Silk4J provides built-in support for testing Apache Flex applications using Internet Explorer and the Standalone Flash Player, and Adobe AIR applications built with Apache Flex 4 or later.
Silk4J also supports multiple application domains in Apache Flex 3.x and 4.x applications, which enables you to test sub-applications. Silk4J recognizes each sub-application in the locator hierarchy tree as an application tree with the relevant application domain context. At the root level in the locator attribute table, Apache Flex 4.x sub-applications use the SparkApplication class. Apache Flex 3.x sub-applications use the FlexApplication class.
