P4 Pipeline Tests (PTF)
=======================

`PTF <https://github.com/p4lang/PTF>`_ is a Python based data plane test framework.
It is based on unittest, which is included in the standard Python distribution.

To test the P4 pipeline, we are using the following components:

* PTF framework and tests

  * Installs table entries to the device.
  * Generate and verify the traffic.

* Stratum: the software that process P4Runtime requests from PTF and configures the device.
* The device under tests: can be software device like Tofino Model, or a hardware device.
* TRex server: for the line rate test.
