public class AccountSchedula implements Schedulable {
    public void execute(SchedulableContext sc) {
        System.debug(‘ceshi schedula‘);
      
    }
}

测试：@isTest
public class TestAccountSchedule {
static testMethod void myUnitTest() {
        String executeTime = ‘0 0 16 * * ?‘;
        AccountSchedula goodsSchedule = new AccountSchedula();
        System.schedule(‘batch goods‘,executeTime,goodsSchedule);
    }
}

直接run test 便可以看到Log 上的debug信息

global class dldcApprovalofTimecardScheduled implements Schedulable {
    global static void execute(SchedulableContext sc) {
        dldc_Timecard_Approval_Reminder.Approval();
    }
}



global class dldc_Timecard_Approval_Reminder{


    global static void Approval() {
    }
}
