Reusable Action is peice of code that perform an action on

the application , which has application logic.

On the other hand , Functions does not have the application

logic . It performs a specific action on the data retrieved

from the application and returns the result to the calling

action.

For Ex: Your application has TextBox and Button,

Input : In the textbox we need to enter a numeric value

say 5.

Action : Calculate the Factorial

Expected : Factorial value should be displayed in the

textbox.

Here setting a value to textbox , performing the click

operation and corresponding verification is maintained in

the Action , calculation of the factorial value to arrive

at the expected output we use a Function.

Answer / buvan

Action can contain Object Repositary, Data Table and Active
Screen etc....

Function doesn't have these features

Action is Internal to QTP

Function is Just Lines of code.

Action Can/Can't be Resuable

Functions are always Resuable

Action Paramenter have default values

Function don't have any default value

Action parameter type are ByValue

Functions can be passed ByRef

Action can have multiple returning values

Function can return only single value

Answer / deven

♦It returns single value.
♦ we can call functions within actions but we can't call
actions within functions

♦ Generally functions are saved with ".vbs" extension
whereas actions will save with ".mts".

♦ Every Action will have its own Datatable whereas function
does not.

♦ Action can have a object repository associated with it
while a function can't. A function is just lines of code
with
some/none parameters and a single return value while an
action can have more than one output parameters.

♦ Action can contain Object Repository, Data table, Active
screen etc. whereas function do not have these features.

♦ Action is internal to QTP whereas Function is just lines
of code with some/none parameters and a single return value.

♦ Action can/cannot be resuable whereas functions are
always reusable.

♦ Action Parameter have default values whereas VB script
functions do not have any default values.

♦ Action parameter type are byvalue only where vbscript
functions can be passed byref.

♦ Action can have multiple output(returning) values whereas
function can return only single value.

Answer / uday kumar_anem

Both Actions and Functions are used to access a peace of
code, that is frequetly used.

The main difference is :
Functions have only application logic, means that we dont
have access to the resources of a test.
For ex: we need to write a script to access Object
Repository, Data Table etc....

Actions also have application logic and the resources
associated with that action.

For Ex:
Say if you want to call a function, here you need to pass
function name and all other resources like(OR, Data Table
etc...).
Where as if you call an action, all these resources come
with action(based on the type of the action).

Answer / ram balamuri

Action is internal to QTP whereas functions are generic and
are coded in VBscript. The main difference between an
action and a function is that "an actions contains an
Object repository." An action can also be shared; it can
also use different shared reposiroties. A function on the
other hand doesn't have an object repository and is just
merely a code that returns some desired value(s).

Answer / mohammed

The Main differeence between Action And Function

1
1)Action is having it's own Objecr repositary ,datasheet in
datatable and also in results window action is having it's
own node.
2)Action execuetes it self.
3)Action is slow in execution.

1)Function is not having his own OR and datasheet in
datatable.
2)Function executes from action only.
3)Functions are faster in execution.

Kindly let me know any Mistakes.
Thank you.
