I'm currently using Subsonic 3.03 Active Record repository.
I have setup a Test connection string to utilise the dummy internal storage.
[TestInitialize]
public void TestInitialize()
{
List<ServiceJob> jobs = new List<ServiceJob>()
{
new ServiceJob() { ServiceJobID = 1 },
new ServiceJob() { ServiceJobID = 2 }
};
ServiceJob.Setup(jobs);
}
[TestMethod]
public void TestMethod()
{
ServiceJob job = ServiceJob.SingleOrDefault(s => s.ServiceJobID == 2);
Assert.AreEqual(2, job.ServiceJobID);
}
I'm expecting this unit-test to pass, but it pulls out the first service job and fails.
I've also experienced problems using other sugar methods such as .Find().
It works fine when using the IQueryable interface such as ServiceJob.All.Where(s => s.ServiceJobID == 2) but don't fancy stripping out the sugar for testing purposes!
Great product by the way, really impressed so far.
As you say this looks like it's definitely a bug. You should submit it as an issue to github:

I've done a bunch of searching and, while I've found a few hits, like Why does Spock think my Data Provider has no data?, none of them seem to be very helpful.
I've only done a data provider a couple of times, but it seems perfect for this. I have the following static method:
static List<ContactPointType> getAddressTypes() {
List<ContactPointType> result = new ArrayList<>();
for (ContactPointType cpType : ContactPointType.values()) {
if (cpType.toString().endsWith("Addr")) {
result.add(cpType);
}
}
return result;
}
And then I'm trying to use it as a data provider for calling a function on my class:
#Unroll("#cpType should be address")
def "isAddress addresses"() {
expect: "isAddress() to be true"
contactPoint.isAddress(cpType)
where:
cpType << getAddressTypes()
}
When I run this, I get:
org.spockframework.runtime.SpockExecutionException: Data provider has no data
at org.spockframework.runtime.JUnitSupervisor.afterFeature(JUnitSupervisor.java:191)
at org.spockframework.runtime.BaseSpecRunner.runFeature(BaseSpecRunner.java:236)
Like I said, it seems pretty straightforward. Does anyone have any ideas?
Well, I've tried the data provider feature and it works as expected:
#Unroll("max(1, #cpType) == #cpType")
class MyFirstSpec extends Specification {
def "let's try this!"() {
expect:
Math.max(1, cpType) == cpType
where:
cpType << dataProvider()
}
List<Integer> dataProvider() {
[2,3,4]
}
}
However if I rewrite the dataProvider function like this, I see the exception that you've mentioned:
List<Integer> dataProvider() {
[] // returns an empty list
}
Yields:
org.spockframework.runtime.SpockExecutionException: Data provider has no data
at org.spockframework.runtime.JUnitSupervisor.afterFeature(JUnitSupervisor.java:180)
at org.spockframework.runtime.BaseSpecRunner.runFeature(BaseSpecRunner.java:239)
So my idea is that probably you end up with an empty list in the data provider implementation and that's why it doesn't work
Another possible (although slightly less realistic idea to be honest) is that you've messed something up with Groovy/Java interconnection
So in terms of resolution to wrap up:
Try to use some more straightforward data provider implementation and test it
If it doesn't work - just define data provider like me in Groovy and re-test
I am writing unit tests for my Generic Repository layer but i have some problems with DbEntityEntry.
My Update method is like below.
public virtual void Update(TEntity entityToUpdate) {
var entity = dbSet.Find(context.Entry<ITrackedEntity>(entityToUpdate).Entity.Id);
context.Entry(entity).CurrentValues.SetValues(entityToUpdate);
}
As you can see, context.Entry<TEntity>(TEntity entity) method is invoked by caller. So while unit tests this code throws null exception.
I had tried to mock context.Entry method but i couldn't because i couldn't provide return value.
My current test method is below
[Fact]
public void UpdateTest() {
AssetType _sample1 = new AssetType() {
AssetTypeID = 1,
IsContainer = true,
Name = "Sample 1"
};
IDbSet<AssetType> assetTypeDbSet = new FakeDbSet<AssetType>(_sample1);
Mock<IDbContext> mockContext = new Mock<IDbContext>();
mockContext.Setup(pc => pc.Set<AssetType>()).Returns(assetTypeDbSet);
_sample1.Name = "Sample 1.1";
var dbEntity = mockContext.Object.Entry<ITrackedEntity>(_sample1);
mockContext.Setup(p => p.Entry<ITrackedEntity>(It.IsAny<AssetType>())).Returns(dbEntity);
using(GenericRepository<AssetType> repo = new GenericRepository<AssetType>(mockContext.Object)) {
repo.Update(_sample1);
var result = repo.GetAll(0, 0);
Assert.Equal(1, result.Count);
var singleResult = repo.GetByID(1);
Assert.Equal(_sample1.Name, singleResult.Name);
}
}
I tried to get DbEntityEntry value by calling context.Entry<>() method at test but that wa returned null, too.
Also this class cannot be iniated with new operator. So i stucked..
And what is the point of unit testing this code? You fake the Find method, then you fake DbEntityEntry and there will be no real logic to test.
Anyway EF code is not unit testable in general. That is one reason why people believe that repository will help them because they mock / fake their repository when testing upper layer. Repository is then tested with integration tests to make sure that everything in EF and database works as expected.
You will not fake DbEntityEntry with Moq. Maybe with TypeMock Isolator or MS Fakes you will be able to do more but it is not needed in your sample code.
I tried making a form in GXT to upload files, but I see more examples on the net, I failed to make it work a simple FileUploadField to save the file locally.
Cde fragment:
formPanel = new FormPanel();
formPanel.setBodyBorder(false);
formPanel.setHeaderVisible(false);
formPanel.setAction(GWT.getModuleBaseURL() + "fileUpload");
formPanel.setEncoding(Encoding.MULTIPART);
formPanel.setMethod(Method.POST);
formPanel.setButtonAlign(HorizontalAlignment.CENTER);
formPanel.setHeaderVisible(true);
fileUploadField = new FileUploadField();
fileUploadField.setName("fileName");
fileUploadField.setAllowBlank(false);
fileUploadField.setFieldLabel("Archivo");
fileUploadField.addListener(Events.OnChange, new Listener<BaseEvent>() {
public void handleEvent(BaseEvent BaseEvent) {
aSubmitButton.setEnabled(true);
}
});
aSubmitButton = new Button("OK");
aSubmitButton.setEnabled(false);
aSubmitButton.setId("submit_button");
aSubmitButton.addSelectionListener(new SelectionListener<ButtonEvent>() {
#Override
public void componentSelected(ButtonEvent inButtonEvent) {
formPanel.submit();
}
});
The above code is the declaration of FormPanel and FileUploadField.
We use gwtupload-0.6.3-compat.jar library to do the job.
Basically, the idea is that on the server side you need to create a servlet, which is going to be accepting your uploaded files. The mentioned library provides UploadAction servlet extension facilitating that.
On the client side you can use one of gwtupload components. We use MultiUploader for instance. That's literally a few lines of code there. Main code is in the listener:
private IUploader.OnFinishUploaderHandler onFinishUploaderHandler = new IUploader.OnFinishUploaderHandler() {
public void onFinish(IUploader uploader) {
if (uploader.getStatus() == Status.SUCCESS) {
// What you want to do when file is uploaded.
}
}
};
The rest is taken care of by the component. Since the library is for GWT, it comes with source code, so you can see what it's doing behind the scene and read extensive comments in the code.
Free to use of course.
I'm getting into TDD; using nUnit and RhinoMocks 3.5.
I'm trying to figure out how to AssertWasCalled on a method in the SystemUnderTest (SUT). My understanding is that you can't mock the system under test. In fact, my current test results in an exception because the I'm using the AssertWasCalled on the SUT.
OrdersPresenter:
public void OnViewLoad_GetOrders()
{
var orders = GetOrders();
View.Model.Orders = orders;
}
public List<Orders> GetOrders()
{
return _ordersRepository.GetAll();
}
OrdersPresenterTest:
_ordersPresenter = new OrdersPresenter(_view, _ordersRepository);
[Test]
public void OnViewLoad_GetOrders_Should_Call_GetOrders()
{
_view.Raise(v => v.LoadOrders += _ordersPresenter.OnViewLoad_GetOrders, view, new EventArgs);
_ordersPresenter.AssertWasCalled(d => d.GetOrders); // Getting non-mock exception here
}
How do I Assert GetOrders was called in the SUT? I haven't been able to figure it out in the docs.
Any help is greatly appreciated.
Edit:
I understand the GetOrders method in the SUT should be private. I went back thru Roy Osherove's Art of Unit Testing to see how to test private methods. Roy says making a method public (to test against) is not necessarily a bad thing, so I will keep it public.
So I've written a test for GetOrders and I assert the return value ShouldBe a list of orders. That said, I believe I need to restructure my test for OnViewLoad_GetOrders by stubbing the value I get from GetOrders and asserting the results of my actions on that object.
Can someone confirm and explain?
You can not use AssertWasCalled() on not-mocked objects. Just abstract class OrdersPresenter by an interface (use Extract Interface refactoring technique) and then
var ordersPresenter = MockRepository.GenerateMock<IOrderRepository>();
view.Raise(...);
_ordersPresenter.AssertWasCalled(d => d.GetOrders);
BTW,
for me it is not clear why RhinoMocks not used generic parameter constraint for AssertWasCalled
public static void AssertWasCalled<T>(this T mock, Action<T> action,
Action<IMethodOptions<object>> setupConstraints)
Basically T is not limited, but I believe it would be better limit it to somethign like IMockMarkerInterface
I have been trying to follow this example (download the source code from a link on the site or here, but I keep running into an error that seems embedded in the example.
My procedure has been as follows (after installing the AppFabric SDK and other dependencies):
Download the source
Create a Service Namespace on the AppFabric.
Import the project into a new Windows Azure project with one Worker Role, make sure that it all compiles and that the default Worker Role Run() method starts and functions.
Configure the method GetInterRoleCommunicationEndpoint in InterRoleCommunicationExtension.cs with the ServiceNameSpace and IssuerSecret from my AppFabric Service Namespace (IssuerName and ServicePath stay default). This is a hard-wiring of my own parameters.
Copy/paste the initialization logic from the "SampleWorkerRole.cs" file in the demo into the OnStart() method of my project's Worker Role
Comment-out references to Tracemanager.* as the demo code does not have the Tracemanager methods implemented and they're not crucial for this test to work. There are about 7-10 of these references (just do a Find -> "Tracemanager" in entire solution).
Build successfully.
Run on local Compute Emulator.
When I run this test, during the initialization of a new InterRoleCommunicationExtension (the first piece of the inter-role communication infrastructure to be initialized, this.interRoleCommunicator = new InterRoleCommunicationExtension();), an error is raised: "Value cannot be null. Parameter name: contractType."
Drilling into this a bit, I follow the execution down to the following method in ServiceBusHostFactory.cs (one of the files from the sample):public static Type GetServiceContract(Type serviceType)
{
Guard.ArgumentNotNull(serviceType, "serviceType");
Type[] serviceInterfaces = serviceType.GetInterfaces();
if (serviceInterfaces != null && serviceInterfaces.Length > 0)
{
foreach (Type serviceInterface in serviceInterfaces)
{
ServiceContractAttribute serviceContractAttr = FrameworkUtility.GetDeclarativeAttribute<ServiceContractAttribute>(serviceInterface);
if (serviceContractAttr != null)
{
return serviceInterface;
}
}
}
return null;
}
The serviceType parameter's Name property is "IInterRoleCommunicationServiceContract," which is one of the classes of the demo, and which extends IObservable. The call to serviceType.GetInterfaces() returns the "System.IObservable`1" interface, which is then passed into FrameworkUtility.GetDeclarativeAttribute(serviceInterface);, which has the following code:
public static IList GetDeclarativeAttributes(Type type) where T : class
{
Guard.ArgumentNotNull(type, "type");
object[] customAttributes = type.GetCustomAttributes(typeof(T), true);
IList<T> attributes = new List<T>();
if (customAttributes != null && customAttributes.Length > 0)
{
foreach (object customAttr in customAttributes)
{
if (customAttr.GetType() == typeof(T))
{
attributes.Add(customAttr as T);
}
}
}
else
{
Type[] interfaces = type.GetInterfaces();
if (interfaces != null && interfaces.Length > 0)
{
foreach (object[] customAttrs in interfaces.Select(iface => iface.GetCustomAttributes(typeof(T), false)))
{
if (customAttrs != null && customAttrs.Length > 0)
{
foreach (object customAttr in customAttrs)
{
attributes.Add(customAttr as T);
}
}
}
}
}
return attributes;
}</code><br>
It is here that the issue arises. After not finding any customAttributes on the "IObservable1" type, it calls type.GetInterfaces(), expecting a return. Even though type is "System.IObservable1," this method returns an empty array, which causes the function to return null and the exception with the above message to be raised.
I am extremely interested in getting this scenario working, as I think the Publish/Subscribe messaging paradigm is the perfect solution for my application. Has anyone been able to get this demo code (from the AppFabric CAT Team itself!) working, or can spot my error? Thank you for your help.
