数据迁移中的数据测试

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：

1. 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 TestDatabaseGOIF OBJECT_ID ('dbo.AccountID', 'P') IS NOT NULL     DROP PROCEDURE dbo.AccountIDGOCREATE PROCEDURE dbo.AccountIDASBEGIN        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 '00000000%')         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   ENDGO--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。
