TestCleanupAttribute 建構函式
初始化 TestCleanupAttribute 類別的新執行個體。

範例
SampleClassLib 命名空間包含 DivideClass 類別,這個類別則包含我們所要測試的方法。 這個方法稱為 DivideMethod()。
using System;
using System.Collections.Generic;
using System.Text;
namespace SampleClassLib
{
public class DivideClass
{
public int DivideMethod(int a)
{
return 2 / a;
}
}
}
Imports System
Imports System.Collections.Generic
Imports System.Text
Namespace SampleClassLib
Public Class DivideClass
Public Function DivideMethod(ByVal a As Integer) As Integer
Return 2 \ a
End Function
End Class
End Namespace
在下列程式碼中,DivideClassTest 測試類別包含稱為 DivideMethodTest 的測試方法。 這個程式碼也包含控制方法、類別和組件之初始化及清除執行順序的屬性。
請特別注意 Cleanup() 方法上的 TestCleanup 屬性。
