+
+To set up S3P test environment with all docker images, either build the docker images locally with
+"mvn clean install -P docker" in clamp/packages directory Or use policy/docker/csit to bring up docker images.
+
+Important Instructions to setup environment using CSIT:
+-------------------------------------------------------
+Step 1: $cd policy/docker/csit
+
+Step 2:
+$vi run-project-csit.sh
+Comment the on_exit cleanup function call in run-project-csit.sh file. By doing this, docker images once started will not be shutdown.
+All images will be up and running, to carryout any Stability or Performance tests using JMeter.
+# ensure that teardown and other finalizing steps are always executed
+#trap on_exit EXIT
+
+Step 3:
+./run-project-csit.sh clamp
+This command will bring up all required docker images
+
+Step 4: Ensure the IP's and Ports in stability.jmx and performance.jmx are changed, and reflecting to the IP's of docker images.
+Example:
+$cd ./clamp/testsuites/stability/src/main/resources/testplans/stability.jmx
+          <elementProp name="RUNTIME_HOST" elementType="Argument">
+            <stringProp name="Argument.name">RUNTIME_HOST</stringProp>
+            <stringProp name="Argument.value">192.168.48.9</stringProp>
+            <stringProp name="Argument.metadata">=</stringProp>
+          </elementProp>
+
+
+On successfull docker image bring up:
+------------------------------------
+$docker ps

+To start performance tests:
+--------------------------
+nohup ./jMeter/apache-jmeter-5.2.1/bin/jmeter -n -t performance.jmx -l testresults.jtl
+
+To start stability tests:
+--------------------------
+nohup ./jMeter/apache-jmeter-5.2.1/bin/jmeter -n -t stability.jmx -l testresults.jtl
+
+To remove all docker images after Stability (72hrs) and Performance(2hrs) test runs:
+-----------------------------------------------------------------------------------
+cd policy/docker/csit
+docker-compose -f ./docker-compose-all.yml down -v
