I have created a task in my org with 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

    This is because as of Spring 2012, the data will not be in the org during testing and must be recreated from your test methods unless you use the IsTest(SeeAllData=true) annotation. From 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 test method with the
    IsTest(SeeAllData=true) annotation. For more information, see
    IsTest(SeeAllData=true) Annotation.
