I have written the following batch apex class and corresponding test class. Tests are successful but the execute method is never called. I have attempted to debug to try to pinpoint the problem but have had no luck.

Batch Class

global class BatchAddToCampaign implements Database.Batchable<sObject>,  Database.Stateful
    global final Id campaignId;
    global final Set<Id> qKeys;

    global BatchAddToCampaign(Id campaignId, Set<Id> qKeys){
        this.campaignId = campaignId;
        this.qKeys = qKeys;
    System.Debug('this.campaignId is ' + campaignId);         
    System.Debug('this.qkeys is ' + qKeys);                 


    global Database.QueryLocator start(Database.BatchableContext BC) {
        return Database.getQueryLocator('Select Id From Lead Where Id In :qKeys');

    global void execute(Database.BatchableContext BC, List<Lead> scope) {
        System.Debug('Starting Execute Method!');         
        Integer collsize; 
        List<CampaignMember> cm = new List<CampaignMember>();   
        Map<Id, Campaign> cmMap = new Map<Id, Campaign>([Select (Select LeadId From CampaignMembers) From Campaign c Where Id = :campaignId]);
         for(Lead myLeads : scope) {
             CampaignMember newCM = new CampaignMember(
             CampaignId = campaignId,
             LeadId = myLeads.Id,
             status = 'Added' );

                 if (!cmMap.containsKey(myLeads.Id)) {
                     collsize = cm.size();

         try {
         } catch (DmlException ex) {
            System.Debug('Insert failed ' + ex);

    global void finish(Database.BatchableContext BC) {
        AsyncApexJob a = [SELECT Id, Status, NumberOfErrors, JobItemsProcessed,  TotalJobItems, CreatedBy.Email From AsyncApexJob Where Id = :BC.getJobId()];
        // Send an email to the Apex job's submitter notifying of job completion.
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        String[] toAddresses = new String[] {a.CreatedBy.Email};
        mail.setSubject('Add to Campaign ' + a.Status);
        String campaignURL = URL.getSalesforceBaseUrl().toExternalForm() + '/' + campaignId;
        mail.setPlainTextBody('The batch Apex job processed ' + a.TotalJobItems + ' batches with '+ a.NumberOfErrors + ' failures. ' + 'Link to Campaign: ' + campaignURL);
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

Test Class

public class BatchAddToCampaignTest
    static testMethod void testMethod1()
        List<Lead> lstCM= new List<Lead>();
        for(Integer i=0 ;i <1;i++){
            Lead myLead = new Lead();
            myLead.Id = '00Q1U00000KqFcDUAV';
            Integer collSize = lstCM.size(); 
            System.debug('List Collection Size is ' + collSize);

                System.debug('Start Set');
                Set<Id> leadIds = (new Map<Id,SObject>(lstCM)).keySet();
                System.debug('End Set');
                Integer collSizeSet = leadIds.size(); 
                System.debug('Set Collection Size is ' + collSizeSet);
                Id workingCampaignId = '7011U000000RWRAQA4';


                //BatchAddToCampaign ba = new BatchAddToCampaign(workingCampaignId, leadIds);
                DataBase.executeBatch(new BatchAddToCampaign(workingCampaignId, leadIds));


  • It won't execute because you don't have any data. You need to update the test to insert some data before you run the batch.

    You also have a for loop running the Test.startTest() and stopTest(). I know it's a for loop that only runs one time, the Test start and stop, as well as the executeBatch should definitely not be running in a loop block context Feb 23, 2020 at 18:34

Your unit tests execute in an isolated data environment and cannot see the records with the hard-coded Salesforce Ids you've included. Hence, your query returns no records.

Your unit tests should always generate their own data within test context. See How do I write an Apex unit test? for links to great resources on how to do this well.
