Hi All,

I am getting above error in my test class at 16 and 40, below is my code.
Please help.

Apex class:

public class ImportCSV1 {

    public Blob csvFileBody{get;set;}
    public  string csvAsString{get;set;}
    public  String[] csvFileLines{get;set;}
    public List<account> acclist{get;set;}
    public ImportCSV1(){
    csvFileLines = new String[]{};
    acclist = New List<Account>(); 
  }
  
  public  void importCSVFile(){
       try{
           csvAsString = csvFileBody.toString();
           csvFileLines = csvAsString.split('\n'); 
            
           for(Integer i=1;i<csvFileLines.size();i++){
               Account accObj = new Account() ;
               string[] csvRecordData = csvFileLines[i].split(',');
               accObj.name = csvRecordData[0] ;             
               accObj.accountnumber = csvRecordData[1];
               accObj.Phone = csvRecordData[2];
               accObj.Industry = csvRecordData[3]; 
               accObj.Type = csvRecordData[4];
               accObj.Description = csvRecordData[5];
               accObj.Website = csvRecordData[6];
               accObj.Site = csvRecordData[7];
               accObj.Ownership = csvRecordData[8];
               accObj.Sic = csvRecordData[9];
               acclist.add(accObj);   
           }
        insert acclist;
        }
        catch (Exception e)
        {
            ApexPages.Message errorMessage = new ApexPages.Message(ApexPages.severity.ERROR,'An error has occured while importin data Please make sure input csv file is correct');
            ApexPages.addMessage(errorMessage);
