Apex单元测试没有数据

Question

我在我的组织中创建了一个主题为"电子邮件任务"的任务

我写了一个顶点代码

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;     
  }
}

我创建了一个测试类来测试顶点代码

@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);

 }
}
} 

当我运行这个测试时,我得到0作为ROW计数.请参考apex.log文件

为什么我得到0 ROW COUNT？

Answer 1

这是因为从2012年春季开始,测试期间数据不会出现在组织中,必须从测试方法重新创建,除非您使用IsTest(SeeAllData = true)注释.从Apex手册:

从使用Salesforce API 24.0及更高版本保存的Apex代码开始,测试方法默认情况下无权访问组织中预先存在的数据,例如标准对象,自定义对象和自定义设置数据,并且只能访问他们创造.

您必须为每个测试创建测试数据.您可以通过使用IsTest(SeeAllData = true)批注对测试类或测试方法进行批注来禁用此限制.有关更多信息,请参阅IsTest(SeeAllData = true)注释.

Answer 2

您需要在测试方法的开头插入一个主题为"电子邮件任务"的任务.从最新版本开始,测试方法无法访问系统中已有的数据,这可确保测试与orgs之间的覆盖范围更加一致.这也意味着我们不再需要在代码中添加测试特定子句,以确保在查询大型数据集时选择正确的记录!
