Image based recognition was first introduced in UFT (QTP) version 11.5, which enables the recognition of objects in Application Under Test (AUT) using “image” of the test objects instead of the properties of the object. This is also commonly known as Insight object identification as while working UFT needs to be in “Insight” mode. This can be useful to test controls from an application that UFT does not support or with some specific tests or required action for your tests. While experiencing Insight earlier, I cam across this youtube video of memory game which is a good example for its capabilities.
Insight is an image-based identification ability, to recognize objects in application based on what they look like instead of using properties that are part of design. UFT stores an image of the object with insight test objects and uses this image as main description property to identify object in the application.

In Insight mode, UFT stores the image of an object along with its ordinal identifiers in object repository. These objects are called as Insight Objects or Insight Test Objects. UFT stores ordinal identifier only if there are two objects with same look and feel exists, i.e. very similar images. These images becomes the main description property for UFT to identify objects.
You can also use Visual Relation identification for insight objects. It helps to improve object identification and avoid using ordinal identifiers. You also have flexibility to identify objects even if its not matching exactly the same. You just need to add “similarity” property to the test object description.
Adding Insight Objects
UFT provides two ways of adding insight objects either while recording or add insight objects directly into Object Repository (OR). While recording, you need to choose the recording mode as “Insight Recording”. In this mode, UFT records objects as insight object and store images for all the objects it cannot identify using appropriate add-ins. It captures the know identifiable objects in the usual way.
The other option is to directly add objects into OR using the “Add Insight Objects to Object Repository” button on toolbar. You can also use the menu option “Object > Add Insight Object to local”
While Adding Insight objects to OR, UFT provides two modes of learning objects – Manual and Automatic. Basic difference between both is just that how we define the object using boundaries. In Automatic mode UFT defines boundaries automatically while in Manual mode, you need to define boundaries specifically.
Adding Insight Objects in Automatic Mode
To use automatic mode, you need to select “Automatic” Mode and then point and click on the object you need to capture. UFT Captures and stores the image of the clicked object. There could be a case when UFT capture extra or unnecessary part of may be lesser part of the required object which capturing the image of the object. UFT provides option to exclude areas from captured image and save in OR.
Adding Insight Objects in Manual Mode
Manual Mode helps defining the boundaries of the object manually by dragging mouse and specifying the object area. Select “Manual” Learning Mode in “Select Learn Mode” dialog box.
UFT can use an ordinal identifier to create a unique description for the object.
Other aspects of object configuration, such as mandatory and assistive properties, and smart identification, are not relevant for Insight test objects.
Visual Relation Identifiers
You can also use visual relation identifiers to improve identification of the object
Add the similarity description property to the test object description.
This property is a percentage that specifies how similar a control in the application has to be to the test object image for it to be considered a match.
Scripting with Insight Object
Scripting with Insight object is easy and same as you script with any other object. Its just that in place of the test object name, you need to use the test object image. Action on the object can be different based on the type of the object.
When you hover over the cursor on the object in your code, you will be able to see the enlarged image of the object. By clicking on the image, you can go to the respective object in Object repository.
Settings/Options to work with Insight
To define options that customize how UFT handles insight object when creating test object and during the run session, UFT provides certain options settings.
Goto Tools> Options
Select “GUI Testing” tab
Select the node “Insight”
When Recording a test Object
Save the clicked coordinates as the test object’s ClickPoint – Check this option if you want to save the co-ordinates as click point for objects
When Running a Step
Display mouse operations – Check this option if you want to show the mouse click/drag operations on Insight Objects
Show test object image in steps – Check this option if you want to display Insight test object images in steps in the Editor. If cleared, UFT displays the test object names instead.
Display select learn mode dialog box – Check this option if you want UFT to display ‘Select Learn Mode’ dialog box. If this option is cleared, UFT no longer displays this dialog box on clicking
When Taking Snapshots
Limit test object image margin in snapshot – check this option to limit the snapshot size when adding a new Insight test object. The margin size can be specified in the Maximum pixels around the image box. If cleared, UFT includes the whole screen in the snapshot.
Maximum Pixels around the image – instructs UFT to include extra areas in the snapshot, based on the pixels mentioned.
Maximum Numbers of snapshots to save when recording a test – instructs UFT to limit the number of images it saves while recording the test in Insight mode.
