i am not able to see my code coverage

I have two classes and i am quite puzzle to write their test class and not getting any coverage for them

first Apex Class

global class WS_ZipUtil {

  /**

   * Receive Attachments info from Attachment ParentId

   */

  webService static String getAttachmentById( String sfdcId ){

    if( String.isEmpty( sfdcId ) ) return WS_Util.errorJson('Parameter sfdcId is required.');

    

    List<Attachment> attachmentList =  [SELECT Id, Name, Body, ContentType FROM Attachment WHERE Id = :sfdcId];

    if( attachmentList == null || attachmentList.size() == 0 ) return WS_Util.errorJson('Attachment not found.');

    return wrapAttachmentList( attachmentList );

  }

  //Format JSON String from AttachmentList

  private static String wrapAttachmentList( List<Attachment> attachmentList ){

    List<Object> dataList = new List<Object>();

    for( Attachment at : attachmentList ){

      Map<String, String> atMap = new Map<String, String>();

      //atMap.put( 'Id', at.Id );

      atMap.put( 'Name', at.Name );

      atMap.put( 'Body', EncodingUtil.base64Encode( at.Body ) );

      //atMap.put( 'ContentType', at.ContentType );

      dataList.add( atMap );

    }

    return WS_Util.normalJson( dataList );

  }

}

Second Apex Class

public class WS_Util {

  //Normal Status Code

  private static String API_STATUS_NORMAL = '200';

  //Error Status Code

  private static String API_STATUS_ERROR  = '400';

  /**

   * Normal JSON Response

   */

  public static String normalJson( Object respData ) {

    Map<String, Object> response = new Map<String, Object>();

    response.put('status', API_STATUS_NORMAL);

    if( respData != null ) response.put('data', respData);

    return JSON.serialize( response );

  }

  /**

   * Error JSON Response

   */

  public static String errorJson( String message ) {

    Map<String, Object> response = new Map<String, Object>();

    response.put('status', API_STATUS_ERROR);

    if( message != null ) response.put('error', message);

    return JSON.serialize( response );

  }

}

    Hi Nishant,

    Use the below test class you will get the 100% for both the Classes:

    @istest

    public class WS_ZipUtil_Test {

        static testmethod void TestAttachmentById()

        {

            Account a = new Account(Name='newAcct');

            Test.startTest();

            insert a;

           

            Attachment attach=new Attachment();

            attach.Name='Unit Test Attachment';

            Blob bodyBlob=Blob.valueOf('Unit Test Attachment Body');

            attach.body=bodyBlob;

            attach.parentId=a.Id;

            attach.ContentType = 'application/msword';

            attach.IsPrivate = false;

            attach.Description = 'Test';

            insert attach;

            

            String resp = WS_ZipUtil.getAttachmentById(attach.Id);

        }

        

        static testmethod void TestAttachmentByNullId()

        {

            Id sfdcId;

            String resp = WS_ZipUtil.getAttachmentById(sfdcId);

        }

    }

    Thanks,

    Maharajan.C
