@PatelRomil -- I have implemented the BiometricPrompt API to authenticate the fingerprint for login in our app and now I wanted to write the espresso test to validate it. Is there any possibility to write the espresso test for the Google provided API(BiometricPrompt). – Sherrylsherurd

I had the same question myself. Guess it's one of those things you can't automate a test. – Bourbonism
