I used the checkbox-unity survey to test beta unity 5.0 in Precice.
Completing the survey took me a couple of hours because I thoroughly described the problems I discovered. At the end of the survey I didn't notice that there was a text-field to enter the launchpad login detail and clicked next. An error prompted that sending of the info failed, giving me no option to enter my login-detail and retrying. Clicking 'Previous' regenerated the results and got me back to the login-details. filling my login (no password prompt) and Clicking next displayed 'successful' (within a hundred of a second) but I have the feeling noting has been send.
Is there a way to verify successful submission? I still have the results in a submission.xml file but relaunching checkbox-unity again starts the survey all over again.
I hoped my contribution would be helpful, but if the report isn't submitted, it is useless and disappointing. I found out about the test via http://www.omgubuntu.co.uk/2012/01/unity-5-0-ready-for-testing/
