• Set database access permissions runing on CE:

      mysql -h $CE_HOST -u root --password="$MYSQL_PASSWORD"  -e "GRANT ALL PRIVILEGES to $CREAMDB_USER@'<FQDN_UI_HOST>' IDENTIFIED BY '$CREAMDB_PASSWORD' WITH GRANT OPTION";
      

CREAM regression, BLAH functionality and regression testsuites installation, configuration and use

• Test if the setup is correct. You must be able to copy or to connect to the CREAM CE from the EMI UI without supplying passwd.

here

yum install cream_blah_testsuites-X.Y-Z.noarch.rpm 

Tha manual procedure is the standard procedure to grant ssh key access in linux:

• From EMI UI where testsuites are installed create an ssh rsa key pair for host validation, here's how:

       my-ui:~# ssh-keygen -t rsa
     

• Now you need to copy the public key to the CREAM CE to be tested (do NOT copy the private key), obviously use scp to do this

       my-ui:~# scp ~/.ssh/id_rsa.pub my-ce:~
     

• Connect to the CREAM CE (my-ce):

       my-ui:~# ssh root@my-ce
     

• Check out .ssh stuff, if .ssh dir doesn't exist you need to create it

       my-ce ~ # ls -la ~/.ssh
       ls: cannot access /root/.ssh: No such file or directory
       my-ce ~ # mkdir .ssh
       my-ce ~ # chmod 700 .ssh
     

• Now copy your ssh public key into authorized keys file and delete it when finished:

       my-ce ~ # cat ~/id_rsa.pub >> .ssh/authorized_keys
       my-ce ~ # chmod 600 .ssh/authorized_keys
       my-ce ~ # rm id_rsa.pub
     

• Test if the setup is correct. You must be able to copy or to connect to the CREAM CE from the EMI UI without supplying passwd:

Note:

Sometimes additional configurations are requested on remote ssh daemon, this may vary from basic security configuration. If final test failed you probably have PublicAuthentication or RSA disabled. In this case you need to change them (it doesn't affect or lower your current security). Tipically this change is done by editing /etc/ssh/sshd_config file or better (for security) the user-specific ~/.ssh/config. To get the correct configuration, see that the following attributes are set (not commented or set to "no") in your sshd_config or ~/.ssh/config file RSAAuthentication yes PubkeyAuthentication yes

If you change sshd_config file with these values you need to restart ssh daemon (/etc/init.d/sshd restart)

/opt/cream_test/lib/vars.py

• Create the cream_blah testsuites configuration file:

Versions compatibility

• cream_blah_testsuite-0.1-0 is tested with cream_test-1.8.el5-1 and python 2.6

• install a emi user interface
• create your user
• install your user certificate
• test your EMI UI with a simple job submission.

EMI UI installation and configuration instructions are available here.

• install cream_test testsuite.

cream_test testsuite installation, configuration and use instructions are available here.

here

• At first create a user proxy:

      voms-proxy-init -voms <VO>
      

• Caveats:

Run BLAH testsuites

• Run BLAH regression tests for cream configured with old blparser

   pybot -i old_parser /opt/cream_blah_testsuites/testsuites/blah_regression/tests/bug_*.html

• Run all BLAH regression tests for cream configured with new blparser

   pybot -i new_parser /opt/cream_blah_testsuites/testsuites/blah_regression/tests/bug_*.html

• Run BLAH regression tests for a specific release, ex. blah 1.18.0

   pybot -i blah_1.18.0 /opt/cream_blah_testsuites/testsuites/blah_regression/tests/bug_*.html

• To switch from old to new blparser you have to:
  • Go to the cream ce, set

    BLPARSER_WITH_UPDATER_NOTIFIER=true

    in

    <site_info_dir>/services/glite-creamce

    and reconfigure using yaim.
  • In file /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini set in section [blah_specific]:

            parser_type = with_updater_notifier
            parser_log_file = /var/log/cream/glite-ce-bnotifier.log
            

• To switch from new to old blparser you have to:
  • Go to the cream ce, set

    BLPARSER_WITH_UPDATER_NOTIFIER=false

    in

    <site_info_dir>/services/glite-creamce

    and reconfigure using yaim.
  • In file /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini set in section [blah_specific]:

            parser_type = with_blparser_only
            parser_log_file = /var/log/cream/glite-lsfparser.log
            

Run CREAM regression testsuite

• Run all CREAM regression tests

   pybot  /opt/cream_blah_testsuites/testsuites/cream_regression/tests/bug_*.html

• Run CREAM regression tests for a specific release, ex. cream 1.14

   pybot -i cream_1.14 /opt/cream_blah_testsuites/testsuites/cream_regression/tests/bug_*.html

• Create (as root user) the cream_blah testsuites configuration file:

       cp /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini.template /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini
     

  and customize it. Be careful:
  • Set the right middleware version installed in the ce under test
  • Set the right path of the yaim configuration files (site-info-path) and be sure they are editable
  • Check the blah_parser parameter value. It must be adequate to the blparser version (old or new) and batch system
• In the user shell you will use to launch tests source the file: /opt/cream_blah_testsuites/testsuite_env.sh

       source /opt/cream_blah_testsuites/testsuite_env.sh 
     

  It will setup the environment needed to run the testsuites.
• Set python4 pythonpath doing:

     export PYTHONPATH=/usr/lib/python2.4/site-packages:$PYTHONPATH
     

here

• Run BLAH functionality testsuite:

   pybot /opt/cream_blah_testsuites/testsuites/blah_testing/tests

• Run BLAH functionality tests one by one:

   pybot /opt/cream_blah_testsuites/testsuites/blah_testing/tests/check_notifications_for_normally_finished_jobs.html
   pybot /opt/cream_blah_testsuites/testsuites/blah_testing/tests/check_notifications_for_cancelled_jobs.html
   pybot /opt/cream_blah_testsuites/testsuites/blah_testing/tests/check_notifications_for_suspended_resumed_jobs.html

Remember: to switch from new to old blparser or vice versa you have to do two things:

Caveats:

• lauch the testsuites in a shell where you have write permissions: robot fremework tryes to write log files in the path where it is launched and it fails if it is unable to create its logs.

• All cream and blah testsuites (functionality and regression) work "over" a EMI User Interface, so for first install it, create your user, install your user certificates and test your EMI UI with a simple job submission. EMI UI installation and configuration instructions are available here.
• cream_blah_testsuites depend from cream_test testsuite, whose installation, configuration and use instructions are available here.
