SQL存储过程测试（9）——示例程序

    此部分内容创建一个轻量级T-SQL测试套件，总共有3个脚本：

 

用于创建测试平台数据和待测存储过程的脚本

 

--======================
--makeDbTestAndResults.sql

use master
go

if exists (select * from sysdatabases where name = 'DbTestAndResults')
 drop database makeDbTestAndResults
go

if exists (select * from sysxlogins where name = 'testLogin')
 exec sp_droplogin 'testLogin'
go

create database makeDbTestAndResults
go

use makeDbTestAndResults
go

create table tb1TestCases
(
 caseID char(4) primary key,
 input datetime not null,
 expectedChecksum int not null
)
go

--下面插入的是用于usp_HiredAfter的测试数据，采用了对期望值求校验和的方法
--也可以通过BCP,BTS或者C#程序从文本文件读入这些数据

insert into tb1TestCases values('0001','10/25/2009',1042032)
insert into tb1TestCases values('0002','10/25/2009',9999999)--deliberate error
insert into tb1TestCases values('0003','10/25/2008',25527856)
insert into tb1TestCases values('0004','10/10/2006',1042032)
go

create table tb1Results
(
 caseID char(4) not null,
 result char(4) not null,
 whenRun datetime not null
)
go

exec sp_addlogin 'testLogin','secret'
go

exec sp_grantdbaccess 'testLogin'
go

grant select,insert,delete,update on tb1TestCases to testLogin
go

grant select,insert,delete,update on tb1Results to testLogin
go

--结束脚本

 

用于创建测试例例数据和测试结果存储的脚本

 

--==========================
--makeDbEmployees.sql
use master
go

if exists(select * from sysdatabases where name = 'dbEmployees')
 drop database dbEmployees
go

if exists(select * from sysxlogins where name = 'employeesLogin')
 exec sp_droplogin 'employeesLogin'
go

create database dbEmployees
go

use dbEmployees
go

create table tb1Employees
(
 empID char(3) primary key,
 empLast varchar(35) not null,
 empDOH datetime not null,
)
go

insert into tb1Employees values('e11','Adams','10/25/2009')
insert into tb1Employees values('e22','Baker','10/25/2009')
go

exec sp_addlogin 'employeesLogin','secret'
go

exec sp_grantdbaccess 'employeesLogin'
go

create procedure usp_HiredAfter
 @dt datetime
as
 select * from tb1Employees where empDOH > @dt
go

grant execute on usp_HiredAfter to employeesLogin
go

--end script

自动化测试套件脚本

 

--=================================
--SQLspTest.sql
--测试dbEmployees..usp_HiredAfter
--读入测试用例数据并把测试结果写回

set nocount on
if not exists(select * from master.dbo.sysdatabases where name='DbTestCasesAndResults')
 raiserror('Fatal error:dbTestCasesAndResults not found',16,1)
go

if exists(select * from sysobjects where name='tap_Reset')
 drop procedure tap_Reset
go

create procedure tap_Reset
as
 truncate table dbEmployees.dbo.tb1Employees

insert into dbEmployees.dbo.tb1Employees values('e11','Adams','10/25/2009')
insert into dbEmployees.dbo.tb1Employees values('e22','Baker','10/12/2009')
insert into dbEmployees.dbo.tb1Employees values('e33','Young','06/15/2001')
insert into dbEmployees.dbo.tb1Employees values('e44','Zetta','08/15/2003')

--其他数据在此处插入
exec tap_Reset
go

declare tCursor cursor fast_forward
 for select caseID,input,expectedChecksum
  from DbTestCasesAndResults.dbo.tb1Testcases
  order by caseID

declare @caseID char(4),@input datetime,@expectedChecksum int
declare @whenRun datetime
declare @resultMsg varchar(80)
declare @actualChecksum int

create table #resultRowset --for checksum technique
(
 empID char(3) primary key,
 empLast varchar(35) not null,
 empDOH datetime not null
)

set @whenRun = getdate()

print 'stored procedure under test = usp_HiredAfter'
print ' '
print 'CaseID Input Expected Actual Result'
print '==========================================='

open tCursor
fetch next
 from tCursor
 into @caseID,@input,@expectedChecksum

while @@fetch_status=0
begin
 exec tap_Reset --reset test bed data
 truncate table #resultRowset --empty out the result rowset
 insert #resultRowset(empID,empLast,empDOH) --call sp under test
 exec dbEmployees.dbo.usp_HiredAfter @input
 
 if(@@rowcount=0)
  set @actualChecksum=0
 else
  select @actualChecksum=checksum_agg(binary_checksum(*)) from #resultRowset
  
 if (@actualChecksum=@expectedChecksum)
  begin
   set @resultMsg=@caseID + ' ' + cast(@input as varchar(11)) +

  end
 fetch next

end

close tCursor
deallocate tCursor

drop table #resultRowset
