點(diǎn)擊菜單“項(xiàng)目”->“添加類”，打開“添加新項(xiàng)”對(duì)話框，將名稱改為BookTest.vb或BookTest.cs、BookTest.jsl，然后點(diǎn)擊“添加”按鈕創(chuàng)建該類并修改代碼。VB代碼如下：
Imports NUnit.Framework
 
<TestFixture()> _
Public Class BookTest
Dim bo As Book = Nothing
 
<SetUp()> _
Public Sub Init()
Console.WriteLine("測(cè)試開始！")
bo = New Book
Console.WriteLine("book對(duì)象被初始化！")
End Sub
 
<Test()> _
Public Sub testId()
bo.id = "001" '設(shè)置id屬性的值為
'使用Assert查看id屬性的值是否為
Assert.AreEqual("001"， bo.id)
Console.WriteLine("id屬性被測(cè)試！")
End Sub
 
<Test()> _
Public Sub testName()
bo.name = "ASP" '設(shè)置name屬性的值為ASP
'使用Assert查看name屬性的值是否為JSP，這是個(gè)必然出現(xiàn)錯(cuò)誤的測(cè)試
Assert.AreEqual("JSP"， bo.name)
Console.WriteLine("name屬性被測(cè)試！")
End Sub
 
<TearDown()> _
Public Sub Dispose()
Console.WriteLine("book對(duì)象將被清理！")
bo = Nothing
Console.WriteLine("測(cè)試結(jié)束！")
End Sub
End Class
C#代碼如下：

Console.WriteLine("book對(duì)象被初始化！");
