 TestON is the testing platform that all the ONOS tests are being run on currently. 
 
 
-Setup 
+Code Style
+-------------
+At ON.Lab, we have adopted the [Mininet Python style](https://github.com/mininet/mininet/wiki/Mininet-Python-Style) for our drivers and testcases. The one exception is that TestON does not correctly parse multiline comments in testcases when the ending triple double quotes are on the same line as the comment. Therefore, in the testcases, the ending triple double quotes must be on it's own line.

-Mininet Installation/Configuration Notes
-----------------------------------------
-
-Mininet 2.0.0
----
-
-The supported installation methods for Mininet are 1) using a
-pre-built VM image, and 2) native installation on Ubuntu. You can also
-easily create your own Mininet VM image (4).
-
-(Other distributions may be supported in the future - if you would
-like to contribute an installation script, we would welcome it!)
-
-1. Easiest "installation" - use our pre-built VM image!
-
-   The easiest way to get Mininet running is to start with one of our
-   pre-built virtual machine images from <http://openflow.org/mininet>
-
-   Boot up the VM image, log in, and follow the instructions on the
-   Mininet web site.
-
-   One advantage of using the VM image is that it doesn't mess with
-   your native OS installation or damage it in any way.
-
-   Although a single Mininet instance can simulate multiple networks
-   with multiple controllers, only one Mininet instance may currently
-   be run at a time, and Mininet requires root access in the machine
-   it's running on.  Therefore, if you have a multiuser system, you
-   may wish to consider running Mininet in a VM.
-
-2. Next-easiest option: use our Ubuntu package!
-
-   To install Mininet itself (i.e. `mn` and the Python API) on Ubuntu
-   12.10+:
-
-        sudo apt-get install mininet
-
-   Note: if you are upgrading from an older version of Mininet, make
-   sure you remove the old OVS from `/usr/local`:
-
-        sudo rm /usr/local/bin/ovs*
-        sudo rm /usr/local/sbin/ovs*
-
-3. Native installation from source on Ubuntu 11.10+
-
-   If you're reading this, you've probably already done so, but the
-   command to download the Mininet source code is:
-
-        git clone git://github.com/mininet/mininet.git
-
-   If you are running Ubuntu, you may be able to use our handy
-   `install.sh` script, which is in `mininet/util`.
-
-   *WARNING: USE AT YOUR OWN RISK!*
-
-   `install.sh` is a bit intrusive and may possibly damage your OS
-   and/or home directory, by creating/modifying several directories
-   such as `mininet`, `openflow`, `oftest`, `pox`, or `noxcosre`.
-   Although we hope it won't do anything completely terrible, you may
-   want to look at the script before you run it, and you should make
-   sure your system and home directory are backed up just in case!
-
-   To install Mininet itself, the OpenFlow reference implementation, and
-   Open vSwitch, you may use:
-
-        mininet/util/install.sh -fnv
-
-   This should be reasonably quick, and the following command should
-   work after the installation:
-
-        sudo mn --test pingall
-
-   To install ALL of the software which we use for OpenFlow tutorials,
-   including POX, the OpenFlow WireShark dissector, the `oftest`
-   framework, and other potentially useful software (and to add some
-   stuff to `/etc/sysctl.conf` which may or may not be useful) you may
-   use:
-
-        mininet/util/install.sh -a
-
-   This takes about 4 minutes on our test system.
-
-4. Creating your own Mininet/OpenFlow tutorial VM
-
-   Creating your own Ubuntu Mininet VM for use with the OpenFlow tutorial
-   is easy! First, create a new Ubuntu VM. Next, run two commands in it:
-
-        wget https://raw.github.com/mininet/mininet/master/util/vm/install-mininet-vm.sh
-        time install-mininet-vm.sh
-
-   Finally, verify that Mininet is installed and working in the VM:
-
-        sudo mn --test pingall
-
-5. Installation on other Linux distributions
-
-   Although we don't support other Linux distributions directly, it
-   should be possible to install and run Mininet with some degree of
-   manual effort.
-
-   In general, you must have:
-
-   * A Linux kernel compiled with network namespace support enabled
-
-   * An OpenFlow implementation (either the reference user or kernel
-     space implementations, or Open vSwitch.) Appropriate kernel
-     modules (e.g. tun and ofdatapath for the reference kernel
-     implementation) must be loaded.
-
-   * Python, `bash`, `ping`, `iperf`, etc.`
-
-   * Root privileges (required for network device access)
-
-   We encourage contribution of patches to the `install.sh` script to
-   support other Linux distributions.
-
-
-Good luck!
