Problem

: Some of us encounter the Flex unit runtime issue when running the flex unit in the flash builder a few days ago, and it blocked our running the unit test without the ant script.

Error: Skin for FlexUnitApplication cannot be found.

Summary

: It is a issue of the Flex Unit framework, not relative to our test cases. I guess it was caused by the Flash Player version upgrade.

Solution

: If you encounter this exception again, you can modify the file FlexUnitApplication.mxml manually as following (which should be created by flex unit and not need to modify before)

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" xmlns:flexui="flexunit.flexui.*" creationComplete="onCreationComplete()" skinClass="spark.skins.spark.ApplicationSkin" >
