Few of the key differences between reusable actions and
functions here.
Passing Data
Actions - can only accept primative data types as
parameters (strings, integers, etc)
Functions - can accept arrays, dictionary objects and test
objects (i.e. Pages, Frames, WebRadioGroups, etc.)
Resource Usage
Actions - For each action, there’s a folder, three separate
vbs files, a local Object Repository, a subfolder
containing snapshots, an Excel spreadsheet, and a few
seconds of load time.
Functions - There’s the code contained in the Function, and
that’s all
API
Actions - You cannot insert calls to Existing Actions
through the QTP API, you can only do it through the
interface
Functions - You can attach Function Libraries to Test
Scripts through the QTP API
Return Values
Actions - Return values are difficult to understand and
read in the syntax
Functions - Return values work like they do in other
languages (i.e. as lvalues)
