This is where you will monitor the automated tests to run before deploying a new version of the voice agent. Might seem complicated but it's very simple: from here you are able in one click to ensure that everything is ok on your conversation design.
If you perform an edition on the script, your tests might need to be edited as well.
To do so, you have 2 solutions:
Edit the existing test from the JSON file (that's for the techy 🤓)
Or you can simply delete the previous version of the test & rewrite it on the Chat page.
