Hi Patrick,
Thanks for the reply! I'm a big fan of your writings.
Details: I have a wcf web service and the interface has lots of stuff
in it, but I am mainly interested in making a call to one of these
services to have it get data from the database and return it to my SL4
application. That part of the interface includes:
public interface IDataService : IMACSWcfService
{
...
void
GetStopEventsAsync(System.Collections.Generic.Dictionary<string,
string> param, object userState);
event System.EventHandler<GetStopEventsCompletedEventArgs>
GetStopEventsCompleted;
...
}
I have a search class that will need to call this DataService async
and in the production code I will need to do something like this:
1. Pass in the IDataService implementation using constructor injection
to the Search class
2. Save this locally in the Search class
3. Create a method in Search that will call the ws to get the data
4. When the data is returned an event is raised and the callback is
executed
5. The callback saves the returned data
If want to TDD this with Rhino/MSTest then
private MockRepository mockRepository;
private IDataService mockDS;
[TestMethod]
public void SearchForStopEventsShouldCallGetStopEventsAsync()
{
// Arrange:
mockRepository = new MockRepository();
mockDS = mockRepository.StrictMock<IDataService>();
Search sut = new Search(mockDS);
// Act:
sut.GetStopEvents(GlobalVariables.SearchType.ByLoadId);
// Assert:
RhinoMocksExtensions.AssertWasCalled(mockDS.GetStopEventsAsync(null,
null));
}
[TestMethod]
public void
SearchForStopEventsShouldRegisterCallbackEvent_OnDataReturned()
{
// Arrange:
mockRepository = new MockRepository();
mockDS = mockRepository.StrictMock<IDataService>();
Search sut = new Search(mockDS);
// Act:
sut.GetStopEvents(GlobalVariables.SearchType.ByLoadId);
// Assert:
}
[TestMethod]
public void
SearchForStopEventsShouldCallbackEvent_OnDataReturned_WhenEventIsRaised()
{
// Arrange:
mockRepository = new MockRepository();
mockDS = mockRepository.StrictMock<IDataService>();
Search sut = new Search(mockDS);
// Act:
sut.GetStopEvents(GlobalVariables.SearchType.ByLoadId);
// Assert:
}
Here is what my production code will look like:
public class Search : ISearch
{
private readonly IDataService _dataService;
public Search(IDataService ds)
{
_dataService = ds;
}
public void GetStopEvents(GlobalVariables.SearchType st)
{
try
{
_dataService.GetStopEventsCompleted +=
OnDataReturned; ;
_dataService.GetStopEventsAsync(_param, st);
}
catch (Exception ex)
{
if (!ViewModelLocator.IsMACSAdjustmentVMNull)
{
ViewModelLocator.MACSAdjustmentViewModelStatic.ReturnedMessage =
ex.Message;
}
throw new Exception(ex.Message);
}
void OnDataReturned(object sender,
GetStopEventsCompletedEventArgs e)
{
var args = new GetDataDoneInSearchModelArgs();
if (e.Result != null && e.Result.ToList().Count > 0)
{
_stopEventsDataListReturned =
e.Result.Select(dtoStopEvent => new Stop(dtoStopEvent)).ToList();
...
}
else
{
args.Message = "No Data Found";
}
}
Clearly, I have no idea where to start with Rhino,
1) whether I should be using a strictmock or a stub.
2) how to check that a method on the mock was called
3) how to check if the even has been registered
4) how to raise the event
5) how to check if the callback was called.
I find so many different syntaxes in examples using Rhino probably
because of all of the different APIs that have existed over time. I'd
like to be able to use the AAA Syntax if possible but am totally lost
when it comes to how.
thanks much!
