Answer 1

You can follow the detailed tutorial here. The key points to note are

• The user that creates the portal user MUST have a Role.
• getPortalUser() returns a reference to portal user
• You then use this reference with runAs() to check whether Portal permissions are enabled or not

`

@IsTest 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='[email protected]', userroleid = r.id,
                                    emailencodingkey='UTF-8', lastname='Testing', languagelocalekey='en_US',
                                    localesidkey='en_US', profileid = UserInfo.getProfileId(),
                                    timezonesidkey='America/Los_Angeles', 36
            } 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);
            c = new Contact(AccountId = a.id, lastname = 'lastname');
            Database.insert(c);
        }
        /* Get any profile for the given type.*/
        Profile p = [select id
                      from profile
                     where usertype = :portalType.name()
                     limit 1];  
        String testemail = '[email protected]';
        User pu = new User(profileId = p.id, username = testemail, email = testemail,
                           emailencodingkey = 'UTF-8', localesidkey = 'en_US',
                           languagelocalekey = 'en_US', timezonesidkey = 'America/Los_Angeles',
                           alias='cspu', lastname='lastname', contactId = c.id);
        if(doInsert) {
            Database.insert(pu);
        }
        return pu;
    }
}

Use following codes

Set<String> customerUserTypes = new Set<String> {'CSPLiteUser', 'PowerPartner', 'PowerCustomerSuccess',   'CustomerSuccess'};
        Account acc1 = new Account (
        Name = 'newAcc1'
        );  
        insert acc1;
        Contact conCase = new Contact (
        AccountId = acc1.id,
        LastName = 'portalTestUserv1'
        );
        insert conCase;
        //Create user

        Profile prfile = [select Id,name from Profile where UserType in :customerUserTypes limit 1];

        User newUser1 = new User(
        profileId = prfile.id,
        username = '[email protected]',
        email = '[email protected]',
        emailencodingkey = 'UTF-8',
        localesidkey = 'en_US',
        languagelocalekey = 'en_US',
        timezonesidkey = 'America/Los_Angeles',
        alias='nuser',
        lastname='lastname',
        contactId = conCase.id
        );
        insert newUser1;
