-Overview
-========
-
-.. note::
-
- This section includes an abbreviated version of the VPP Test Framework
- overview maintained within the VPP project. Complete overview can be found
- in `VPP test framework documentation`_.
-
-VPP Unit Test Framework
------------------------
-
-VPP Test Framework is used to ease writing, running and debugging unit tests
-for the VPP. It is based on python as a high level language to allow rapid
-test development. scapy\_ is used as a tool for creating and dissecting
-packets.
-
-VPP Test Framework does not send any packets to VPP directly. Traffic is
-instead injected using VPP packet-generator interfaces. Packets are written
-into a temporary .pcap file, which is then read by the VPP code with packets
-getting injected into the VPP processing nodes.
-
-Similarly, VPP does not send any packets to VPP Test Framework directly.
-Instead, VPP packet capture feature is used to capture and write packets to a
-temporary .pcap file, which is then read and analyzed by the VPP Test
-Framework.
-
-For complete description of the VPP Test Framework including anatomy of a test
-case and detailed documentation of existing VPP unit test cases please refer
-to the `VPP test framework documentation`_
