Description
Projects’s test items can be organized in a tree-like structure. A test item can have a number of child items. The ChildTestItem property returns the child test item specified by its index.
Declaration
ProjectTestItem_COMAccessObj.ChildTestItem(Index)
| Read-Only Property | A ProjectTestItem_COMAccess object |
| ProjectTestItem_COMAccessObj | An expression, variable or parameter that specifies a reference to a ProjectTestItem_COMAccess object | |||
| Index | [in] | Required | Integer | |
Applies To
The property is applied to the following object:
Parameters
The property has the following parameter:
Index
Specifies the index (zero-based) of the desired child test item. The total number of items is specified by the ChildCount property.
Property Value
An integer value that specifies the number of child items of the given test item.
Example
The following example demonstrates how to access the project’s test item collection from a Visual Basic or C# application. The sample code uses the ProjectTests_COMAccess object’s properties to obtain the ProjectTestItem_COMAccess objects that provide a program interface to the project test items. The example displays a tree structure corresponding to the project’s test item collection structure.
