数据迁移中的数据测试 推荐

很久没有写自己的blog了。自动化测试项目结束后，又参加了一些新项目，有些和测试自动化无关。目前做的是数据迁移测试，即把一个老系统的业务数据，迁移到新系统中。大部分测试都集中在数据的测试，主要根据BMD测试数据字段的对应关系。测试用例都是用SQL脚本写的。为了调用这些测试用例，也写了一个简单的测试框架，思路如下：
Main.sql

这个文件有两部分，
1） 生成一个TestResult表，记录每一个测试用例的结果，如：

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TestResult]') AND type in (N'U'))
DROP TABLE [dbo].[TestResult]
BEGIN
CREATE TABLE [dbo].[TestResult](
[ResultId] int identity(1,1) NOT NULL,
[TestCaseId] nvarchar(255) NOT NULL,
[ProcedureName] nvarchar(255) NOT NULL,
[TestCaseResult] nvarchar(255) NOT NULL,
[TestLog] nvarchar(max) NULL,
[ExecutionTimeStamp] datetime NULL
)

INSERT INTO [dbo].[TestResult]
VALUES

('C-301','AccountID','NOT RUN','',CURRENT_TIMESTAMP),
......
END

2） 调用每一个测试用例对应的存储过程。

EXECUTE C_AccountID

2. 每一部分数据都有自己的文件，如Account.sql. 在这个文件里，包括了将测试用例自动化的存储过程。Example:

--C-301--------------Start of AccountID Procedure-------------------
USE TestDatabase
GO
IF OBJECT_ID ('dbo.AccountID', 'P') IS NOT NULL
DROP PROCEDURE dbo.AccountID
GO

CREATE PROCEDURE dbo.AccountID
AS
BEGIN
DECLARE @AccountIDCount int
DECLARE @DupCount int
DECLARE @LegalCount int
DECLARE @Result nvarchar(10)
DECLARE @Comments nvarchar(255)
/* Test the account id's mapping */
SET @AccountIDCount = 0
SET @AccountIDCount = (SELECT COUNT(*) FROM [MasterData] T LEFT JOIN [TargetList] S
ON CAST( T.[iAccountID] as nvarchar) =  CAST( S.[PARTYID] as nvarchar) collate Latin1_General_CI_AS
WHERE T.[iAccountID] IS NULL )
/* Check there is no duplicate account id */
SET @DupCount = 0
SET @DupCount = (SELECT COUNT(*) FROM  [MasterData] WHERE (iAccountID in (select iAccountID from [MasterData] group by iAccountID having count(*)>1) ))

/* check the account id is 10 digits */
SET @LegalCount = (SELECT * FROM [Rex_DCL5_LDS_Customer_STG_MasterData] WHERE iAccountID not like '%0000000000%')

IF @AccountIDCount + @DupCount + @LegalCount= 0
BEGIN
SET @Result = 'PASS'
SET @Comments = '[iAccountID] are correct.'
END

ELSE
BEGIN
SET @Result = 'FAIL'
SET @Comments = 'There are: ' + CAST(@AccountIDCount as nvarchar) + 'records of T data are not contained in S data.'+
CAST(@DupCount as nvarchar) + ' records are duplicated' +
CAST(@LegalCount as nvarchar) + ' records are illegal'
END

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TestResult]') AND type in (N'U'))
BEGIN
UPDATE [dbo].[TestResult]
SET TestCaseResult = @Result,
TestLog = @Comments,
ExecutionTimeStamp = CURRENT_TIMESTAMP
WHERE ProcedureName = 'AccountID'
END
END
GO
--C-301------------End of dbo.AccountID Procedure-------------------

执行测试是，先Acount.sql，生产每一个测试用例的存储过程，然后在打开Main.sql去调用这些存储过程。
这个框架本身非常简单，很容易扩展和维护，为进行数据迁移测试的童鞋们，抛砖引玉。
