Answer / vijay

Actions can Return mutiple values, where as function will
return one value
Check points insertion wont be possible in functions where
it can be possible in Actions .
functions can be called outside the tool , where as Actios
are called only within QTP
scripts written in higher version of qtp wont be compatable
with Actions , where as functions since they are not QTP
related can be work in any version

functions can be even written in notepad , wiht .vbs file
name

ex :

Public Function F1
msgbox(" I am function")
end function
call F1

run the code in notepad and verify

Actions concept i restricted to QTP only ..

Function -> it consists of Set of statements written to
achieve a particular task.

Answer / 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.

Answer / prem

Action- Action is nothing but a step performed by user.
Action is catagorized in two parts
Reusable action,usable action.

Function-In that action what functionality u r written to
check that function is working properly or not.
e:g - if you write a script for the login page,the total
script is written for the login page is a action,and the
script was written for the login page is the
function,because main functionality in the script is login
the page.
