+## 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.
