Test Class Failing : DML Exception

Question

I'm having trouble getting my test class to pass tests. Getting:

System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Select from Add Placeholder Dropdown.: []

Class.TestDocManDocumentTriggerHandler.emptyPlaceHolderInsertLoan: line 24, column 1

@isTest
    public static void emptyPlaceHolderInsertLoan() {
        User usr = createUser();
        LLC_BI__DocManager__c docManager = new LLC_BI__DocManager__c(name='llc_bi_Loan__c');
        insert docmanager;

        LLC_BI__ClosingChecklist__c checklist = new LLC_BI__ClosingChecklist__c(
                    Name = 'DocCheckList',
                    LLC_BI__DocManager__c =  docmanager.id );
        insert checklist;

        LLC_BI__Loan__c loan = BatchTestUtility.addLoan(false,null);
        LLC_BI__LLC_LoanDocument__c doc = new LLC_BI__LLC_LoanDocument__c(
            Name=BatchTestUtility.loanDocman.dClass.Name,
            LLC_BI__DocType__c = BatchTestUtility.loanDocman.dType.Id,
            LLC_BI__Loan__c=loan.Id);
        system.debug('lll '+loan);
        system.debug('doccc'+doc+docmanager+checklist);

        Test.startTest();
        System.runAs(usr) {
            insert doc; //getting error here
        }
        Test.stopTest();

        doc = BatchTestUtility.refresh(doc);
        assertDocumentFields(doc);
    }

                checklist);
        }
    }

    private static sObject assignAndSave(List<sObject> existing, sObject newObject) {
        if (existing.size()>0) {
            return existing.get(0);
        }
        insert newObject;
        return newObject;
    }

My Main Class

Class is failing because if(ccl.size()>0){-- } and it is going to else part{objList[0].adderror('select from addPlacer dropdown')}

Custom Validation Exception simply means that there is a validation rule or a trigger add error in your Salesforce instance that's fired when you are creating your test data .

Look for the rule or add error for with the error message "Select from Add Placeholder Dropdown" in your trigger

Understand the rule and create your test data accordingly so that the code reaches the part of the code that throws the error and then use try and catch in test class where you insert the record .

The exception message needs to be asserted .
