Setup of flex units on linux

Question

I am working on a project using Flex and until now we are using Windows to run flex unit tests for the modules/artifacts that require flex environment. Because of given dependencies, it is difficult to automatize anything because I have to swithch between linux/windows when running those maven tests.

I have made an effort to try to make flex units tests run on linux, but have not succedded [yet]. Here is small part of the stack trace from maven clean test -X on a flex project.

I need help find out what is wrong. If any of you guys know any other way to run flex units test on linux, NOT THROUGH JENKINS/HUDSON, I will be extremely grateful.

Are you running an X client? It seems you are running with root, maybe if you were working with another user it would create a more specific Xauthority. — poussma, Jan 07 '13 at 10:29
@ZNK-M Yes, as you see I am using xvfb and have installed xvfb-run under /usr/local/bin, and it seems like the flexmojos plugin picks that up fine, but stil something else that is going on. The reason I am running with root is because I am on sandbox testserver, so afraid of nothing :-). I could try to run with another user. — Gogi, Jan 07 '13 at 10:35
Yes, maybe. I am wondering if the Xauthority generated by the root user has a special behaviour — poussma, Jan 07 '13 at 11:26
I found out that the problem is the xvfb-run script and you can see the error under "[DEBUG] [SYSERR]: mktemp: cannot create temp file /tmp/Xauthority: File exists". I tried removing everything from /tmp and rerun the test, and voila everything ok. So I think I'll have to modify the script to place the Xauthority file in another random directory under /tmp so it's not using the same place every time. — Gogi, Jan 07 '13 at 11:39

First of all, just follow the linux part of the instructions on the following site:Running unit tests - FlexMojos. Download the flashplayer and untar it some appropriate place and put the absolute directory path in your PATH variable.

Download the xvfb-run script and change the following 'fi'

# If the user did not specify an X authorization file to use, set up a temporary
# directory to house one.
if [ -z "$AUTHFILE" ]; then
  XVFB_RUN_TMPDIR="${TMPDIR:-/tmp}/$PROGNAME.$$"
  if ! mkdir -p -m 700 "$XVFB_RUN_TMPDIR"; then
    error "temporary directory $XVFB_RUN_TMPDIR already exists"
    exit 4
  fi
  AUTHFILE=$(mktemp -p "$XVFB_RUN_TMPDIR" Xauthority)
fi

to

# If the user did not specify an X authorization file to use, set up a temporary
# directory to house one.
if [ -z "$AUTHFILE" ]; then
   XVFB_RUN_TMPDIR=$(mktemp -d)
   if ! mkdir -p -m 700 "$XVFB_RUN_TMPDIR"; then
     error "temporary directory $XVFB_RUN_TMPDIR already exists"
     exit 4
   fi
   AUTHFILE=$(mktemp "$XVFB_RUN_TMPDIR/Xauthority")
 fi

I solved my problem, hopefully you will too. Good luck.
