Re: [Asunit-users] Testing Event Driven Architecture

[Ian T. <Ia...@mo...>]

Are you wanting to test a custom visual component, or is it that your
class under test uses a visual component?

If you give me a bit more context then I could probably put together an
example.

 

It's important to understand that ASUnit is a unit testing framework,
not an integration testing framework.

It is designed to help verify behavior of a single unit of functionality
in your application, typically at single class/method level.

 

It's not really appropriate if you want to test the end-to-end
functionality of your application.

 

If you want to verify that when a user clicks a button a request is made
to the server, this would be an integration test.

 

You could however write several unit tests that cover the individual
components involved in the above scenario:

*         A test to verify that when a user clicks your button class a
click event is dispatched.

*         A test to verify that the consumer of your button event
performs a particular action (e.g. invoking a service).

*         A test to verify that a particular service call makes a
request with particular parameters.

 

Testing visual components has it's own challenges as you are usually
bound to concrete dependencies (flash core classes, library assets),
flash 8 made it more feasible technically to verify visual states (using
BitmapData) but I would be very clear about what I'm wanting to test and
whether ASUnit can actually help me achieve this.

 

I'm happy to help you with a specific example, but it's a bit difficult
to give you an abstract example that would actually be useful.

 

Thanks,

 

Ian

I am in the same boat as Mudit - but am sure once I see a working
example of unit testing on a traditional component (i.e. a SimpleButton)
that changes a state or a value when pressed, and then changes it back
when pressed again - this will give me something to work with.

Hi Mudit,

Do you have an example of what you're trying to test?

The ease of testing will be based on how interdependent the components
of your architecture are. You should be aiming to reduce dependency on
concrete implementations (using interfaces and abstract classes).

If you are happy to post an example of what you're having difficulty
with, I can try to help.

Thanks,

Ian

I am new to AsUnit, and I followed few tutorials on how to unit test.
But I am somewhat confused on how to unit test with AsUnit an Event
based architecture !
