Hello HERVE ABAT,
Officially, I will direct you to your Account Manager, who can get you in touch with our Global Services organization.
Less officially, I would be curious to find out if other organizations have had any combination with that combination of tools.
After doing a little more digging, I found out that there is an open request for explicit support of Selenium with Integrity. Please contact PTC Integrity Lifecycle Management Support mentioning this thread, and have your organization added to this request.
