+## Autogeneration of tests
+
+There is a tool `robot-systest/autogeneration/generate_osm_test.py` that allows generating a Robot test from a YAML configuration:
+
+```bash
+$ ./generate_osm_test.py -h
+usage: generate_osm_test.py [-h] [-v] --config CONFIG [--template TEMPLATE] [--output OUTPUT]
+
+Generate OSM tests from YAML configuration file.
+
+options:
+ -h, --help show this help message and exit
+ -v, --verbose increase output verbosity
+ --config CONFIG yaml configuration file to create the test
+ --template TEMPLATE template file for rendering the test (default: test_template.j2)
+ --output OUTPUT output file (default: standard output)
+```
+
+A YAML configuration file provides the input parameters to generate the test, such as NF and NS packages, NS instances to be created and some operations to be executed once the NS instances are created. An example can be found in `robot-systest/autogeneration/test_config.yaml`:
+
+```yaml
+documentation: "[BASIC-40] Auto-generated test"
+name: basic_40
+tags:
+ - basic_40
+ - cluster_main
+ - daily
+nfpkg:
+ - package: hackfest_basic_vnf
+ name: hackfest_basic-vnf
+ - package: hackfest_basic2_vnf
+ name: hackfest_basic2-vnf
+nspkg:
+ - package: hackfest_basic_ns
+ name: hackfest_basic-ns
+ - package: hackfest_basic2_ns
+ name: hackfest_basic2-ns
+ns:
+ - name: basic_40
+ nspkg: hackfest_basic-ns
+ config: "{vld: [ {name: mgmtnet, vim-network-name: %{VIM_MGMT_NET}} ] }"
+vnf:
+ - ns: basic_40
+ vnf_member_index: vnf
+ tests:
+ - type: ping
+ - type: ssh
+```
+
+To generate the Robot, you can run:
+
+```bash
+cd robot-systest/autogeneration/
+./generate_osm_test.py --config test_config.yaml > ../testsuite/mynewtest.robot
+```
