As promised, I’ve updated the code from the August presentation with a working version of the MockAs3TestRunner class for FlexUnit4. You can find the latest incarnation in the Adogo SVN. I’ve also bundled, what will probably be, beta version 2 of FlexUnit 4 with the project in swc form (built from the latest 4.x branch) if you can’t wait for the eminent release. If you’d like more details on how to use the runner, check out my most recent blog post for more details.
