The difference from the previous version:
FlexUnit 4 Alpha 1 is based on a entirely new source tree. Currently it uses a version of the FlexUnit v.9 graphical test runner for the new framework.
This version is a thorough refactoring of the bottom layer, but V.9 's graphical test runner remains.
Incidentally, there is also an open source Flex/flash function Testing tool Fluorida, interested readers can study (download address: http://code.google.com/p/fluorida/).
The next talk with FlexUnit specific demo, directly understand the FLEXUNIT4 changes.
