Is there a way to automate face ID or Touch ID using xcuitest framework in simulator. Manually I can perform enrolling face/touch id and perform matching or non-matching scenarios. However I would like to know if it can be automated?

Given this post by Kane Cheshire it is possible to automate touch ID and face ID for unit testing by sending a Darwin notification like so :

+ (void)enrolled {
  int token;
  notify_register_check("com.apple.BiometricKit.enrollmentChanged", &token);
  notify_set_state(token, 1);
  notify_post("com.apple.BiometricKit.enrollmentChanged");
}

Only in Objective-C though, so you may need to use a bridging header.

Import the files Biometrics.m and Biometrics.h from his demo on Gitub and you will be able to call Biometrics.enrolled() from your XCTestCase.

    According to https://github.com/facebook/WebDriverAgent/issues/26, it should be possible to simulate a match with `notify_post("com.apple.BiometricKit_Sim.fingerTouch.match")` and a non-match with `notify_post("com.apple.BiometricKit_Sim.fingerTouch.nomatch")`. – Mats Dec 04 '18 at 14:17

    Yes, that is used in the lib I linked ;) – Axel Guilmin Dec 04 '18 at 14:20
  • Wow. Thanks a lot Axel for direction. This post looks really impressive. – sjgmamer Dec 04 '18 at 14:26

Alternatively, if the Touch/FaceId is blocking your XCUITesting, I suggest, you put a simple check like the below to disable the Touch/faceId

guard CommandLine.isRunningUITests else {
    return true
}

extension CommandLine {
    static var isRunningUITests:Bool {
        return CommandLine.arguments.contains("--uitesting")
    }
}

You can easily pass LaunchArguments like below

XCUIApplication().launchArguments.append("--uitesting")
