From ebddbcb0f76d5320853b3d342e0db36bbf8c6626 Mon Sep 17 00:00:00 2001 From: Jing Zhang Date: Fri, 7 Apr 2017 21:35:00 -0400 Subject: Extend TC008 to run pktgen-dpdk inside VM Need a fast path inside VM to verify full throughput of SRIOV and OVS-dpdk. Update 1: Change newly added file names to avoid conflict Update 2: Add more unit test cases Update 3: Fix default parameter typo for testpmd Update 4: Adapted to the pktgen-dpdk prompt change from "Pktgen>" to "Pktgen:/>", now just expect "Pktgen" Update 5: Per comment, merge common functions between latency and throughput tests to utils.py Update 6: Per comment, seperate the test case from TC008 to a new test case TC077 Change-Id: I1f7471d4ba77636a3a66c79c2652578321312185 JIRA: YARDSTICK-614 Signed-off-by: Jing Zhang --- .../networking/test_pktgen_dpdk_throughput.py | 186 +++++++++++++++++++++ 1 file changed, 186 insertions(+) create mode 100644 tests/unit/benchmark/scenarios/networking/test_pktgen_dpdk_throughput.py (limited to 'tests/unit/benchmark/scenarios/networking/test_pktgen_dpdk_throughput.py') diff --git a/tests/unit/benchmark/scenarios/networking/test_pktgen_dpdk_throughput.py b/tests/unit/benchmark/scenarios/networking/test_pktgen_dpdk_throughput.py new file mode 100644 index 000000000..0178165f8 --- /dev/null +++ b/tests/unit/benchmark/scenarios/networking/test_pktgen_dpdk_throughput.py @@ -0,0 +1,186 @@ +############################################################################## +# Copyright (c) 2017 Nokia and others. +# +# All rights reserved.
