About Image Set Editor

Applies to TestComplete 15.65, last modified on July 17, 2024

You use the Image Set editor to view and manage images that you use in your image-based tests.

Note: The Image Repository does not store images for region checkpoints. Data for the latter is stored in the Stores | Regions collection.

Here is a sample view of the editor:

Information on the Editor

Items List

The Items list on the left of the editor lists items (images) in the selected image set. Typically, these items correspond to tested controls or screen areas in your application. The item name identifies the item in tests.

Note: If you change the item name, TestComplete will suggest updating the Image Touch and Image Based Action operations in your keyword tests automatically. If you have other operations that use the item, or if you use the item in script tests, update them manually.
Image Strip

The way the controls and areas in tested applications look like depends on various factors like a color scheme, application UI style, screen resolution, and so on. To allow your test to find the needed control or screen area regardless of those factors, you can associate several images with an item.

The Image Strip shows all the images associated with the selected item.

In your image-based tests, to simulate an action over an item, TestComplete will check all the images associated with the item until it finds the one that matches.


The Preview area shows the image currently selected in the Image Strip.

It shows the PC or mobile device screen and the recognition area on it. The recognition area indicates the region used for image-based recognition of your tested control. When in your test you address the control, TestComplete will search for the area on the screen.

The recognition area is highlighted with a red frame.

You can adjust the bounds of the area to improve the control recognition. For example, sometimes, a control’s image may include minor elements that make it difficult to recognize the control on the screen, like a caret in edit boxes. You can exclude these problematic details from the recognition area by moving the area borders.

Item Properties

To adjust the control recognition in tests, you can also use a number of properties the editor shows on the right.
