+           -v ~/osm-packages:/robot-systest/osm-packages \
+           opensourcemano/tests:testing-daily \
+           -t sol003_01
 ```
 
-## Deployment
+Relevant volumes to be mounted are:
+
+- <path_to_reports> [OPTIONAL]: the absolute path to reports location in the host
+- <path_to_clouds.yaml> [OPTIONAL]: the absolute path to the clouds.yaml file in the host
+- <path_to_sdncs.yaml> [OPTIONAL]: the absolute path to the sdncs.yaml file in the host
+- <path_to_kubeconfig> [OPTIONAL]: the kubeconfig file to be used for k8s clusters
+
+Other relevant options to run tests are:
+
+- `--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
 
-It is possible to run the tests directly from the repository or using a docker container with the tests
+## How to run tests from a host
 
-1. Docker container creation:
+In general, testing from docker images is the best way if you want to develop for OSM. However, sometimes it could be useful to run tests directly from the host.
+
+### Install dependencies
+
+This bash script can be used to setup your environment to execute the tests.
 
 ```bash
-docker build -f docker/Dockerfile -t osmtests .
+sudo apt-get update
+sudo apt-get install ssh ping yq git
+# Python packages used for the tests
+python3 -m pip install -r requirements.txt
+python3 -m pip install -r requirements-dev.txt
+# Download community packages
+git clone https://osm.etsi.org/gitlab/vnf-onboarding/osm-packages.git
 ```
 
-Options:
+### Configure the environment
 
-* --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
+Create a file `envconfig.rc` copying from `envconfig-local.rc` and set the required variables (in this case, the use of `export` is mandatory).
 
-Volumes:
+```
+export OSM_HOSTNAME=<OSM_IP_ADDRESS>
+export VIM_TARGET=<VIM_REGISTERED_AT_OSM>
+export VIM_MGMT_NET=<NAME_OF_THE_MGMT_NETWORK_IN_THE_VIM>
+export OS_CLOUD=<OPENSTACK_CLOUD>    # OpenStack Cloud defined in $HOME/.config/openstack/clouds.yaml or in /etc/openstack/clouds.yaml
+export K8S_CREDENTIALS= # path to the kubeconfig file of the K8s cluster to be tested
+export OCI_REGISTRY_URL= # URL of the OCI registry where helm charts used in test packages are stored. 
+export OCI_REGISTRY_USER= # User of the OCI registry
+export OCI_REGISTRY_PASSWORD= # Password of the OCI registry
+```
+
+### Running the tests
+
+```bash
+source envconfig.rc
+mkdir reports
+robot -d reports -i <testing_tags> testsuite/
+```
+
+## How to run tests from an environment identical to OSM CICD
+
+```bash
+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
+```
 
-* <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_kubeconfig> [OPTIONAL]: It is the kubeconfig file to be used for k8s clusters
+Then, run the tests:
 
 ```bash
-   docker run --rm=true -t osmtests --env-file <env_file> \
+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>
 ```
 
-1. Running the tests manually:
+## Test tags
 
-The way of executing the tests is via the following command:
+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:
 
 ```bash
-   source envfile.rc
-   robot -d reports -i <testing_tags> testsuite/
+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`, `k8s_12`, `k8s_13`, `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_osm_rest`: `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 `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](https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#output-file).
+
+It is possible to use the tool `rebot`, included as part of the Robot Framework, to post-process the output file `output.xml`.
+
+```bash
+# 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
+```
+
+More information about post-processing Robot output files [here](https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#post-processing-outputs)
