hi all,

  i am writhing the bellow test class to cover the code to my class this class will cover the other trigger in this we are inserting the object
when we inserting the parent object values the cheld trigger is having the other trigger its showing exception please help me on this

/**
*    Class : BondDetail Test class

@isTest
class BondDetailTest{
    static testMethod void TestBondDetail() {
        TestCases_Helper.insertCustomSettingData(Branch__c.sObjectType, 'BranchCodeCustomSettings');

        bondRec.Issue_To_Date__c = Date.today();
        bondRec.Private_Public_Division__c = 'PO';
        insert bondRec;
        
        PageReference pRef = Page.BondDetail;
        pRef.getParameters().put('Id', bondRec.id);
        Test.setCurrentPage(pRef);
        
        Test.startTest();
            BondDetail  BD= new BondDetail();
            System.assertNotEquals(null, BD.BondID, 'Bond ID should be available.');
            System.assertEquals(BD.BondID, bondRec.id, 'ID\'s should match');
            BD.CreateAllocation();
            
            BD.back();
        Test.stopTest();
        
    }

}
in this Branch_Allocation__c is a chield object and  Bond__c is a parent but i am getting error like after insert no records found
