Image recognition using TestComplete™ Testcomplete™ can be used to automate testing of Web & windows applications. Although TestComplete™ supports major standard controls, windows and objects in a wide variety of applications, there are some controls and windows that cannot be recognized by Test Complete directly. For example cells in few grid controls, buttons in some flash applications may not be accessible by TestComplete™. Handling TestComplete™ during such conditions makes automation little challenging. It is possible to overcome these kinds of difficulties by using a low-level recording approach to test such applications. The main drawback of such an approach is that the script will require several changes even for a simple UI change in the application. So, creating and maintaining a stable script with this method is also not possible. Low-level Recording will be usually used in TestComplete™ for automating Testing in browsers other than IE and Firefox. Any application that needs to be tested in other browsers (such as Google Chrome or Opera) using TestComplete™ automation needs to approach low level recording technique. You can also look at utilizing Image recognition feature of TestComplete™. Let‟s consider a test application containing a button which is unfortunately not recognized by TestComplete™. In this situation, it is possible in TestComplete™ to capture the image of this button and give it as an input for testing. TestComplete™ will search for this button using its image & recognize the button as a rectangular image object. Now we can get the position of the button and calculate X-Y coordinates of the center point of this object. By getting these coordinates, the action CLICK can be performed to trigger the click action of the mouse. To click a button,

How to find an Image in an object? One needs to use the method named „Regions.Find‟ inorder to find the image of object (which is not auto recognized by TestComplete™). Following is the syntax for this method Regions.Find(PictureTosearchin, PictureToSearchFor) This method searches for an image on other image or object. And it returns the identified rectangular image object. It has two required parameters. PictureToSearchin – Page or Window object, in which the object is located. PictureToSearchFor – This is the image name of the Test Object. This image should have been stored in Regions Items of Testcomplete™. Consider an example to explore usage of Image Recognition in TestComplete™. The following screenshot shows an Add-on that needs to be installed from Google Chrome. User needs to click button “Add to Chrome” inorder to install add-on from Google Chrome

browser.
Since Google Chrome is not currently supported by TestComplete™, we can make use of image recognition feature available in TestComplete™ to trigger the Button click action automated from Google Chrome browser, by identifying the position of the button and triggering click action on it 1) Store the rectangular image of this button in Region items of test complete project. In the below example, Image name is stored as „Add_To_Chrome‟
2) To find & click this image object on chrome window, we can use the following script.

3) This button clicks on the center position of the button.
Hence using the above script, TestComplete™ can automate the test for clicking button „Add to Chrome‟ executed from Google Chrome browser. Using the same method, it is possible find any unrecognized object and then can perform any actions on the recognized images.
