Running the tests

From the host machine

If you have installed all the dependecnies, the way of executing the tests is via the following command:

source envfile.rc
robot -d reports -i <testing_tags> testsuite/

From docker container

It is possible to run the tests directly from the repository or using a docker container with the tests.

Create the docker container:

docker build -f docker/Dockerfile -t osmtests .

Options:

--env-file: It is the environmental file where is described the OSM target and VIM
-o <osmclient_version> [OPTIONAL]: It is used to specify a particular osmclient version. Default: latest
-p <package_branch> [OPTIONAL]: OSM packages repository branch. Default: master
-t <testing_tags> [OPTIONAL]: Robot tests tags. [sanity, regression, particular_test]. Default: sanity

Volumes:

<path_to_reports> [OPTIONAL]: It is the absolute path to reports location in the host
<path_to_clouds.yaml> [OPTIONAL]: It is the absolute path to the clouds.yaml file in the host
<path_to_sdncs.yaml> [OPTIONAL]: It is the absolute path to the sdncs.yaml file in the host
<path_to_kubeconfig> [OPTIONAL]: It is the kubeconfig file to be used for k8s clusters

Then, run the tests:

docker run --rm=true -t osmtests --env-file <env_file> \
       -v <path_to_reports>:/reports osmtests \
       -v <path_to_clouds.yaml>:/robot-systest/clouds.yaml \
       -v <path_to_sdncs.yaml>:/robot-systest/sdncs.yaml \
       -v <path_to_kubeconfig>:/root/.kube/config \
       -o <osmclient_version> \
       -p <package_branch> \
       -t <testing_tags>

From an environment identical to OSM CICD

git clone https://osm.etsi.org/gerrit/osm/devops
git clone https://osm.etsi.org/gerrit/osm/IM
git clone https://osm.etsi.org/gerrit/osm/osmclient
git clone https://osm.etsi.org/gerrit/osm/tests
# run HTTP server to server artifacts
devops/tools/local-build.sh --install-qhttpd
# generate debian packages locally that will be served by the HTTP server
devops/tools/local-build.sh --module IM,osmclient,tests stage-2
# create docker image and store it locally as opensourcemano/tests:devel
devops/tools/local-build.sh --module tests

Then, run the tests:

docker run --rm=true -t osmtests --env-file <env_file> \
       -v <path_to_reports>:/reports osmtests \
       -v <path_to_clouds.yaml>:/robot-systest/clouds.yaml \
       -v <path_to_sdncs.yaml>:/robot-systest/sdncs.yaml \
       -v <path_to_kubeconfig>:/root/.kube/config \
       -o <osmclient_version> \
       -p <package_branch> \
       -t <testing_tags>

Test tags

All tests in the testsuites have tags. Tags allow to run only a set of tests identified by a tag. Several tags can be specified when running robot in the following way:

robot -i <tag_01> -i <tag_02> testsuite/

The following tags exist for each testsuite:

A tag per testsuite using its mnemonic (e.g. basic_01)
Cluster tag for each of the statistically similar tests:
- cluster_main: basic_01, basic_05, basic_08, basic_09, basic_15, basic_16, basic_17, hackfest_basic, hackfest_multivdu, hackfest_cloudinit, quotas_01
- cluster_ee_config: basic_06, basic_07, basic_11, basic_12, basic_13, basic_14, k8s_05, k8s_06
- cluster_relations: basic_11, basic_13, basic_14
- cluster_epa: epa_01, epa_02, epa_03, epa_04, epa_05
- cluster_k8s: k8s_01, k8s_02, k8s_03, k8s_04, k8s_05, k8s06, k8s_07, k8s_08, k8s_09, k8s_10, k8s_11, sa_08
- cluster_k8s_charms: k8s_05, k8s_06
- cluster_sa: sa_01, sa_02, sa_07
- cluster_slices: slice_01, slice_02
- cluster_heal: heal_01, heal_02, heal_03, heal_04
- cluster_sol003: sol003_01
daily: for all testsuites that will run in the daily job
regression: for all testsuites that should pass in the current stable branch
sanity: for all testsuites that should be passed by each commit in the stage3 to be successfully verified by Jenkins, currently basic_07, basic_11, k8s_03, k8s_04, sa_02, hackfest_basic, hackfest_cloudinit

In addition, the tag "cleanup" exists in those tests that perform any deletion. In that way, it can be invoked to retry the deletion if the tests were forcefully stopped.

For helping in the migration tests and other scenarios in which you don't want to destroy the deployments immediately, the following tags are used:
- prepare: for the tests that are used to deploy the network services under test
- verify: for the tests that perform the actual testing, or changes for additional verifications (e.g. scaling).
- cleanup: already described above.
So, for instance, you could first deploy a number of network services executing the tests with "prepare" tag, migrate to another OSM version, and then check the behavior executing with the "verify" tag. Finally, use the "cleanup" tag.

Post-processing Robot output files

The output files of Robot include tyipically three files:

report.html: overview of the test execution results in HTML format
log.html: details about the executed test cases in HTML format
output.xml: all the test execution results in machine readable XML format

More information about these files here.

It is possible to use the tool rebot, included as part of the Robot Framework, to post-process the output file output.xml.

# To re-generate log and report from output.xml:
rebot [-d <output_folder>] output.xml

# To re-generate log and report (and optionally new output.xml) to include only certain tags:
rebot [-d <output_folder>] -i <tag1> -i <tag2> ... -i <tagN> [-o <new_output_xml>] output.xml

# To re-generate log and report (and optionally new output.xml) excluding certain tags:
rebot [-d <output_folder>] -e <tag1> -e <tag2> ... -e <tagN> [-o <new_output_xml>] output.xml

# To merge several test executions:
rebot [-d <output_folder>] --merge output1.xml output2.xml ... outputN.xml
