To validate an xApp descriptor, you can utilize either the CLI tool or the REST APIs of xapp onboarder.

Prerequisites

• A working RIC instance. Please refer to "RIC Installation Guide" for details.
• xApp descriptor JSON file
• Schema JSON file

Testing using xapp-onboarder CLI tools

1. Find out the ingress IP for your RIC instance. If you deploy RIC using it/dep deployment script, it should be your host(VM)'s IP.

2. Install xapp-onboarder CLI

   git clone "https://gerrit.o-ran-sc.org/r/it/dev"
   cd dev/xapp_onboarder
   pip3 install ./

3. Set up the environment variables for CLI connection

   export CHART_REPO_URL="http://<INGRESS_IP>:32080/helmrepo"
   
   # It should return True if your CLI tool is properly connected to the RIC instance
   cli health

4. Onboard your xApp.

   # Make sure that you have the xapp descriptor config file and the schema file at your local file system
   cli onboard CONFIG_FILE_PATH SHCEMA_FILE_PATH
