Subject: [spp] [PATCH 3/3] test: add test for spp_primary
Date: Tue, 17 Dec 2019 11:37:30 +0900
Message-ID: <20191217023730.30477-4-yasufum.o@gmail.com> (raw)
In-Reply-To: <20191217023730.30477-1-yasufum.o@gmail.com>

From: Yasufumi Ogawa <yasufum.o@gmail.com>

This patch is to add a unit test code for spp_primary. Test cases are
defined by following SPP REST API as similar to spp_nfv.

Unit tests are expected to be run in the `test` dir. Specify the name
of test if you run tests for a process, or all processes without the
name.

  $ cd /path/to/spp/test
  $ python3 -m unittest test_spp_primary  # test only spp_primary
  # or
  $ python3 -m unittest  # test all
