+Introduction
+============
+
+This document describes how to install and configure the Data Plane
Development Kit Test Suite (DTS) in a Linux environment.
+DTS is an automation test tool for DPDK, wrote in `Python3`.
+DTS includes one set of test cases and DPDK generic test framework.
+DTS provides test example, references and framework for open source community.
+Based on DTS, everyone can develop their test plan, automation script and
configuration for own features and platform.
+In addition, DTS provides a solution to allow that DPDK developers contribute
their function test to certify their patch integration.
+It only requires limited effort to maintain test cases once merged into DPDK
Test Suite.
+Everyone can utilize DTS to measure performance and functionality for features.
+
+As a generic test framework, DTS provides the following functions:
+
+* Communicate/manage DUT and Tester by SSH connection.
+* Able to work with DUT (Device Under Test), which installed Fedora, Ubuntu,
CentOS, RHEL, etc.
+* Support virtualization hypervisor Qemu.
+* Support both software and hardware traffic generators, including Scapy, TRex
and IXIA®.
+* Provide configure files to customize test suite and test cases to run under
DUT.
+* Provide debug and log functionalities for tracking test cases execution
process.
+* Support to output test result by excel, json, log text file, etc.
+
+DTS environment includes DUT (Device under Test), Tester and Traffic
generator. DPDK are deployed on DUT and DTS can run on the Tester or DUT or the
third machine.
+
+.. note::
+
+ * If run with functional testing, DTS uses `Scapy` as traffic generator,
recommend installing DTS on Tester.
+ * If run with performance testing, DTS can use `TRex` or IXIA as traffic
gengerator based on your deployment and configuration, recommend installing DTS
on DUT.
+ * If use `TRex`, recommend deploying `TRex` and DUT on the same machine
with different sockets.
+
+Please see a functional deployment example in the following figure:
+
+.. figure:: image/dts_func_deploy.png
+
+This architecture provides automatically mechanism to manage tester, DUT and
packet generators, and remove dependency between test script and test
environment/hardware.
+It defines one abstraction layer for DPDK Test Suite, and provides
extensibility to add more test script.
+In the DPDK Test Suite Test Framework, it provides the following modules to
help to manage device, platform, configure and test results.
+
+.. table::

+
+These test script provides example and reference. Everyone can develop their
test cases, verify their features functionality, and commit generic test report
to maintainer.
+, user-defined test cases, test plans and scripts must follow DPDK Test Suite
standard including code standard, naming conventions, configure format, rst
test plan, API.
+
+Please see test cases, which are included in the DPDK compliance test suites:
