Declare a Variable, Variable
Declaration in automation testing with Example in QTP
How will you declare a variable in
QTP ?
Variable can be declare using a Keyword DIM .
With the help of SET keyword value also can be
assign to variable.
Example.
Dim tempt ' It Will declare the variable named tempt
Set tempt = 30 ' It Will assign a value 30 to tempt
Variable Declaration:
.There are following 3 ways to declare the variable:
- Dim Statement
- Public Statement
- Private Statement
We can understand it with the help of following example:
Dim Nos_Passenger
We can declare multiple variables by just separating the each
variable name with comma
i.e. Dim Right, Left, Top, Bottom
Implicit Declaration: Variable can be declare implicitly
also, Simple you need to use it name in available scripts. It is not
good style because There is high chance of misspell on multiple paces
reason of unexpected result when our scripts will run.
Due to this Reason, The Explicit
Option statement is available to mandatory explicit declaration for
all type of variables. The Option Explicit statement should be the
first statement in your script.
Note:
As you know that The Dim keyword is
used to declare the variables at the script level for all procedure
with in the script level. And at procedure level, Variables are
available only with in the procedure.
Public Statement variable can be
access and used for all type of procedures in all scripts.
Private Statement variable can
be access and used only for private procedures in any single script.
Where these are declared.
