I have seen various postings about integration between FlexUnit with Ant, however most solutions seem to require a Flex server. My motivation here was to create an Ant task that has no dependency on a server. That would allow unit tests to be run in autonomously.

...

My solution is comprised of a controlling Ant task, flexunit, and a FlexUnit test runner, JUnitTestRunner, which is shown in the diagram below. The flexunit task starts a socket server running inside of a thread and launches the Flash Player, which runs the tests using the JUnitTestRunner. When JUnitTestRunner has finished running the test it formats the results as per the JUnit XML format and sends them to the flexunit task over an XML Socket, the flexunit task then saves them to disk. We can then use the JUnitReport task to create a report or use CruiseControl to create a report.
