parameters of mocked methods.
Also consider adding the MockitoAnnotations.initMocks(this); to your setUp method, when using the PowerMockRunner.
i'm new with silverlight/ria and i have a problem wath i don't understand.
I have the following code in my domain services class
[EnableClientAccess()]
[KnownType(typeof(ModeleEmailEa))]
[KnownType(typeof(ModeleSmsEa))]
public class EAEMailDomainService : DomainService
{
#region ModeleEnvoiEa CRUD
[Query()]
public IQueryable<ModeleEnvoiEa> SelectAllModeleEnvoiEa()
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
return modeleService.GetList<ModeleEnvoiEa>();
}
[Update]
public void UpdateModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Update(modele);
}
[Insert]
public void InsertModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Insert(modele);
}
[Delete]
public void DeleteModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Delete(modele);
}
[Invoke]
public void Test(int valeur)
{
//Do something
}
#endregion
And this code in my Silverlight application
Context.Test(2, action =>
{
// Do something
}, null);
The function SelectAll, Update, Delete , Insert work's fine but the 'Test' function generated the following error:
an attempt was made to load a program
with an incorrect format
any ideas ?
I have found that if i write the function invocation like this it's works
Context.Test(2,new System.Action<InvokeOperation<Int>>(ModeleEnvoiEa_Completed),null);
}
void ModeleEnvoiEa_Completed(InvokeOperation invoke)
{
// Do something
}
but if i use a lambda expression like this, i have an error, why ?
Context.Test(2, action =>
{
// This code generate an error
// an attempt was made to load a program with an incorrect format
}, null);
I'm considering re-rewriting some of my MVC controllers to be async controllers. I have working unit tests for these controllers, but I'm trying to understand how to maintain them in an async controller environment.
For example, currently I have an action like this:
public ContentResult Transaction()
{
do stuff...
return Content("result");
}
and my unit test basically looks like:
var result = controller.Transaction();
Assert.AreEqual("result", result.Content);
Ok, that's easy enough.
But when your controller changes to look like this:
public void TransactionAsync()
{
do stuff...
AsyncManager.Parameters["result"] = "result";
}
public ContentResult TransactionCompleted(string result)
{
return Content(result);
}
How do you suppose your unit tests should be built? You can of course invoke the async initiator method in your test method, but how do you get at the return value?
I haven't seen anything about this on Google...
Thanks for any ideas.
As with any async code, unit testing needs to be aware of thread signalling. .NET includes a type called AutoResetEvent which can block the test thread until an async operation has been completed:
public class MyAsyncController : Controller
{
public void TransactionAsync()
{
AsyncManager.Parameters["result"] = "result";
}
public ContentResult TransactionCompleted(string result)
{
return Content(result);
}
}
[TestFixture]
public class MyAsyncControllerTests
{
#region Fields
private AutoResetEvent trigger;
private MyAsyncController controller;
#endregion
#region Tests
[Test]
public void TestTransactionAsync()
{
controller = new MyAsyncController();
trigger = new AutoResetEvent(false);
// When the async manager has finished processing an async operation, trigger our AutoResetEvent to proceed.
controller.AsyncManager.Finished += (sender, ev) => trigger.Set();
controller.TransactionAsync();
trigger.WaitOne()
// Continue with asserts
}
#endregion
}
Hope that helps :)
I've written short AsyncController extension method that simplifies unit testing a bit.
static class AsyncControllerExtensions
{
public static void ExecuteAsync(this AsyncController asyncController, Action actionAsync, Action actionCompleted)
{
var trigger = new AutoResetEvent(false);
asyncController.AsyncManager.Finished += (sender, ev) =>
{
actionCompleted();
trigger.Set();
};
actionAsync();
trigger.WaitOne();
}
}
That way we can simply hide threading 'noise':
public class SampleAsyncController : AsyncController
{
public void SquareOfAsync(int number)
{
AsyncManager.OutstandingOperations.Increment();
// here goes asynchronous operation
new Thread(() =>
{
Thread.Sleep(100);
// do some async long operation like ...
// calculate square number
AsyncManager.Parameters["result"] = number * number;
// decrementing OutstandingOperations to value 0
// will execute Finished EventHandler on AsyncManager
AsyncManager.OutstandingOperations.Decrement();
}).Start();
}
public JsonResult SquareOfCompleted(int result)
{
return Json(result);
}
}
[TestFixture]
public class SampleAsyncControllerTests
{
[Test]
public void When_calling_square_of_it_should_return_square_number_of_input()
{
var controller = new SampleAsyncController();
var result = new JsonResult();
const int number = 5;
controller.ExecuteAsync(() => controller.SquareOfAsync(number),
() => result = controller.SquareOfCompleted((int)controller.AsyncManager.Parameters["result"]));
Assert.AreEqual((int)(result.Data), number * number);
}
}

I want to intercept the creation of an instance in SM and I'm trying the following but it's not calling the InstanceInterceptor implementation, does anyone know why?
ForRequestedType<IPublishResources>()
.TheDefault
.Is
.OfConcreteType<PublisherService>()
.InterceptWith(new PublisherServiceInterceptor());
The test code uses the ObjectFactory to create instances, and is shown below:
// Given we have a configure object factory in StructureMap...
ObjectFactory.Configure(x => x.AddRegistry(new StructureMapServiceRegistry()));
// When we request a publisher service...
var publisher = ObjectFactory.GetInstance<IPublishResources>();
Cheers

I could not reproduce your problem in release 2.5.4. Here is my code.
public interface IPublishResources {}
class PublishResources : IPublishResources {}
public class LoggingInterceptor : InstanceInterceptor
{
//this interceptor is a silly example of one
public object Process(object target, IContext context)
{
Console.WriteLine("Interceptor Called");
return context.GetInstance<PublishResources>();
}
}
public class MyRegistry : Registry
{
public MyRegistry()
{
For<IPublishResources>()
.Use<PublishResources>()
.InterceptWith(new LoggingInterceptor());
}
}
[TestFixture]
public class Structuremap_interception_configuraiton
{
[Test]
public void connecting_implementations()
{
var container = new Container(cfg =>
{
cfg.AddRegistry<MyRegistry>();
});
container.GetInstance<IPublishResources>();
}
}
A question. Do you really need to use an Interceptor here? If you only need to define a factory you can do somethign like this.
public interface IPublishResourcesFactory
{
IPublishResources Create();
}
public class MyRegistry : Registry
{
public MyRegistry()
{
For<IPublishResources>().Use(c =>
{
return c.GetInstance<IPublishResourcesFactory>().Create();
});
//or
For<IPublishResources>().Use(c =>
{
//other object building code.
return new PublishResources();
});
}
}
