Running selenium on a headless EC2 machine?

Question

I have a headless EC2 M1.Small instance running Ubuntu. I have been trying to use it to run a selenium test coded in Ruby. I am running selenium server 2.0b3 (the latest).

i have enabled XVFB:

$ sudo startx -- which Xvfb :1 -screen 0 1024x768x24 2>&1 >/dev/null & [1] 1119

$ DISPLAY=:1 java -jar Automation/ruby-selenium-framework/selenium-server-1.0.3/selenium-server.jar > /tmp/selenium_log.log & [2] 1245

And then run my code:

$ ./BTRuby.rb coverage_

I get the following output to the selenium log:

14:11:27.448 INFO - Command request: getNewBrowserSession[*firefox, URL, , ] on session null
14:11:27.448 INFO - creating new remote session

14:11:36.007 INFO - Command request: open[URL, ] on session 4b1395b136174ab798eddd6a59d8e308

Can anyone provide any help? It just seems to hang at this last INFO line.

BTW, the URL variable is a valid URL that I have stripped out for purposes of this question

Answer 1

sudo startx -- which Xvfb :1 -screen 0 1024x768x24 2>&1 >/dev/null &

DISPLAY=:1 java -jar selenium-server-1.0.3/selenium-server.jar > /tmp/selenium_log.log &

was able to do the trick
