-Pipeline Tests (PTF)
-====================
+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.
