From f47542be165ebd69b91945041697181b4df63954 Mon Sep 17 00:00:00 2001 From: aktas Date: Wed, 26 May 2021 10:32:32 +0300 Subject: [PATCH] Feature 10509 manual scaling for native K8s charm This robot test created for this specific package https://osm.etsi.org/gitlab/vnf-onboarding/osm-packages/-/merge_requests/154 Test case steps: 1 - Adds packages 2 - Adds K8s Cluster 3 - Creates NS Service 4 - Gets the scale count 5 - Scale-out the NS 6 - Checks scale count 7 - Scale-in the NS 8 - Check scale count 9 - Removes the NS, K8s cluster and packages This commit includes Juju support Change-Id: Iba7c59a65c9ae2607b23c7104e8178e20b502c60 Signed-off-by: aktas --- README.md | 7 +- docker/Dockerfile | 14 ++ robot-systest/lib/juju_lib.robot | 36 +++++ .../k8s_08-simple_k8s_scaling_data.py | 32 +++++ robot-systest/run_test.sh | 4 +- .../testsuite/k8s_08-simple_k8s_scaling.robot | 126 ++++++++++++++++++ 6 files changed, 217 insertions(+), 2 deletions(-) create mode 100644 robot-systest/lib/juju_lib.robot create mode 100644 robot-systest/resources/k8s_08-simple_k8s_scaling_data.py create mode 100644 robot-systest/testsuite/k8s_08-simple_k8s_scaling.robot diff --git a/README.md b/README.md index 2556456..1d7d5dc 100644 --- a/README.md +++ b/README.md @@ -64,6 +64,9 @@ OS_SDNC= # K8S config file K8S_CREDENTIALS= +# Juju data file +JUJU_DATA= + # The following set of environment variables will be used in host # of the robot framework.
