How to automate bio-metric identification like face recognition and fingerprint?

Question

So I'm trying to automate an application end to end and it involves facial recognition to store the photo of user. The user can use the front camera/rear camera and within a few seconds it detects the facial features and store it. Is there any tool which can be used to verify this functionality or should I just use a stub to verify the integration?
