Making a test plan for account kit
common flows:
1. User logs in with phone number
2. User logs in with email

How can the Graph API make app better?
-increased personalization
-more opportunities for social interaction

Better personalization and more opportunities for social interaction can lead to improvements in:
-Engagement
-Retention

Facebook Graph API
https://developers.facebook.com/docs/graph-api?locale=ja_JP

if (accessToken != null &&
accessToken.getPermissions().contains("user_friends")){
	// make the API call to fetch friends list
	Bundle parameters = new Bundle();
	parameters.putString("fields", "picture");
	new GraphRequest(
	AccessToken.getCurrentAccessToken(), "/me/friends",HttpMethod.GET,...);
}.executeAsync();

Implementing the logout button manually

public void onLogout(View view){
	AccountKit.logOut();
	LoginManager.getInstance().logOut();
	launchLoginActivity();
}

How to Test: Making a Test Plan
unexpected conditions:
1.A new user declines to authenticate permissions once, then tries to log in again
2.A returning user who has changed their password
3.A returning user with an expired token
4.A returning user who logs in after disabling the Facebook platform

Account kit
Common Flows:
1. A user logs in with a phone number
2. A user logs in with an email address

Unexpected conditions:
1. A user tries to log in, but does not receive the SMS
2. A user types in the wrong code
