=== How basic validation works ===

*CRAB validation is twofold in the sense that you have client and server parts.
*Keeping in touch with the integration and development teams, you will learn for each new client release on which servers it has to be tested.
*In fact, there exists servers dedicated for tests and where the latest pre-release version of CRABSERVER (CS) is installed.

*Each new release is announced on the "CRAB development" Hypernews forum and it is installed at CERN in /afs/cern.ch/cms/ccs/wm/scripts/Crab/.
*If you want to test it from IIHE T2, you just have to follow the installation procedure described [[InstallingCRAB| here]].

*Basic validation means that only the basic features are to be tested.
*You will find on this [https://twiki.cern.ch/twiki/bin/view/CMS/ValidationofCRABclientreleases page] more details on what is to be tested.
*On this, you will see that each release is checked in three different ways : standalone (no CS), with CS+glite, and with CS+glidein.
*This page is also where results of validation tests are to be collected.
*It is important to update it and to inform the development team about the results after each validation campaign.

=== The validation framework ===
To avoid repetitive tasks during the validation, a framework is being developed. The goal of this framework is to check all the basic CRAB commands in a single run.

If you want to try this, follow these steps :

#Check out the project :
<pre>
cvs co COMP/INTEGRATION/crabvalidation
</pre>
Note : if working from a UI at IIHE, you must set up your CVS environment as described [[Access_to_CERN_CVS| here]].
2. Unpack and build the project :
<pre>
cmsrel CMSSW_X_Y_Z
cp COMP/INTEGRATION/crabvalidation/* ./CMSSW_X_Y_Z/src/
cd ./CMSSW_X_Y_Z/src
tar xvzf CMSSW-Demo.tgz
cd ./Demo/DemoAnalyzer/
scram b
cd ../..
</pre>
Remark: In case you want to test the 64bit you have to set
<pre>
export SCRAM_ARCH=slc5_amd64_gcc434
export LD_LIBRARY_PATH=/lib64:$LD_LIBRARY_PATH
</pre>
3. Adapt the crab.cfg (at least change the SE).
4. Do what you usually do before submitting jobs with CRAB. At IIHE, it looks like that :
<pre>
source $VO_CMS_SW_DIR/cmsset_default.sh
cmsenv
source /user/cmssoft/crab/CRAB_2_7_4_pre2/crab.sh
</pre>
5. Run the validation script :
<pre>
./RunValidationTest.py -server slc5ucsd -scheduler glite
</pre>
In this example, we are testing CRAB client 2_7_4_pre2 on the CRABSERVER slc5ucsd with glite as scheduler. More info on the Release validation suite can be found here [https://twiki.cern.ch/twiki/bin/view/CMS/IntegrationDistributedComputingCRABVal here].
Some of the commands to be run
<pre>
./RunValidation.py -printToFile standaloneglite
./RunValidation.py -server slc5cern -printToFile serverglite
./RunValidation.py -server slc5cern -scheduler glidein -printToFile serverglidein
./RunValidation.py -printToFile standaloneglite -checkResubmission
./RunValidation.py -server slc5cern -printToFile serverglite -checkResubmission
./RunValidation.py -server slc5cern -scheduler glidein -printToFile serverglidein -checkResubmission
</pre>

=== Re-using the validation framework to test the locally adapted CRAB for PBS submission ===

*Example configuration files, based on the validation suite above, can be here:
<pre>
/localgrid/jmmaes/CrabPbsSubmissiontest/CMSSW_3_10_0/src
</pre>
