Test identity action (dictionary item)
For automation interface information about a Test Identity Action, see Action node (automation interface). For automation interface purposes, a Test Identity Action is an Action Node that has its Node Type set to Test Identity Action.
A Test Identity Action is an action that tests if two values are identical objects. This action returns true if the two input values are the same identity, false if they are not.
Create a Test Identity Action through a Modeler explorer pane or an Activity Diagram:
• In a Modeler pane, right-click an Activity or Structured Activity Node, and select New > Action Node > Test Identity Action.
• On an Activity Diagram: click the Test Identity Action button, and then click in free space or inside an Activity Partition, Interruptible Activity Region or Structured Activity Node.
To access the Test Identity Action button, click the arrow next to the Read Self Action button and then select Test Identity Action button.
On creation of a Test Identity Action, Modeler creates two Input Pins and an Output Pin:
• The two Input Pins are named First Input Pin and Second Input Pin.
• The Output Pin is named Result Pin, and its data type is set to a Type Definition named Boolean (if required, Modeler creates this Type Definition).
You cannot delete the Output Pin or Input Pins, and you cannot create any other Output Pins or Input Pins on a Test Identity Action.
When used on an Activity Diagram, a Test Identity Action's notation is as follows.
The View Options on an Activity Diagram allow you to show or hide the Name, Action Type and Linked Item Name (not applicable). By default, the Action Type is shown. The view options are set through the Action Node entry. See Action node view options - activity diagram.
On an Activity Diagram, you can populate a Test Identity Action's missing Activity Flows, Output Pins, Comments and Constraints: right-click the Test Identity Action, select Populate, and then click the appropriate command.
In the Dictionary pane, Test Identity Actions are listed in the UML\Action Nodes folder.
In the Modeler panes, a short-cut symbol on the Test Identity Action's icon indicates that the item is a stub.
The following sections provide information about how a Test Identity Action is used in the model.
Properties
In addition to the standard properties a Test Identity Action has these properties:
Owned by
Activity — The Activity that scopes the Test Identity Action.
Structured Activity Node — Applies only when the Test Identity Action is scoped directly to a Structured Activity Node.
Owns
Comment
Constraint
Control Flow — The Control Flow is owned jointly by the Test Identity Action and the associated item. The access permissions you have to a Control Flow are determined by the access permissions you have to its source item.
Dependency — The Dependency is owned jointly by the Test Identity Action and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.
Exception Handler — The Exception Handler is owned jointly by the Test Identity Action and the associated item. The access permissions you have to an Exception Handler are determined by the access permissions you have to its source item.
Input Pin — Only the Input Pins that Modeler creates on creation of the Test Identity Action.
IO Flow — The IO Flow is owned jointly by the Test Identity Action, the IO Flow's other linked item and the IO Flow's IO Item.
Output Pin — Only the Result Pin that Modeler creates on creation of the Test Identity Action.

In addition to the owning Activity or Structured Activity Node, a Test Identity Action can be linked to the following items.
Stereotype — To make a Test Identity Action valid for a Stereotype, set up Action Node a valid item type.

Like most other items in a Model, a Test Identity Action can be linked to an Activity Partition, Comment, Frame Box, General Node, General Flow, General Flow Diagram Node, Constraint (applied), General Flow Diagram Flow or Swimlane.
