KeywordTests is the predefined name of the top-level object that provides access to a collection of keyword tests. To access the object, you must have the Keyword Tests collection added to your project. See Adding and Removing Project Items and Their Child Elements.
KeywordTest_Name is the name of the keyword test that is added to the Keyword Tests collection of your project and whose parameters you want to get. You can view the name in the Project Explorer panel.
