  • Current activity of the tests can be viewed by attaching to a screen session running under the tinderbox user. There's two sessions, one for QA tests (named qa) and one for all the other tests (named tbox). Use commands screen -r qa or screen -r tbox to attach.
  • Selenium Server v2.37.0, Test::WWW::Selenium Perl module v1.24 and Firefox v24 are used by the QA tests. Be careful when updating these so that the trees won't burn unnecessarily.
  • Selenium Server is manually installed to the /usr/local/share/selenium-server/ directory. Scripts to start it and to list related processes are in the /usr/local/bin/ directory.
  • Firefox at /usr/lib64/firefox/firefox is referenced from Selenium start scripts and is installed from standard RHEL repositories.
  • The perl-Test-WWW-Selenium package is installed/updated from Repoforge (previously known as RPMforge) but is excluded from normal yum updates so it needs to be manually updated (use yum update --disableexcludes=rpmforge perl-Test-WWW-Selenium command) when needed.
  • Replicates bugs_tip, bugs_bugzilla4_4_branch, bugs_bugzilla4_2_branch and bugs_bugzilla4_0_branch databases from landfill to be used in the checksetup update testing.
