I wanted to see if there was a known issue with FlexUnit4.1 RC2 when running AIR based tests with the "air" player option.
What I am seeing is that adl.exe launches a window, and the display says it is running tests, but no tests are ever executed. The window stays open forever until I kill it manually. The interesting thing is that I can run adl.exe from the command line using the same arguments FlexUnit says it is using, and the runner window will appear and the tests will run. I cannot imagine what the difference is between the Ant task running adl.exe and my running it from the command line.
Here is the setup.
Here is the log output:

At this point, adl.exe launches but no tests run, and I have to kill the window.
Thanks in advance...
Are you referring to the MXML TestRunner file, or to the flexUnitDescriptor.xml file?
BTW, we are having some IT issues and all the Flex builds are broken, so it may be Monday before I can try out the RC3 FlexUnit binaries.
I am sorry, but today I can no longer reproduce this issue. I have used both 4.1RC2 and 4.1RC3 and both of them launch an adl.exe (AIR 2.0.2) that executes my tests. Perhaps my SWCs were corrupted and got fixed by the nightly builds? Anyway, sorry for the noise. Thanks for the offer of help.
