What are we talking about?
Wikipedia says:... test automation is the use of special
software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes to predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or add additional testing that would be difficult to perform manually ...
Why should you bother?
● Efficiency
● More complete error reports
● Huge time savings
● A more complete code coverage
Why did we bother?
While taking over an existing project
● Huge and complicated code base
● No existing unit tests
● Complaints by users:○ a lot of bugs in the GUI
○ a lot of recurrent bugs
How did we start?
External testing tool
SeleniumA suite of tools to automate your web browser.
External Interfacecommunication between your browser and the Flash Player.
● Java Test○ Selenium for Java
○ Standalone Selenium server
○ FlexiumLink and FlashSelenium
● Flex Application○ Flexium

The Selenium setup
DEMO
public Boolean click(String objectId) throws Exception {
delay();
if(isReady()) {
String result = call("doFlexClick", objectId, "");
return checkResult(result);
}
return false;
}
Under the hood - Selenium (1)
public Boolean click(String objectId) throws Exception {
delay(); if(isReady()) {
String result = call("doFlexClick", objectId, "");
return checkResult(result);
}
return false;
}

if(isReady()) { String result = call("doFlexClick", objectId, "");

}

● Flexium ○ Compiles into your application
○ Parsing of your applications Stage
○ Registers your (custom) commands
Under the hood - Apache Flex (1)
Compiles into your application
... separate from the software being tested...
1) Use a Mixin
... [Mixin]
public class Flexium extends Sprite {...
Under the hood - Apache Flex (2)
Compiles into your application
... separate from the software being tested...
2) Include library
include-libraries library [...]

Parsing of your applications stage
Every component that gets added to the stage will be parsed by the
AS3-commons Stage Processing Library
http://as3commons.org/as3-commons-stageprocessing/index.html
Under the hood - Apache Flex (3)
Parsing of your applications stage with AS3Commonsprivate var _registry:FlashStageObjectProcessorRegistry;
private function initProcessor():void {
_registry = new FlashStageObjectProcessorRegistry();
_registry.useStageDestroyers = true;
_registry.registerStageObjectProcessor(
new EventDispatchingObjectProcessor(this),
new EventDispatchingObjectSelector()
);
_registry.initialize();
}

FYI● working with data
○ mock data
■ same result on every test
■ same result on every system
What's next?● My way, not the highway...
● Custom components - custom commands
