Build and run FlexUnit from the command line - command-line

Question

I am building an app using ActionScript3 with Flash Builder 4 as my IDE.
The IDE supports a unit testing framework called "FlexUnit".
I can build and run tests within the IDE, no problem.
After much pain and suffering I figured out how to build the unit tests as a swf from the command line. I can point a browser or flash player at the swf and the tests run.
But for an automated build system this is no good: I would like to build the tests, run them, and collect/analyze the results to tell which tests, if any, are failing.
I can imaging some hackery: hack FlexUnit base libraries to dump output to stderr instead of just to the IDE console. Hack some script together that points a browser at the swf, counts to 60, kills the browser and checks stderr.
But that's hideous.
I have to believe there's some way to build and run from the command line that works nicely with automated build systems.
Further complication: I am a relative noob with ActionScript (~1 month). My background is C++, makefiles, etc. All the stuff I had to do to get the tests even to build outside the ide (a build.xml file, ant) was complete greek to me, just cut n pasting from examples I could find.

As far as I'm aware your only options for running the swf are in the browser or in the standalone player. Running in the player should not be a problem for your continuous integration environment as long as you can get at the test results and exit the application.
To print test results to stdout you need to add a Text listener to your testunit core instance.
core.addListener( TextListener.getDefaultTextListener( LogEventLevel.DEBUG ) );
To exit the application after the tests have run...
System.exit(0);
For example, your top level mxml file might look like this...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="runMe()"
xmlns:adobe="http://www.adobe.com/2009/flexUnitUIRunner"
>
<mx:Script>
<![CDATA[
import org.flexunit.runner.FlexUnitCore;
//import org.flexunit.listeners.UIListener;
//import org.flexunit.listeners.CIListener;
import org.flexunit.internals.TextListener;
import mx.logging.LogEventLevel;
import flash.system.System
import unit_tests.TestAuthentication.TestAuthentication
private var core:FlexUnitCore;
public function runMe():void {
core = new FlexUnitCore();
//core.addListener(new UIListener(uiListener));
//core.addListener(new CIListener());
core.addListener( TextListener.getDefaultTextListener( LogEventLevel.DEBUG ) );
core.run( TestAuthentication );
System.exit(0);
}
]]>
</mx:Script>
</mx:Application>
Then all you need to do is parse the output.
It's not as elegant as we might like but it should work.
