Batch Apex - How to write the test class?
Can anyone please help writing a test class?
global class LoanOfficerBatch implements Database.Batchable<sObject> { public String query = 'SELECT Loan_Officer_1a__c,Loan_Officer_1a__r.Email, ConvertedOpportunityId, Name, Phone,' + 'Status, Est_Re_Pull_Date__c, Realtor_Name__c ' + ' FROM Lead'; public EmailTemplate templateId = [Select Id,HtmlValue,Subject from EmailTemplate where name = 'LoanOfficerRecord' LIMIT 1]; global Database.QueryLocator start(Database.BatchableContext bc) { query += ' WHERE CreatedDate = THIS_MONTH AND Loan_Officer_1a__c != null'; return Database.getQueryLocator(query); } global void execute(Database.BatchableContext BC, list<Lead> allLeads) { List<String> convertedOppId = new List<String>(); for(Lead l: allLeads){ convertedOppId.add(l.ConvertedOpportunityId); } Map<Id, Opportunity> opptyMap = new Map<Id, Opportunity>(); for(Opportunity o : [SELECT Id,Name,Contact__r.Name,Contact__r.Phone,Starting_Credit_Score__c,Enrolled_On__c,Est_Re_Pull_Date__c,StageName FROM Opportunity WHERE Id IN: convertedOppId]){ opptyMap.put(o.Id, o); } Map<Id,List<Lead>> leadMap = new Map<Id,List<Lead>>(); List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMEssage>(); if(allLeads != null && allLeads.size() > 0){ for(Lead l: allLeads){ if(!leadMap.containsKey(l.Loan_Officer_1a__c)){ leadMap.put(l.Loan_Officer_1a__c, new List<lead>()); } leadMap.get(l.Loan_Officer_1a__c).add(l); } } if(leadMap.keySet().size() > 0){ Map<Id,Contact> officers = new Map<Id,Contact>([SELECT Id,Email,Name FROM Contact WHERE Id IN: leadMap.keySet()]); for(Id i: leadMap.keySet()){ Contact con = officers.get(i); System.debug(con); if(String.isnOtBlank(con.Email)){ Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage(); mail.setToAddresses(new String[]{con.EMail}); mail.setSubject(templateId.Subject); String html = templateId.HtmlValue; html = html.replace('||OfficerName||',con.Name); String leadsTable = '<table cellpadding="3" cellspacing="3" width="100%" align="center" border="1" style="border-collapse:collapse;">'+ '<tr style="font-weight:bold;"><td>Name</td><td>Phone</td><td>Status</td><td>Est.

2. Test.startTest()
3. Invoke the batch class.
4. Test.stopTest()
You're done. Just keep in mind that there should be exactly 1 batch to execute. If your batch class creates more than 1 batch, it would throw an error in test class.
For e.g.
Test.startTest();
MyBatchClass obj = new MyBatchClass();
Database.executeBatch(obj);
Test.stopTest();
Just create the test data before these and ensure there would only be 1 batch created to be passed to execute() from start().
I have create this one but the code coverage is only 12% can you please help.There is only 1 batch
Convert a few leads before executing your batch. You can convert using apex, link below -
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_dml_convertLead.htm
Just copy the code from the link and tweak it. Convert the lead ls that you are already creating and you may be done with it.
I have copy and paste this but nothing could happen.
use this
code coverage is only 12%
