The LoadTestUserContext type exposes the following members.

Properties

	Name	Description
	CompletedTestCount	Gets or sets the number of tests that have been completed by the virtual user that is represented by the LoadTestUserContext object since the start of the load test.
	Count	Gets the number of elements that are contained in the LoadTestUserContext object.
	InitializeTestContext	Gets or sets the state of the user context at the time InitializeTest was completed for the virtual user that is associated with the LoadTestUserContext object.
	IsNewUser	Gets a value that indicates whether a newly created virtual user is running the current test.
	IsReadOnly	Gets a value that indicates whether LoadTestUserContext is read-only.
	Item	Gets or sets a LoadTestUserContext element that has the specified key.
	Keys	Gets an ICollection that contains the keys of the LoadTestUserContext elements.
	ScenarioName	Gets or sets the name of the load test scenario that created the virtual user that is represented by this LoadTestUserContext.
	UserId	Gets the UserId of the user in the load test scenario.
	Values	Gets an ICollection that contains the values in the LoadTestUserContext elements.

Methods

	Name	Description
	Add(KeyValuePair<String, Object>)	Adds a KeyValuePair item to the LoadTestUserContext.
	Add(String, Object)	Adds an element that has the provided key and value to the LoadTestUserContext.
	Clear	Removes all items from the LoadTestUserContext.
	Contains	Determines whether the LoadTestUserContext contains a specific value.
	ContainsKey	Indicates whether the LoadTestUserContext contains an element that has the specified key.
	CopyTo	Copies the elements of the LoadTestUserContext to an Array, starting at a particular Array index.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	Returns an enumerator that iterates through the LoadTestUserContext.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	Remove(KeyValuePair<String, Object>)	Removes the first occurrence of a specific object from the LoadTestUserContext.
	Remove(String)	Returns a value that indicates whether the first occurrence of a specific object must be moved from the LoadTestUserContext object.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetValue	Gets the value that is associated with the specified key.

Remarks

LoadTestUserContext encapsulates information about the user context in which a test is running in a load test.

Examples

The code for a unit test that runs in the context of a load test can obtain a reference to the LoadTestUserContext for the virtual user that runs the unit test by using the key "$LoadTestUserContext" when the user accesses the TestContext properties.

For example:

    LoadTestUserContext loadTestUserContext = 
        this.TestContext.Properties["$LoadTestUserContext"] 
        as LoadTestUserContext;

Similarly, a coded Web test can access the LoadTestUserContext as follows:

    LoadTestUserContext loadTestUserContext = 
        this.Context["$LoadTestUserContext"] as LoadTestUserContext;

When the unit test or Web test runs outside the context of a load test, the LoadTestUserContext that is returned by the preceding code is nulla null reference (Nothing in Visual Basic).

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.
