Flexmojos is a convenient tool used to compile and test flex applications. However, when running unittests in headless linux with Hudson, I met a problem caused by cookies. The server side needs cookies to make sure requests are valid. I googled a lot and find such a solution finally.

1. you are required to install xvfb according the instructions in this article.
2. you must have firefox 3.x.x installed.
3. navigate to “about:config” in firefox and set “dom.allow_scripts_to_close_windows” to “true”;
4. register executions for flexmojos-maven-plugin like this:

   <executions>
   	<execution>
   		<id>default-test-compile</id>
   		<configuration>
   			<useNetwork>false</useNetwork>
   		</configuration>
   	</execution>
   
   	<execution>
   		<id>default-test-run</id>
   		<configuration>
   			<flashPlayerCommand>firefox</flashPlayerCommand>
   		</configuration>
   	</execution>
   </executions>

5. download proper SWC according to the flexmojos version here. For example, I am using flexmojos 3.5.0, so I choose to download flexmojos-unittest-support-3.5.0.swc.
6. checkout source code of flex-unittests-support with svn here.
7. create a flex library project with flex(flash) builder called “flexmojos-unittest-support”, a sample project you can find here.

     flexmojos-unittest-support.rar (40.6 KiB, 106 hits)

8. modify function exitFP defined in class org.sonatype.flexmojos.unitestingsupport.ControlSocket:

   		private function exitFP( event:* ):void
   		{
   			//Exiting
   			trace("Exiting");
   			if(ExternalInterface.available)
   			{
   				var functionStr:String = "function()" +
   					"{" +
   						"window.opener=null;" +
   						"window.open('','_self');" +
   						"window.close();" +
   					"}";
   
   				ExternalInterface.call(functionStr);
   			}
   			else
   			{
   				fscommand("quit");
   			}
   		}

9. add flexmojos-unittests-support-x.x.x.swc as a library of this project.
10. compile and build flexmojos-unittest-support.swc.
11. install flexmojos-unittest-support.swc into maven repository according to the version of the flexmojos being used. For example, I am using flexmojos-3.5.0, so I run the command below under the bin directory of the flex library project:

    mvn install:install-file -DgroupId=org.sonatype.flexmojos -DartifactId=flexmojos-unittest-support
    -Dversion=3.5.0 -Dpackaging=swc -Dfile=flexmojos-unittest-support.swc -DcreateChecksum=true

12. now, you can run unittests with hudson supporting cookies.

NOTE: The javascript code used to close the browser can work with firefox, can not work with IE8. I do not test the other browsers.
