Well, this is the most important to ask. We designed Tellurium Engine for the following reasons:
1) Focus on UI module, not individual UI element. 2) Implement the UI group locating on the Engine side because it is very inefficient to do group locating at Tellurium core side due to many round trip calls. 3) Users can access UI objects from the Engine instead of the DOM elements. The UI objects give users more abstraction and easier to use. For instance, if you get back the Table object, you can get table row number directly by calling the getTableRowNum method on the object. 4) Speed performance improvement, once the UI module is located, you can get the cached DOM reference without locating it for each call. 5) Improve test robust by using UI module partial matching. 6) Make it easier to export Tellurium to other languages because many functionalities are moved to Engine. 7) Process multiple commands by using Macro commands 8) In the future, we may also be able to move Javascript events to Engine so that Tellurium Engine automatically adds additional events. 9) Easier for Tellurium widget implement because the widget can access the DOM directly. 10) Some other reasons.
