When testing UI applications, specially web apps, we frequently encounter the problem of window title changing with the state of the app or operations done on the app. For instance, when checking web mail, the title of the page could read “Inbox(35) - Microsoft Internet Explorer” where 35 really represents the number of unread email in your inbox. Now, when I open it at any other time, it might read “Inbox(36) - Microsoft Internet Explorer” based on unread mail. For GUI testers, this poses a problem since object identification works usually on the basis of window title and the title changing each time I run the test causes object identification to fail. :(
To solve this problem, the API of VSTS 2010 has a “Smart Match” feature built into it. Thej Kumar is our smart young developer that works on the record and play engine of Team Test and today, he will explain how smart match works. So, here you go:
How does the heuristic work:
Special case for MDI windows:
Good things to do regarding titles to ensure smart match picks works correctly:
Sometimes on a rare occasion, smart match does end up being oversmart ;-) and gives false positives, but those scenarios can be worked around. Tell us what you think of smart match!
