What is the exact difference bet function and action in QTP
Anybody can explain it in detail..Thanks in advance..

Answer Posted / paresh patel

1. Action is a QTP Feature. Function is a VBScript/JScript
Feature.
2. Actions can return multiple outputs. Function can return
only one output.
3. Actions can have only basic data type (String, Number,
Boolean, Date, Password, Any) as input & output parameters.
Where 'Any' is a variable type data. Functions can have
basic Data Types, Object Data Types as well as Array
Variables as Input Arguments and Output value.
4. Function is a code block stored in a Text Type File.
Action is stored as a Folder and has many other entities
like data-table, object-repository associated with it.


Note:
1. Both Action and Functions are block of code.
2. You can call Function in an action, By associating its
file to QTP Script. You can aslo have QTP features called in
a Function, i.e. you can also call an Action in a function.
However, that Function can only used by QTP.
