.NET—Spring.NET保持数据现场测试

.NET—Spring.NET保持数据现场测试

解：

这个版本提供两种方式进行测试：1、破坏现场测试；2、恢复现场测试

Nunit2.5.5与VS2008集成

赵海燕

20160625

关键点，配置文件实现bean注入初始化，AdoTemplate可以直接取数据库数据，前一个实现控制反转，后一个是ADO.NET的封装。

1.2 项目结构：



1.3 AccountManager

黄色为启动事务；构造函数时注入。

using System;

using System.Data;

using Spring.Transaction;

using Spring.Transaction.Interceptor;

using Spring.TxQuickStart.Dao;

namespace Spring.TxQuickStart.Services

{

public class AccountManager : IAccountManager

{

private IAccountCreditDao accountCreditDao;
private IAccountDebitDao accountDebitDao;

private float maxTransferAmount = 1000000;

public AccountManager(IAccountCreditDao accountCreditDao, IAccountDebitDao accountDebitDao)
{
this.accountCreditDao = accountCreditDao;
this.accountDebitDao = accountDebitDao;
}

public float MaxTransferAmount
{
get { return maxTransferAmount; }
set { maxTransferAmount = value; }
}

// The following rollback rule will result in commiting of only work done
// by the CreateCreate DAO method.  The exception is still propagated out to the
// calling code.

// [Transaction(NoRollbackFor = new Type[] { typeof(ArithmeticException) })]

[Transaction(TransactionPropagation.Required)]
public void DoTransfer(float creditAmount, float debitAmount)
{
accountCreditDao.CreateCredit(creditAmount);

if (creditAmount > maxTransferAmount || debitAmount > maxTransferAmount)
{
throw new ArithmeticException("see a teller big spender...");
}

accountDebitDao.DebitAccount(debitAmount);
}

}

}

1.4 application-config.xml

黄色为初始化注入

1.10 使用nunit2.5.5

在vs2008中集成nunit

\vmware-host\Shared Folders\F\软件安装包\单元测试\ NUnit-2.5.5.10112.msi

在一个类库的项目新建一个类，加入如下代码：

using System;

using System.Collections.Generic;

using System.Text;

namespace Spring

{

class Program

{

static void Main(string[] args)

{

}

}

}

修改项目属性：







在VS2008选中测试项目直接启动，就可以启动nunit



设置好nunit为当前项目exe所在路径，就可以进行断点调试了。
