AsUnit is an Open-Source, Unit Test Framework for Macromedia Flash ActionScript 2.0 and 3.0. AsUnit 2.x is fully integrated with the Flash IDE, and there is a Mozilla XUL UI that works alongside any other ActionScript authoring tools.
AsUnit is the only open source unit test framework that supports ActionScript 2.0 and 3.0 development without binding you to any particular development tools!
AsUnit works with ALL ActionScript development environments, including Flash MX 2004, Flash 8, TextPad, Sepy, X-Code, ASDT, FDT, Flex Builder 1.0/1.5 and even Flex Builder 2.0 (alpha), MTASC, and Central. This framework allows developers to easily create and manage Classes, Test Cases, Test Suites and view the results of extensive test fixtures.
