+# CORD TESTER
+The CORD Automated Tester Suite is an extensible end-to-end system test suite targeting CORD PODs. 
+Here we set it up for single-node CORD .
+
+# Setting up CORD tester for a single-node CORD environment
+* Details can be found at:
+* `https://github.com/open-cloud/openstack-cluster-setup`
+
+# Get started
+* `wget https://raw.githubusercontent.com/open-cloud/openstack-cluster-setup/master/scripts/single-node-pod.sh`
+* `bash single-node-pod.sh [-t] [-e]`
+  * With no options, the script installs the OpenStack services and a simulated fabric. It creates VMs for
+    XOS and ONOS but does not start these services.
+  * Adding the `-t` option will start XOS, bring up a vSG, install a test client, and run a simple E2E test.
+  * Adding the `-e` option will add the [ExampleService](http://guide.xosproject.org/devguide/exampleservice/) 
+    to XOS (and test it if `-t` is also specified).

+
+```bash
+$ git clone https://github.com/opencord/cord-tester.git
+$ cd cord-tester/src/test/setup/
+
+$ sudo ./cord-test.py -h
+usage: cord-test.py [-h] {run,list,build,cleanup} ...
+
+Cord Tester
+
+positional arguments:
+  {run,list,build,cleanup}
+    run                 Run cord tester
+    list                List test cases
+    build               Build cord test container images
+    cleanup             Cleanup test containers
+
+optional arguments:
+  -h, --help            show this help message and exit
+
+$ sudo ./cord-test.py run -h
+usage: cord-test.py run [-h] [-t TEST_TYPE] [-o ONOS] [-r] [-q] [-a APP] [-p]
+                        [-e TEST_CONTROLLER] [-k] [-s]
+                        [-u {test,quagga,radius,all}]
+optional arguments:
+  -h, --help            show this help message and exit
+  -t TEST_TYPE, --test-type TEST_TYPE
+                        Specify test type or test case to run
+  -o ONOS, --onos ONOS  ONOS container image
+  -q, --quagga          Provision quagga container for vrouter
+  -a APP, --app APP     Cord ONOS app filename
+  -p, --olt             Use OLT config
+  -e TEST_CONTROLLER, --test-controller TEST_CONTROLLER
+                        External test controller ip for Onos and/or radius
+                        server. Eg: 10.0.0.2/10.0.0.3 to specify ONOS and
+                        Radius ip to connect
+  -r SERVER, --server SERVER
+                        ip:port address to connect for cord test server for
+                        container requests
+  -k, --keep            Keep test container after tests
+  -s, --start-switch    Start OVS when running under OLT config
+  -u {test,quagga,radius,all}, --update {test,quagga,radius,all}
+                        Update cord tester container images. Eg:
+                        --update=quagga to rebuild quagga image.
+                        --update=radius to rebuild radius server image.
+                        --update=test to rebuild cord test image.(Default)
+                        --update=all to rebuild all cord tester images.
+  -n NUM_CONTAINERS, --num-containers NUM_CONTAINERS
+                        Specify number of test containers to spawn for tests
+
+$  sudo ./cord-test.py list -h
+usage: cord-test.py list [-h] [-t TEST]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -t TEST, --test TEST  Specify test type to list test cases. Eg: -t tls to
+                        list tls test cases. -t tls-dhcp-vrouter to list
+                        tls,dhcp and vrouter test cases. -t all to list all
+                        test cases.
+ sudo ./cord-test.py build -h
+usage: cord-test.py build [-h] {quagga,radius,test,all}
+
+positional arguments:
+  {quagga,radius,test,all}
+
+optional arguments:
+  -h, --help            show this help message and exit
+
+## Setup prerequisites
+$ sudo ./prerequisites.sh --cord
+
+## Build container images
+$ sudo ./cord-test.py build test
+
+## Initiate a setup for test
+$ sudo ./cord-test.py setup --olt -e 192.168.122.110/172.17.0.2
+
+192.168.122.110 : ONOS running on compute node 192.168.122.110
+172.17.0.2 : ONOS accessible radius server.
+
+## Once above steps are done
+$ sudo docker attach cord-tester1
+$ cd /root/test/src/test/cordSubscriber
+$ nosetests -v cordSubscriberTest.py
+
+```
+This would run a CORD Subscriber channel surfing tests and do a get to google.com.
+Channel jump test does channel surfing by joining/leaving random channels and validation .
+```
+```
+olt_config.json specifies the subscriber and test container configuration.
+```
+* For cleanup
+```
+$ sudo ./cord-test.py cleanup --olt
+```
+```
+$ sudo pkill -f cord-test
+```
