Use Firebase Test Lab phone authentication with Firebase UI

Question

My app uses firebase UI and the only sign-in method is through phone verification. I´m trying the Firebase Test lab but firebase UI does not expose the UI elements to enter the phone number and the verification code during the test. I recorded a script in Android studio and uploaded it but for some reason the test failed.

The only information I found about this topic is here but in that case, an email sign-in was used.

Answer 1

Firebase Test Lab can't do phone number authentication because the devices don't have SIM cards or any sort of cellular service. They only have wifi.

Answer 2

just do a master code on the server side on some phone number, for example: phone number: 055-5478-455 master code: 909090 and let google have these credentials, it will serve them like email+password auth.
