TestCleanupAttribute Constructor

Initializes a new instance of the TestCleanupAttribute class.

Namespace:  Microsoft.VisualStudio.TestTools.UnitTesting
Assembly:  Microsoft.VisualStudio.QualityTools.UnitTestFramework (in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll)

public TestCleanupAttribute()

The SampleClassLib namespace contains the DivideClass class, which in turn contains the method we want to test. This method is called DivideMethod().

using System;
using System.Collections.Generic;
using System.Text;

namespace SampleClassLib
{
   public class DivideClass
   {
      public int DivideMethod(int a)
      {
         return 2 / a;
      }
   }
}

In the following code, the DivideClassTest test class contains a test method called DivideMethodTest. This code also contains attributes that control the initialization and clean-up execution order for the method, class, and assembly.

In particular, note the TestCleanup attribute on the Cleanup() method.

using Microsoft.VisualStudio.TestTools.UnitTesting;
using SampleClassLib;
using System;
using System.IO;
using System.Windows.Forms;

namespace TestNamespace
{
   [TestClass()]
   public class DivideClassTest
   {
      [AssemblyInitialize()]
      public static void AssemblyInit(TestContext context)
      {
         MessageBox.Show("Assembly Init");
         }

      [ClassInitialize()]
      public static void ClassInit(TestContext context)
      {
         MessageBox.Show("ClassInit");
      }

      [TestInitialize()]
      public void Initialize()
      {
         MessageBox.Show("TestMethodInit");
      }

      [TestCleanup()]
      public void Cleanup()
      {
         MessageBox.Show("TestMethodCleanup");
      }

      [ClassCleanup()]
      public static void ClassCleanup()
      {
         MessageBox.Show("ClassCleanup");
      }

      [AssemblyCleanup()]
      public static void AssemblyCleanup()
      {
         MessageBox.Show("AssemblyCleanup");
      }

      [TestMethod()]
      [ExpectedException(typeof(System.DivideByZeroException))]
      public void DivideMethodTest()
      {
         DivideClass target = new DivideClass();
         int a = 0; 
         int actual;
         actual = target.DivideMethod(a);
      }
   }
}
