Flex TabBar Support

Applies to TestComplete 15.65, last modified on July 17, 2024
Flash Player has reached end of life on December 31, 2020. Support for Flash and Flex applications is now deprecated in TestComplete and will be removed in a future release.
Information in this topic applies only to web tests that implement the classic approach. In cross-platform web tests, TestComplete recognizes third-party controls as standard web controls.

About Support

TestComplete can recognize Flex TabBar controls in Flex applications. It provides special properties and methods that let you retrieve the controls data and simulate user actions on the controls (see below).

Supported Versions

Supported component versions: Adobe Flex ver. 3.3, 3.4, 3.5, 3.6, 4.0, 4.1, 4.5, 4.6; Apache Flex ver. 4.9 - 4.14.


In order for TestComplete to be able to work with Flex TabBar controls, the following requirements must be met:

  • You must have an active license for the TestComplete Web module.

  • The control’s class name must be specified in the group of your project’s Object Mapping options. By default, this group contains the following items:

    • mx.controls::TabBar
    • spark.components::TabBar

    You can also command the test engine to recognize custom controls as Flex TabBar controls. See below for information about this.

  • Support for the Flex TabBar controls is implemented by the Web Testing plugin. This plugin is installed and enabled automatically as part of the TestComplete Web module.

    If you experience issues when working with the controls, select File > Install Extensions from the TestComplete main menu and check whether the plugin is active. (You can find the plugin in the Web group.) If the plugin is not available, run the TestComplete installation in the Repair mode.

Recognizing Custom Controls

Instances of the following classes and their descendants are recognized by TestComplete as Flex TabBar controls:

  • mx.controls::TabBar

  • spark.components::TabBar

If the class of your custom control is a descendant of one of the classes listed above, TestComplete recognizes your control as the Flex TabBar control automatically.


When testing Flex TabBar controls, you can use properties and methods specific to these controls, as well as properties and methods that TestComplete applies to onscreen objects. For the full list of available properties and methods, see the following topics:
