Subject tool I used testing patches
Date Thu, 18 Aug 2011 17:54:14 GMT
Hi, team.

Sometimes it is tough to reproduce test success or failure since one's
workspace might be tainted.  The following is a process I used to test
a patch running against zookeeper on aws-ec2.  It first creates a
fresh node to perform tests on, then runs the integration test against
zookoeeper.

Here's the steps:

  * preparation
    checkout and mvn install
https://github.com/jclouds/jclouds-examples/tree/master/compute-basics

  * setup a new node with whirr and maven:
    create a m1.small node on aws-ec2 with the following command:
         java -DminRam=1024 -jar
target/compute-basics-jar-with-dependencies.jar aws-ec2 ACCESS SECRET
whirrtest
    setup whirr from a clean svn checkout
         java -jar target/compute-basics-jar-with-dependencies.jar
aws-ec2 ACCESS SECRET whirrtest run /path/to/setup-whirr.sh

  * iterate a patch, testing against a live service
    if you are testing a patch, apply it with the patch-script after
you changed it to use the correct url for the patch you wish to test
         java -jar target/compute-basics-jar-with-dependencies.jar
aws-ec2 ACCESS SECRET whirrtest run /path/to/patch-whirr.sh
    modify test-whirr-service with the config params you want and the
cloud you are testing against and then run it, repeating as necessary
         java -jar target/compute-basics-jar-with-dependencies.jar
aws-ec2 ACCESS SECRET whirrtest run /path/to/test-whirr-service.sh

  * cleanup your node!
     java -jar target/compute-basics-jar-with-dependencies.jar aws-ec2
ACCESS SECRET whirrtest destroy

I hope this helps!
