Apex Class test failure: System.ListException: List index out of bounds: 0

Question

I've had this code working in my account for a year now. When I run a test in the Developer console, no errors are generated. But when I package it up for distribution I get an error: System.ListException: List index out of bounds: 0 Class.TTCreateCampaignMemberStatus.CampaignInsert: line 6, column 1

From what I've read it seems I need to account for the situation that the list returns zero values. Would love some advice on how to fix this. Here is the code:

@isTest
private class TTCreateCampaignMemberStatus
{
    static testMethod void CampaignInsert() {
        List<RecordType> rt = [select Id, name from RecordType where SobjectType = 'Campaign' and name = 'Events and Meetings'];
        Campaign testCampaign = new Campaign(Name='Test Test Campaign',RecordTypeId=rt[0].Id);
        insert testCampaign;
        Integer i =[Select count() FROM CampaignMemberStatus WHERE CampaignID=:testCampaign.id];
        System.assertEquals(5,i);
    }
}

Answer 1

When you run this code in your original environment, it's finding the RecordType that you had manually created in that org. You'd get the same result both running the test and running the code in the console.

Packaging and deploying to a fresh organization without that RecordType fails if it hasn't been included in the package or manually created beforehand.

The immediate fix is to include the RecordType in your package, and then refine your test as Mike and James have suggested.

This is a Salesforce Bug.

Use this code in your test method in place of the query:

@isTest
private class TTCreateCampaignMemberStatus{
    static testMethod void CampaignInsert() {
        //List<RecordType> rt = [select Id, name from RecordType where SobjectType = 'Campaign' and name = 'Events and Meetings'];
        Schema.DescribeSObjectResult cfrSchema = Schema.SObjectType.Campaign; 
        Map<String,Schema.RecordTypeInfo> CampaignRecordTypeInfo = cfrSchema.getRecordTypeInfosByName(); 
        Id rtId = CampaignRecordTypeInfo.get('Events and Meetings').getRecordTypeId();

        //Campaign testCampaign = new Campaign(Name='Test Test Campaign',RecordTypeId=rt[0].Id);
        Campaign testCampaign = new Campaign(Name='Test Test Campaign',RecordTypeId=rtId);
        insert testCampaign;
        Integer i =[Select count() FROM CampaignMemberStatus WHERE CampaignID=:testCampaign.id];
        System.assertEquals(5,i);
    }
}
