Could you help me in writing the test class for before insert trigger.

trigger PositionTrigger on Position__c (before insert,before update, before delete) {
    if(trigger.isBefore && (trigger.isInsert || trigger.isUpdate)){
        PositionTrigger_Handler.RecordTypeUpdate(Trigger.New);
    }
}
=============
public class PositionTrigger_Handler {
    Public Static void RecordTypeUpdate(List<Position__c> lstpos){
        Map<string,id> MappingRec = new Map<string, id>();
        List<RecordType> lstRec = [Select id, Developername from RecordType where SObjectType = 'Position__c'];
        for(RecordType rec: lstRec){
            MappingRec.put(rec.DeveloperName, rec.Id);
        }
        for(Position__c pos : lstpos){
            if(pos.Phase__c == 'Phase 1'){
                pos.RecordTypeId = MappingRec.get('Phase_1');
            }
            if(pos.Phase__c == 'Phase 2'){
                pos.RecordTypeId = MappingRec.get('Phase_2');
            }
            if(pos.Phase__c == 'Phase 3'){
                pos.RecordTypeId = MappingRec.get('Phase_3');
            }
        }
    }
}
=============================
@isTest
public class PositionTrigger_Handler_Test {
    
    Static testmethod void TestTrigger (){
        List<Position__c> lstpos = New List<Position__c> ();
        try{
            Position__C pos1 = New Position__C(Name='Test1', Amount__c=500, Phase__c='Phase 1');
            Position__C pos2 = New Position__C(Name='Test2', Amount__c=500, Phase__c='Phase 2');
            Position__C pos3 = New Position__C(Name='Test3', Amount__c=500, Phase__c='Phase 3');
            lstpos.add(pos1);
            lstpos.add(pos2);
            lstpos.add(pos3);
            insert lstpos;   
        }
        catch(DmlException e){
            system.debug('the following exception has occured: '+e.getMessage());
        }
        
    }
}

Hi Adil,

You need to compare the recordtype id that is assigned from the trigger and expected value.
It covers 100% trigger and handler apex class as well
  
@isTest
public class PositionTrigger_Handler_Test {
    
    Static testmethod void TestTrigger (){
        List<Position__c> lstpos = New List<Position__c> ();
        try{
            Position__C pos1 = New Position__C(Name='Test1', Phase__c='Phase 1');
            Position__C pos2 = New Position__C(Name='Test2', Phase__c='Phase 2');
            Position__C pos3 = New Position__C(Name='Test3',Phase__c='Phase 3');
            lstpos.add(pos1);
            lstpos.add(pos2);
            lstpos.add(pos3);
            insert lstpos;  
            Map<string,id> MappingRec = new Map<string, id>();
       
            List<RecordType> lstRec = [Select id, Developername from RecordType where SObjectType = 'Position__c'];
        for(RecordType rec: lstRec){
            MappingRec.put(rec.DeveloperName, rec.Id);
        }
           system.assertEquals(pos1.RecordTypeId, MappingRec.get('Phase_1'));
            system.assertEquals(pos2.RecordTypeId, MappingRec.get('Phase_2'));
            system.assertEquals(pos3.RecordTypeId, MappingRec.get('Phase_3'));
        }
        catch(DmlException e){
            system.debug('the following exception has occured: '+e.getMessage());
        }
        
    }
}

hi Adil,
try below test class with 100% coverage 
@isTest
public class PositionTrigger_Handler_Test {
    
    private Static testmethod void createPosition(){
        List<Position__c> lstPosition = New List<Position__c> ();
        
		  for(integer i=1; i<=3; i++){
			Position__C pos = New Position__C(Name='Test ' +i, 
			                                  Phase__c='Phase ' + i);
/* Add all the required fieds by comma seprate*/											  
			  lstPosition.add(pos);
		  }
		  test.startTest();
               if(lstPosition.size() > 0){
			      insert lstPosition;  	   
			   }
		  test.stopTest();
		  
		  
		  
            
        
    }
}
