Aqua Matrix i want to write a test class for below apex batch class
hii,
i want to write a test class for below apex batch class which covers 75% code coverage.

Please find the below test class which is covering 52%. We are not able to cover more because the apex class is failing with null pointer exception. Null checks were not made properly.
For example : In case of map null check you should use
if(!emailDomainMap.isEmpty() && emailDomainMap!=null){For field null check please use the below.@isTest(SeeAllData=true) public class TestBatchValidate { @istest public static void testmet(){ List<Contact> clist = new List<Contact>(); contact c = new contact(LastName='sample name', FirstName='sample' ,Accountid='0015g00000OYhCxAAL'); clist.add(c); contact c1 = new contact(LastName='sample' ,MatchingEmail1__c='sample@gah.com',FirstName='sample',Accountid='0015g00000OYhCxAAL'); clist.add(c1);a //contact c2 = new contact(LastName='sample',Accountid='0015g00000OYhCxAAL'); // clist.add(c2); contact c3 = new contact(LastName='sample' ,FirstName='sample',email='sample5@gmail.com',Accountid='0015g00000OYhCxAAL'); clist.add(c3); contact c4 = new contact(LastName='sample',FirstName='sample',email='sample6@gmail.com' ,Accountid='0015g00000OYhCxAAL'); clist.add(c4); contact c5 = new contact(LastName='sample' ,FirstName='sample',email='sample7@gmail.com',Accountid='0015g00000OYhCxAAL'); clist.add(c5); insert(clist); Test.startTest(); BatchUpdateContactEmail obj = new BatchUpdateContactEmail(); DataBase.executeBatch(obj); Test.stopTest(); } @istest public static void testmet2(){ List<Contact> clist = new List<Contact>(); contact c = new contact(LastName='sample name',FirstName='sample',email='sample@gdsdmail.com' ,Accountid='0015g00000OYhCxAAL'); clist.add(c); insert(clist); Test.startTest(); BatchUpdateContactEmail obj = new BatchUpdateContactEmail(); DataBase.executeBatch(obj); Test.stopTest(); } }If this solution helps, Please mark it as best answer.
Thanks,
Iam getting following error please help me solve this error:
Can you please check if the class name is unique. You will get this error if there is another class with same name.
Thanks,
