说 明：该实例是最早期的nunit版本中找到，在测试驱动的开发中它并不是一个很好的例子，但它能阐明使用nunit的最基本方法。
现在开始我们的例子。假设我们开始写一个银行业的应用程序，我们有一个基类—Account，Account主要负责资金的增加，撤销和转帐，下面是该类的代码
namespace bank
{
public class Account
{ private float balance; public void Deposit(float amount) { balance+=amount; 
} public void Withdraw(float amount) { balance-=amount; } public void TransferFunds(Account destination, float amount) { } public float Balance { get{ return balance;} } }
}namespace bank{ using NUnit.Framework; [TestFixture] public class AccountTest { [Test] public void TransferFunds() { Account source = new Account(); source.Deposit(200.00F); Account destination = new Account(); destination.Deposit(150.00F); source.TransferFunds(destination, 100.00F); Assert.AreEqual(250.00F, destination.Balance); Assert.AreEqual(100.00F, source.Balance); } }}public void TransferFunds(Account destination, float amount){ destination.Deposit(amount); Withdraw(amount);}private float minimumBalance = 10.00F;public float MinimumBalance{ get{ return minimumBalance;}}public class InsufficientFundsException : ApplicationException{}[Test][ExpectedException(typeof(InsufficientFundsException))]public void TransferWithInsufficientFunds(){ Account source = new Account(); source.Deposit(200.00F); Account destination = new Account(); destination.Deposit(150.00F); source.TransferFunds(destination, 300.00F);}public void TransferFunds(Account destination, float amount){ destination.Deposit(amount); if(balance-amount < minimumBalance) throw new InsufficientFundsException(); Withdraw(amount);}[Test]public void TransferWithInsufficientFundsAtomicity(){ Account source = new Account(); source.Deposit(200.00F); Account destination = new Account(); destination.Deposit(150.00F); try { source.TransferFunds(destination, 300.00F); } catch(InsufficientFundsException expected) { } Assert.AreEqual(200.00F,source.Balance); Assert.AreEqual(150.00F,destination.Balance);} [Test][Ignore("Decide how to implement transaction management")]public void TransferWithInsufficientFundsAtomicity(){ // code is the same}
