How to create portal user in test class or testing with a portal user

Some things to note about the portal and test sample below:

• The organization (your Developer Edition environment, for example) in which this is run MUST have the requisite portal licenses
• The respective portal MUST be enabled in the organization before this test can pass.
• The user that creates the portal user MUST have a Role.

@IsTest

private class PortalRunAsTests {

    enum PortalType { CSPLiteUser, PowerPartner, PowerCustomerSuccess, CustomerSuccess }

    

    static testmethod void usertest() {

        User pu = getPortalUser(PortalType.PowerPartner, null, true);

        System.assert([select isPortalEnabled from user 

                        where id =:pu.id].isPortalEnabled,

                      'User was not flagged as portal enabled.');       

        

        System.RunAs(pu) {

            System.assert([select isPortalEnabled from user 

                            where id =:UserInfo.getUserId()].isPortalEnabled, 

                          'User wasnt portal enabled within the runas block. ');

        }

    }

    

    public static User getPortalUser(PortalType portalType, User userWithRole, Boolean doInsert) {

    

        /* Make sure the running user has a role otherwise an exception 

           will be thrown. */

        if(userWithRole == null) {   

            

            if(UserInfo.getUserRoleId() == null) {

                UserRole r = new UserRole(name = 'TEST ROLE');

                Database.insert(r);

                

                userWithRole = new User(alias = 'hasrole', email='userwithrole@roletest1.com', userroleid = r.id,

            } else {

                userWithRole = new User(Id = UserInfo.getUserId(), UserRoleId = UserInfo.getUserRoleId());

            }

            

            System.assert(userWithRole.userRoleId!= null, 

                          'This test requires the target org to have at least one UserRole created. Please create a user role in this organization and try again.');

        }

        Account a;

        Contact c;

        System.runAs(userWithRole) {

            a = new Account(name = 'TEST ACCOUNT');

            Database.insert(a);

            Database.insert(c);

        }

        

        /* Get any profile for the given type.*/

        Profile p = [select id from profile where usertype =:portalType.name()limit 1];   

        

        String testemail = 'puser000@amamama.com';

        User pu = new User(profileId = p.id, username = testemail, email = testemail, 

                           emailencodingkey = 'UTF-8', localesidkey = 'en_US',
