Which are the next steps on support biometric library testing?

I have a business logic with a KeyStore RSA key created with the setUserAuthenticated(true) and setUserAuthenticationValidityDurationSeconds(-1) and the use of the resulting authenticated CryptoObject

How can I bypass the BiometricPrompt.authenticate checks for a lock screen and fingerprint enrolled? In the emulator this is returning BiometricPrompt.ERROR_CANCELED even with fingerprint and lock screen added because probably it doesn't find the fingerprint hardware.

In a CI environment with emulators I can't setup lock screen from command line.

I can do this: adb emu finger touch 1 to simulate a finger press but I don't have nothing to set a lock screen with PIN to reach the enrollment step.

Manually I can do this from test application:

val fingerprintEnrollIntent = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    Intent(Settings.ACTION_FINGERPRINT_ENROLL)
} else {
    //we don't have a specific action before P, we need to guide the user with dialogs
    //and call canAuthenticate again to check if he really completed the procedure
    Intent(Settings.ACTION_SECURITY_SETTINGS)
}
startActivityForResult(fingerprintEnrollIntent, REQUESTCODE_FINGERPRINT_ENROLLMENT)

but I don't have nothing to do this with command line and prepare an emulator for biometric instrumentation testing and even if there is a way I probably can't call adb emu finger touch 1 from an instrumentation test to authenticate in an emulator.

So there should be a "software" way to test biometric and not relaying on emulator configuration for this.

Are there solutions to this problem?

Thank you
