FlexUnit with all AS3 AIR doesn't work?

I have recently been trying to take a stab at TDD (Test Driven Development), that I'm sure many of you are familiar with.  To that end I have been trying to use FlexUnit 4 from within Flash Builder 4. 


If I create a project as follows:

  1. New --> Flex Project
  2. Next, Next
  3. (Main Application File) Replace .mxml with .as
  4. Finish

Then when I try to use FlexUnit in the ordinary manner, it fails to generates a proper FlexUnitApplication.mxml file.  This is the contents of that file:


<!-- This is an auto generated file and is not intended for modification. -->



Consequently, there is a compile error that I can't get around:

Content is not allowed in prolog.




If I follow the same process as above, without changing the .mxml to .as then the tests run properly. 


Things I have tried to get around the error:

  • Updating FlexUnit to 4.1
  • Pressing Refresh in the FlexUnitsResults window
  • Creating a project with .mxml, and subsequently deleting that mxml and replacing it with an actionscript class
  • Pounding on my desk.

None of these have worked.


Is anyone here successful using FlexUnit with FlashBuilder 4 for an all AS3 AIR project?  Alternatively, can anyone suggest an alternative Test package?

Re: FlexUnit with all AS3 AIR doesn't work?

I found an at least temporary solution.  I restarted FlashBuilder, and compiled despite the marked error under Problems and it worked. 


I think restarting Flashbuilder maybe clears it of a previously stored properly compiled build.  (Maybe Clean could also do this?).  Anyways, at compile time, the mxml file was properly generated and all is well.
