[SalesForce] Apex Test class (Field is not writeable: CampaignMember.RecordTypeId)

I really am not sure what I am doing wrong here but I am being thrown the error I am doing exactly what I have read to do on stackoverflow and in the SF docs. Any ideas?:

Field is not writeable: CampaignMember.RecordTypeId (Line: 7, Column: 11)

@isTest
private class TestCampaignMemberTrigger {
    @isTest
    static void test_method_one() {
        CampaignMember cmPhone = new CampaignMember();
        Id phone = Schema.SObjectType.CampaignMember.getRecordTypeInfosByName().get('Fundraising_Dinners').getRecordTypeId();
        cmPhone.RecordTypeId=phone;
    }   
}

Documentation about RecordTypeId field on CampaignMember says:

ID of the record type assigned to this object. To change the record type, modify the CampaignMemberRecordTypeId field on the associated Campaign.

so you can't assign record type to CampaignMember record in this way. Select related Campaign and change CampaignMemberRecordTypeId field

You cannot create or update the value for formula fields. The only way to control their value is to set up the related data in a way that it calculates what you want. In this case, you would need to set the parent Relationship__c and then insert the record:

mem.Relationship__c = rc.Id;
insert mem;

CAM_Members insertedRecord = [
    SELECT Affiliate_State__c FROM CAM_Members__c WHERE Id = :mem.Id
];
system.assertEquals(a1.BillingState, insertedRecord.Affiliate_State__c, '<message_here>');

That said, you shouldn't test the output of your formulas with a unit test. You should use regression testing to verify their behavior. Unit tests on configuration aspects which can be easily changed are very brittle and will harm your org health in the long run.
