Desktop Applications

Learn Window Title

If you test the application via UIAutomation library then you can learn window title and use GetWindowText.

var text = SeS('UIAutomation').GetWindowText();

Using any Child Control

If you recorded/learned at least one child control of a window you can use it to read the window title. This method works with desktop applications of any kind (including Managed),

var text = SeS('_1').getDesktopWindow().Text;

Web Applications

To get a title of the current page invoke GetPageTitle for any element on the page.

var text = SeS('Home').GetPageTitle();
