Functions
⇒Sub procedure:
Sub: Declares the name, arguments and code that form the body of a Sub procedure.
Syntax:
Sub name [(arglist)]
[statements]
[Exit Sub]
[statements]
End Sub
Arguments:
Sub: Declares the name, arguments and code that form the body of a Sub procedure.
Syntax:
Sub name [(arglist)]
[statements]
[Exit Sub]
[statements]
End Sub
Arguments:
Public: | Indicates that the Sub procedure is accessible to all other procedures in all scripts. |
Default: | Used only with the Public keyword in a Class block to indicate that the Sub procedure is the default method for the class. An error occurs if morethan one Default procedure is specified in a class. |
Private: | Indicates that the Sub procedure is accessible only to other procedures in the script where it is declared. |
name: | Name of the Sub; follows standard variable naming conventions. |
arglist: | List of variables representing arguments that are passed to the Sub procedure when it is called. Commas separate multiple variables. |
statements: | Any group of statements to be executed within the body of the Sub procedure. |
Example:
Addition 5 , 4 Sub Addition( num1,num2) Result=num1+num2 Msgbox "The Sum of the numbers is " & Result End Sub
⇒Function:
Declares the name, arguments, and code that form the body of a Function procedure.
Syntax:
Function name [(arglist)]
[statements]
[name = expression]
[Exit Function]
[statements]
[name = expression]
End Function
Arguments:
Declares the name, arguments, and code that form the body of a Function procedure.
Syntax:
Function name [(arglist)]
[statements]
[name = expression]
[Exit Function]
[statements]
[name = expression]
End Function
Arguments:
Public: | Indicates that the Function procedure is accessible to all other procedures in all scripts. |
Default: | Used only with the Public keyword in a Class block to indicate that the Function procedure is the default method for the class. An error occurs ifmore than one Default procedure is specified in a class. |
Private: | Indicates that the Function procedure is accessible only to other procedures in the script where it is declared or if the function is a member of aclass, and that the Function procedure is accessible only to other procedures in that class. |
name: | Name of the Function; follows standard variable naming conventions. |
arglist: | List of variables representing arguments that are passed to the Function procedure when it is called. Commas separate multiple variables. |
statements: | Any group of statements to be executed within the body of the Function procedure. |
expression: | Return value of the Function. |
Example:
Result=Addition(5,4) Msgbox "The sum of the number is " & Result Function Addition( num1,num2) Addition=num1+num2 End Function
⇒Call:
Transfers control to a Sub or Function procedure.
Syntax:
[Call] name [argumentlist]
Arguments:
Transfers control to a Sub or Function procedure.
Syntax:
[Call] name [argumentlist]
Arguments:
Call: | (Optional) keyword, If specified, you must enclose argumentlist in parentheses. |
name: | (Required) Name of the procedure to call. |
argument list: | (Optional) Comma-delimited list of variables, arrays, or expressions to pass to the procedure. |
Example:
'Call a Sub procedure Call Addition(5 , 4) Sub Addition( num1,num2) Result=num1+num2 Msgbox "the Sum of the numbers is " & Result End Sub
⇒Function Library & Associating Function library to a Test
Different Types of Library files
Different types of library files are ".qfl" files,".Vbs" files
Steps to follow to create Function Library:
1. Functions are created manually:
File-->New-->Function library(Enter the functions)
2. Save the functions:
File--> Save (File is saved as .qfl file)
3. Associating Function library to a Test:
Test --> Settings --> Choose Resources tab --> Choose + button so select the ".qfl" file --> browse and select the ".qfl" file -->
click OK.
How to use library files in QTP & how we can call these files in to script?
We can load the external Library files by using 2 ways:
1. Choose Test --> Settings --> Choose Resources tab --> Choose + button so select the library file --> browse and select the
library file --> click OK.
2. We can load the library files using Scripting:
Use execute file function to load library files:
Step1. Open a notepad and paste the below function
Example:

2. We can load the library files using Scripting:
Use execute file function to load library files:
Step1. Open a notepad and paste the below function
Example:
'Code in External Library file(sample.vbs file). function SumOfTwoNumbers(a,b) Dim sum sum=a+b SumOfTwoNumbers=sum End Function
Step2. Save the notepad as a .vbs file(sample.vbs) in path "D:\Sample.vbs"
Step3. Paste the below code in QTP and execute,You will find that the below code access function from the "sample.vbs" file
Example:
executefile "D:\Sample.vbs"
x=10
y=5
result=SumOfTwoNumbers(x,y)
msgbox result
