The TestPropertyAttribute type exposes the following members.

Constructors

	Name	Description
	TestPropertyAttribute	Initializes a new instance of the TestPropertyAttribute class with values for the Name and Value properties.

Properties

	Name	Description
	Name	Gets the name of the test property.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
	Value	Gets the value of the test property.

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	System#Runtime#InteropServices#_Attribute#GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

To see a property, first rebuild the project and then highlight the test in the Test List Editor or the Test View window. The property is viewable in the Properties pane after the project is rebuilt.

This attribute can be specified on a test method. There can be multiple instances of this attribute to specify more than one item.

Examples

The following example shows how to access TestProperty properties from within the MyTestMethod() method.

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Windows.Forms;
using System.Reflection;

namespace TestProperty
{
   [TestClass]
   public class TestPropertyTest
   {
      [TestMethod()]
      [TestProperty("MyProperty1", "Big")]
      [TestProperty("MyProperty2", "Small")]
      public void MyTestMethod()
      {
         // Get the current type
         Type t = GetType();

         MethodInfo mi = t.GetMethod("MyTestMethod");
         Type MyType = typeof(TestPropertyAttribute);
         object[] attributes = mi.GetCustomAttributes(MyType, false);

         for (int i = 0; i < attributes.Length; i++)
         {
            string name = ((TestPropertyAttribute)attributes[i]).Name;
            string val = ((TestPropertyAttribute)attributes[i]).Value;

            string mystring = string.Format("Property Name: {0}, Value: {1}", name, val);
            MessageBox.Show(mystring);
         }
      }
   }
}

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
