## CI integration
The automation scripts are available on ILIADE.
The end-to-end test is integrated in the CI flow in a semi-automated manner, comprising 3 steps:
- update a YAML file comprising the IT resources definition, branch and commit number the test has to run on
- run the python script that generates the test from the YAML file
```
python3 obj_build_from_yaml.py py_params_template.yaml fr1.sh
```
- run the test (fr1.sh)
At the date of writing, the test comprises the deployment of the components (epc, eNB, gNB, cots ue) and the execution of 2 pings procedures (20 pings in 20sec, then 5 pings in 1sec)
This automation is run for every integration branch to be merged into develop.
