I have created a task in my org with the subject "Email Task"

I have written apex code as

public class  TaskInfoDAOClass

{

   public static List<Task> queryTaskInfo ()

    {

integer count = [SELECT count() FROM Task];

System.debug('Row Count :'+ count);

 List<Task> tasks= [SELECT Task.Id,Task.AccountId,Task.Status,Task.Account.Name FROM Task where Task.Subject='Email Task'];

  return tasks;     

  }

}

I have created one test class to test apex code as

@isTest 

public class TestTaskInfoDAO

{

 public static testMethod void testQueryTaskInfo()

 {

List<Task> tasks = TaskInfoDAOClass.queryTaskInfo();

 System.debug ('this is a debug statement');

for (Task t : tasks)

{

 System.debug ('Status '+ t.Status);

  System.debug ('Account name '+ t.Account.Name);

 }

}

when I run this test I am getting 0 as ROW count. please refer apex.log file

The data is not in the org while you're testing and it needs to be recreated from your test methods unless you use the IsTest(SeeAllData=true) annotation. 

According to the Apex manual:

Starting with Apex code saved using Salesforce API version 24.0 and later, test methods don’t have access by default to pre-existing data in the organization, such as standard objects, custom objects, and custom settings data, and can only access data that they create.

You must create test data for each test. You can disable this restriction by annotating your test class or a test method with the IsTest(SeeAllData=true) annotation. For more information, see IsTest(SeeAllData=true) Annotation.
