I have a flex application written using PureMVC framework.Now,I want to write tests.We are using FlashBuilder 4.Is FlexUnit sufficient for testing? Are there any issues you have faced while writing tests?

What methods do you use to unit test event handlers, particularly if they require information from the event (such as mouse coordinates, or the target of the event)? Is the most common practice to just refactor the behavior into a method that does the lifting while the handler just extracts information from the event, or are there effective ways to simulate event dispatch in FlexUnit or Fluint?
View 1 RepliesI am writing a small flex application that will, eventually, call PHP services to perform its work. In the meantime, however, I would like to have it use local data in XML form to allow me to develop the Flex part independently of the data service.
What is the best way to do this? I want to emulate a service like this:

And invoke the service using issuerService.send(), populating my results as expected. How do I do this as though it were a RemoteObject instead, but keep my data local?

View 3 RepliesI've been trying to setup a working method for unit testing flex libraries using Flex Builder. i have tried setting up a standard flex lib project and using Ant to compile and run the units tests. But this means that when something does go wrong and I want to use the flex builder debugger I cannot do so.
So my next plan is to setup the library as a normal as3/flax/air app as I can use the concept of a main class to run the unit tests. I can then compile the actual library code using Ant.
I could also setup a separate companion project who's sole task is to run units tests on the lib. But this is a little awkward as each library now requires two projects to manage. How do other people develop flex libraries and use unit tests to test/develop/debug the code?
Is it posible to create a partial mock using mockito-flex?

View 2 RepliesMy company is building a Flex application that we may need to port to other platforms:
[Code]...
Currently, I'm looking into application frameworks to build upon and I'm torn between pureMVC and Swiz. I LOVE swiz for its simplicity and how it just gives you a way to hook things up and then apply your own patterns. From a flex-only perspective, this is my 1st choice. But, PureMVC is platform-independent and has already been ported over to most of the platforms that are mentioned above. How valuable is this portability? Will it really make our lives significantly easier when it comes to porting and developing/maintaining multiple applications? If so, then it seems like PureMVC is the way to go.
Alternatively, since Silverlight has the most definite business case for porting of our application, maybe we could port Swiz to Silverlight? I'm not too familiar with which AS3 language and Flex framework features Swiz depends on and whether they are available in C#/Silvelright.
I'm working on an existing modular project that was built in PureMVC. Instead of converting everything over to RobotLegs, I want to create a new module using RobotLegs and plug it into the pureMVC shell. Currently, when the module loads, I get the following flash error: ReferenceError: Error #1065: Variable IMediatorMap is not defined.
Inititally, I thought it was because my module needed a pureMVC Mediator to call the pureMVC StartupCommand to get things "hooked up" and THEN create the RobotLegs' Context. However, that didn't work and I'm still getting the error.
What are the best unit testing frameworks or libraries for AS3 programming? Specifically for projects that do not involve Flex, only Flash.
View 1 RepliesI'm looking for a reliable mocking framework for ActionScript. I've been using mock-as3, but I'm annoyed with what I feel is a hack-ish solution for triggering events. There are other a few other reasons why I'd like to have some options, but not sure if I necessarily need to go into them. I've also looked into Mock4AS, but the interface appears to be cumbersome.
View 3 RepliesI am developing an AS3 application which uses a Singleton class to store Metrics in Arrays. It's a Singleton because I only ever want one instance of this class to be created and it needs to be created from any part of the app. The difficulty comes when I want to unit test this class. I thought adding public getters and setters would enable me to unit test this properly and would be useful for my app. I have read that changing to a Factory pattern will enable unit testing or using Inversion of control. This would of course make it more flexible too. I would like to know of people's thoughts on this matter as there are SO many conflicting opinions on this!

View 1 RepliesI developing an AIR application in Flex that would be dealing with playing different SWFs. I am finding some issues as these SWFs that I am playing are heavy. I find that the animation is not smooth and is causing the graph of CPU usage to go high (my be because single thread architecture of Flex). I am therefore planning to have a multi process architecture for my application. Something like Google Chrome. I have one main application as one process and other SWFs would be playing in separate process but should be seen inside the main application window. How to make it possible in Flex?
View 4 RepliesCanvas.addChild() insists any DisplayObject added implements IUIComponent. But I don't want my core graphics engine dependent on Flex. Is there an obvious/common way around this, to have simple graphical objects like Sprites & Shapes in a Flex application? The individual DisplayObject children I want to add as children represent objects in a game world, like a spaceship or a missile or a horse...
Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.
Could tools like SWFAddress be used in some clever ways to alleviate an existing client-server architecture. I see possibilities to even introduce REST-like pattern mapping or something like that.
What I am currently doing is following all the Cairngorm guidleines, which has already led to a bunch of commands which all make sense, but inclusing the business delegates, and all that stuff, I am getting into a hard time extending and refactoring the application Anyway, what I thought of was somehow reducing the number of application events flying around, and the number of commands responding to them. Actualy, I am quite OK even coupling the view with some logic, if I can get rd of some layer complexity.
What I mean by that: perhaps, I could bind a button click to a url pattern (or use SWFaddress to change the url globally). On the other end, I wll be waiting for changes of the url, reformat it, and pass it onto a service delegate, which has the necessary mappings in mind, so it knows what method to call, or it could even pass the url directly to an HTTPSErvice. The delegate will then deal with the server response, and update the model, which through the bindings will update the view.
I am not going to completely ditch commands. I thing that they are good for scheduling of the internal interactions (within the client itself), but I'd like to abstain from using them for communication with the server.
I am working with a very large number of legacy SWFs written in AS1 and AS2. These SWFs use loadMovieNum extensively.
I am trying to integrate these into a new Air-based app (written in either AS3 or Flex). However, loadMovieNum doesn't seem to work within the Air app.
For example, an AS2 SWF (file1.swf) may try to load another AS2 SWF using:

View 2 RepliesI've just recently learned the PureMVC framework, and am a little confused as to the coupling between Proxy and Mediator objects. The links on this page connect to some documents describing the framework. (Please note, the links on the aforementioned page open PDFs.)
The diagrams and examples of PureMVC I've examined often show a direct coupling between a Mediator and Proxy. When the proxy's state is updated, rather than sending a new Notification, the Mediator (which retrieves a reference to the Proxy from the Facade) has its state updated.
This certainly seems to simplify the logic of the code, but it also directly couples two seemingly disparate components together. To my understanding, a Mediator's purpose is to translate Events from a view into PureMVC Notifications. Proxies are meant to perform some function to gather data and relay it back to the view. These two components seem to exist in different layers of the application, and perhaps shouldn't necessarily be coupled together.
Wouldn't it make more sense to have the Proxy objects send their own Notifications when their state updates, which are forwarded to the interested Mediator by the Facade?
I'm building modular application with 2 modules which share common vo: ShopRegionVO
This vo is also a BlazeDS entity and is mapped to a remote java object. When shell loads first module everything is ok. The second module is a list of ShopRegionVOs and item change is handled with the following code:
sendNotification(CoverageConstants.SET_SELECTED_REGION_COMMAND, ShopRegionVO(List(e.target).selectedItem));

I am building a tabbed interface for switching between various similar layers. Each layer will have a number of graphs. By dragging with the mouse the graphs can be rearranged or even moved between layers. My question is, is it best practice to register a unique mediator for each layer that keeps track of the layers content / organization, or should i keep track of it all with one central mediator.some considerations:
the layer contents and organization will be saved(in a db) so that it can be restored when a user comes back to the app.the layers themselves are functionally identical.the user can add and remove layers at will.
I have one question about pureMvc. I use pureMvc to build an engine, in the engine init part i have an requirement
1) moduleA must init firt
2) moduleB , moduleC need init after moduleA init complate.
3) moduleD need init after moduleB & moduleC init complate.
4) moduleA , moduleB , moduleC , moduleD all extends Proxy beacuse the four system all need to send notifiation ,but no need to listen it.
But to fit for the requirement I can't use command to do it, because they have ini order and also they need to remember current state(ex: moudelB is init Complate but moudleC is not init complete then can't init moudleD) but command is stateless. The best way I think is use one Mediator to do it, beacuse it can both listen and send notification. My question is :
1) Is this a good way to use one Mediator to do it?
2) If use Mediator is good way, then when it hear first moduleA is init complate
registerCommand(FIRST_MODULE_INIT_COMPLATE , initStepTwoCommand);
sendNotification(FIRST_MODULE_INIT_COMPLATE);
removeCommand(FIRST_MODULE_INIT_COMPLATE);
Need to do things like that way or just do the inti logic in the Mediator?
Often multiple instances of the view component would be used in multiple places in an application. Each time I do this, I register the same mediator with a different name. When a notification is dispatched, I attach the name of the mediator to the body of the notification, like so:

I'm looking for suggestions regarding implementing process flow / work flow management in a PureMVC based application. Our Flex application includes a number of processes such as account creation, payment processing, etc. Within our team, there is some discussion of how rigidly we should adhere to the PureMVC model. Within the PureMVC model, it seems reasonable that the current state in the process could be managed in a Proxy. Commands are clearly responsible for processing the actions required of each node and for node transitions. Mediators for managing the UI.
However, I think that there is an important bit still missing here: a ProcessController. The approaches we've reviewed all seem to either violate the PureMVC model (even just slightly) or make unreadable code. A proxy would maintain the state of the process. As such, it seems to be an appropriate way to implement the controller. However, this is putting a lot of business logic into the proxy.

I was wondering best practices for views of inherited classes in PureMVC in this situation: Multiple classes inherit a BaseClass (lets say InheritedClass1 and InheritedClass2) Each InheritedClass has a respective view (derived from a base view class, but each unique) With a given dataset (lets say ArrayCollection of InheritedClass1/2 Objects), the respective views need to be dynamically loaded. The dataset is relatively large, so a TileList would be nice (since it only instantiates objects which are currently displayed) I can think of a couple solutions, but I find them to be too "hackish" to be the best solution:
In View: Repeater over a BaseClassView which attributes a view to a State (set to the "InheritedClass1" state to add a InheritedClass1 object) Pros: No unneeded memory increase (States' objects are instantiated when needed) Cons: View is dependent on the data types, so adds coupling In Mediator: Loop over the ArrayCollection and addChild() the views based on data type Pros: Works. Cons: Mediator is adding things to the View, which defeats the point of the separation of Mediator and View. Slower than a Repeater.
I'm working on a general code library for ActionScript 3.0 called as3lib which includes several extensions to the core API and some useful functions. I've written several unit tests (using FlexUnit) to make sure everything is working correctly.
What is the best way to organize these tests in the library? Currently, I have all my code in src/ and my tests in test/ but I've set up a secondary Flex project to run the unit tests. I am also manually adding and removing the test files from the library when I want to run the tests.
Preferably one where the compiled library doesn't include the test files but I don't need two separate projects to test them.
