Hi All ,

can somebody help me on this please !?
I need to test the below piece of code where i have written this in catch block of some pqr class method
But i am strucked how to test it in anonymous window:
catch (exception ex)
mainclass.mainwrapper wrapp = new mainclass.mainwrapper();
                wrapp.excp= ex;
                wrapp.orgId = UserInfo.getOrganizationId();
                wrapp.winName = UserInfo.getOrganizationName();
                wrapp.cName = 'xyz class';
                wrapp.mName = 'abc method';
                ExceptionLog__c newExceptionLog = new ExceptionLog__c();
                newExceptionLog = mainclass.mno-method(wrapp);
                insert newExceptionLog;


Thanks in Advance !

Account_Asset_Role__c field is unique, we have integer count, while bulk updation if duplicate value is found on Account_Asset_Role__c field, feild will be updated as (duplicate + count) duplicate 1, duplicate 2..... when the new batch starts count again comes to 1
integer count should always maintain its value eg: if count is 2 in first batch than in second batch it should start with 3
please give a solution on this
