    You CAN do a POM, but the code is going to probably be more complicated than you want.  NameMapping is what is basically the replacement for POM in Silenium.  All your main actions (click, keys, etc) are on the Alias objects themselves so you don't need, really, to create classes for each of the different objects.  You just need to use NameMapping or one of those other methods that I suggested for building your objects.

So basically there is no such a way to implement standard POM in here, and the best way to store objects is the Name Mapping?

Hi,

As Robert wrote.

But not NameMapping but Aliases. Aliases, actually, is a far more handy and functional analogue of POM in TestComplete.

One more note:

When you are using POM in Selenium, you are instantiating POM class on the given page/form test start and dispose it of when the page/form is closed/navigated away.

Aliased object in TestComplete is not disposed of after it is assigned to a variable but is cached and TestComplete tries to re-use it later. This will result in the 'Object not found error' (analogue of the Stalled Object Reference exception in Selenium) if some object has been recreated after the first use. .RefreshMappingInfo() method solves this problem, but it is expensive and must be used only when really unavoidable.

To sum up: pure classical POM is not a recommended way of test code development in TestComplete's world in favor of properly crafted Aliases tree. (And, quite probably, dynamic search via .FindXXX() methods that use some Aliased object as a search root. And such dynamic search well may be implemented as a set of POM-like functions.)
