Overview
========

This is the **F**\ast **D**\ata **I**/**O** Project (**FD.io**) **C**\ontinuous
**S**\ystem **I**\ntegration and **T**\esting (**CSIT**) project report for
|csit-release| system testing of |vpp-release|.

This is the full html version, there is also a reduced
`PDF version of this report`_.

The report describes CSIT functional and performance tests and their
continuous execution delivered in |csit-release|. A high-level overview is
provided for each CSIT test environment running in :abbr:`LF (Linux Foundation)`
FD.io Continuous Performance Labs. This is followed by summary of all executed
tests against the |vpp-release| and associated FD.io projects and sub-systems
(Honeycomb, DPDK, NSH_SFC), |csit-release| release notes, result highlights and
known issues discovered in CSIT. More detailed description of each environment,
pointers to CSIT test code documentation and detailed test resuls with links to
the source data files are also provided.
