There is no limit to the number of actions that can be performed in a single test, though only 255 actions can include data tables. Descriptive programming methods like using regular expressions instead of constants and repository parameters can be used to create a dynamic object repository in QTP. Global sheets are used for test data that should be shared across all actions in a test, while action sheets are used to parameterize individual actions with independent test data.

1. 1. how many maximum actions can be performed in a single test -As many
ANS:-There is no limit. I have added up to 2000 actions. But only 255 actions
are having datatables.
2. How to create the dynamic object repository in QTP? Descriptive programming
ANS:-We can store the dynamic objects in OR using following methods:
- set the property values of object in OR using Regular Expression instead of constant
value
- use Repository Parameters to set dynamic property values for different tests or different
objects
3. What is difference between global sheet anh action sheet?
In QTP Datatable having Two types of Excel Sheets that are
1. Global Sheet
2.Action Sheet
Global Sheet is used for Global use, that means what you
entered in global sheet that should be used in any action
in the Test for example: test1 having 4action. at that
time you want to parameterize the some object in all
actions with same Test Data. at this times used global sheet
Action Sheet is used for local use, that means if you want
to parameterize the actions individually with independent
test data in test, at that time we are use Action Sheet
