Hello Developers,

I'm trying to set up our company social sign in with facebook and google, one of the steps is to update the autocreated handler for facebook, I need help with writing a test class for this handler and would appreciate any help. Here is the facebook handler I'm trying to write a test class for:

​​​​​​/** FaceBook Registration Handler example **/ global class SimpleFacebookRegistrationHandler implements Auth.RegistrationHandler{ private static final String ORG_SUFFIX = '.sso.badge.org'; private static final String DEFAULT_ACCOUNTNAME = 'Customers'; private static final String EXTERNAL_USER_PROFILE = 'Customers'; private static final String INTERNAL_USER_PROFILE = 'Standard User'; /** * Let anyone register as long as the required fields are supplied * * We require email, lastName, firstName * * @data - the user's info from the Auth Provider **/ global boolean canCreateUser(Auth.UserData data) { System.debug('canCreateUser was called for ' + (data != null ? data.email : 'null')); Boolean retVal = (data != null && data.email != null && data.lastName != null && data.firstName != null); System.debug('data.username='+data.username); System.debug('data.email='+data.email); System.debug('data.lastName='+data.lastName); System.debug('data.firstName='+data.firstName); return retVal; } /** * Create the User - A required method to implement the Handler Interface * * @param portalId - Id of the Community * @param data - Auth Provider user data describing the User to create * * @return User that has been initialized **/ global User createUser(Id portalId, Auth.UserData data){ if(!canCreateUser(data)) { // Returning null signals the auth framework we can't create the user return null; } // Is this a Community Context? if(data.attributeMap.containsKey('sfdc_networkid')) { System.debug('Registering Community user: ' + data.email); Id contactId; // To keep things modular, we're creating the Contact in a separate method contactId = createContact(data); System.debug('Created contact: '+ contactId); // You'd likely use other logic to assign the Profile Profile p = [SELECT Id FROM profile WHERE name=:EXTERNAL_USER_PROFILE]; System.debug('Found profile: '+ p); // Keeping it modular, we initialize the user in another method User u = createUser(data,p); u.contactId = contactId; return u; } else { //This is not a community, so we Assign an internal profile Profile p = [SELECT Id FROM profile WHERE name=:INTERNAL_USER_PROFILE]; System.debug('Found profile: '+ p); // Keeping it modular, we initialize the user in another method User u = createUser(data,p); return u; } } /** * Update the user * @param portalId - Id of the Community * @param data - Auth Provider user data describing the User to create **/ global void updateUser(Id userId, Id portalId, Auth.UserData data){ System.debug('Update User called for: ' + data.email); User u = new User(id=userId); u.email = data.email; u.lastName = data.lastName; u.firstName = data.firstName; update(u); } /** * Create a Contact * * @param data - Facebook provided context for the User **/ private Id createContact(Auth.UserData data){ Contact contact = new Contact(); contact.LastName = data.lastName; contact.FirstName = data.firstName; contact.Email = data.email; // set Account Id if (data.attributemap.get('accountId') != null){ contact.accountId = data.attributemap.get('accountId'); } else { List<Account> accounts = [select Id from Account where Name =:DEFAULT_ACCOUNTNAME]; System.debug('Found account: ' + accounts); contact.accountId = accounts[0].Id; } insert contact; System.debug('Contact created for ' + data.email + ' id=' + contact.id); return contact.id; } /** * Create and initialize the User but don't save it yet * * @param data - the provided User context from FaceBook * @param p - the Profile we are going to assign to this user * * @return User that has been initialized but not Saved **/ private User createUser(Auth.UserData data, Profile p) { User u = new User(); u.username = data.email + ORG_SUFFIX; u.email = data.email; u.lastName = data.lastName; u.firstName = data.firstName; String alias = data.firstName + data.lastName; //Alias must be 8 characters or less if(alias.length() > 8) { alias = alias.substring(0, 8); } u.alias = alias; u.languagelocalekey = UserInfo.getLocale(); u.localesidkey = UserInfo.getLocale(); u.emailEncodingKey = 'UTF-8'; u.timeZoneSidKey = 'America/Los_Angeles'; u.profileId = p.Id; return u; } }
