UFT Tutorial 24

UFT Class 24

I) VBScript Operators
-------------------
a) Arithmetic Operators:

Arithmetic Operators return value based result.
---------------------------
1) Exponentiation ^

2) Multiplication *

3) Division /

4) Integer Division \

5) Modules mod

6) Addition

7) Subtraction

8) Concatenation
----------------------
Example:
Dim a, b, c
a = 10
b = 3

c = a ^ b
Msgbox c '1000

c = a * b
Msgbox c '30

c = a / b
Msgbox c '3.33333333

c = a \ b
Msgbox c '3

c = a mod b
Msgbox c '1

c = a + b
Msgbox c '13

c = a - b
Msgbox c '7

c = a & b
Msgbox c '103
------------------------------
+ Operator
-----------------
Dim a, b, c
a = 10
b = 3

c = a + b
Msgbox c '13

a = "10"
b = 3

c = a + b
Msgbox c '13

a = "10"
b = "3"

c = a + b
Msgbox c '103

a = "Hyderabad"
b = "123"

c = a + b
Msgbox c 'Hyderabad123

a = "Hyderabad"
b = "ABC"

c = a + b
Msgbox c 'HyderabadABC

a = "Hyderabad"
b = 123

c = a + b
Msgbox c 'Error
--------------------------------
& operator
-------------------
Dim a, b, c
a = 10
b = 3

c = a & b
Msgbox c '103

a = "10"
b = 3

c = a & b
Msgbox c '103

a = "10"
b = "3"

c = a & b
Msgbox c '103

a = "Hyderabad"
b = "123"

c = a & b
Msgbox c 'Hyderabad123

a = "Hyderabad"
b = "ABC"

c = a & b
Msgbox c 'HyderabadABC

a = "Hyderabad"
b = 123

c = a & b
Msgbox c 'Hyderabad123
------------------------------------
b) Comparison Operators (All are equal)
Comparison Operators return Boolean /logical (True or false) result.

1) =

2) <>

3) >

4) >=

5) <

6) <=
-------------------------------
Example:

Dim a, b, c
a =10
b =20

c = a = b
Msgbox c 'False

c = a > b
Msgbox c 'False

c = a >= b
Msgbox c 'False

c = a <> b
Msgbox c 'True

c = a < b
Msgbox c 'True

c = a <= b
Msgbox c 'True
-------------------------
c) Logical Operators

1) Not (Logical Negation)

Ex:
If Not Dialog("Login").Exist(3) Then
SystemUtil.Run "C:\Program Files\HP\Unified Functional Testing\samples\flight\app\flight4a.exe"
End If
Dialog("Login").Activate
Dialog("Login").WinEdit("Agent Name:").Set "asdf"
Dialog("Login").WinEdit("Password:").SetSecure "550787eda3b6ae2fc461b592b3778ebdc819e846"
Dialog("Login").WinButton("OK").Click
-------------------------------------
2) And (Logical conjunction)

Example:

Dim a, b, c
a = 100
b= 50
c =70

If a > b And a > c Then
    Msgbox "A is a Big Number"
    Else
    Msgbox "A is Not a Big Number"
End If
---------------------
Result Criteria for And Operator:
-------------
Exp1    Exp2    Result
------------------------
True    True    True
True    False    False
False    True    False
False    False    False
------------------------
3) Or (Logical Disjunction)
Result Criteria for Or Operator:
-------------
Exp1    Exp2    Result
------------------------
True    True    True
True    False    True
False    True    True
False    False    False
------------------------
4) Xor (Logical exclusion)
------------------------
Result Criteria for Xor Operator:
-------------
Exp1    Exp2    Result
------------------------
True    True    False
True    False    True
False    True    True
False    False    False
------------------------
VBScript Flow Control Statements
    Conditional Statements
    Loop Statements
--------------------------
II) VBScript Conditional Statements

> There are two types of Statements in VBScript

1) If statement

2) Select Case Statement
------------------
> Usage of conditional statements in UFT

1) To insert verification points

2) For Error handling
-------------------------------
> Types of Conditions

1) Single Condition (Positive / Negative Conditions)

Ex:

If a = b Then -Positive condition

If Not (a = b) Then -Negative condition
Or
If a <> b Then
--------------------
2) Compound Condition (Positive / Negative Conditions)

If a > b And a > c Then

3) Nested Condition (Positive / Negative Conditions)

If a > b Then
 If a > c Then
  If a > d Then
.
.
-----------------------------------
> Usage of Conditional statements

1) Execute a Statement when condition is True/ Simple if

Syntax:

If Condition Then Statement

Example 1:
Dim myDate
myDate = #10/10/2014#

If myDate < Date Then myDate = Date
Msgbox myDate

Example 2:
Dim myDate
myDate = #10/10/2016#

If myDate < Date Then myDate = Date
Msgbox myDate
------------------------------------------
2) Execute a block of statements when condition is True.

Syntax:

If Condition Then
Statements
-----------
---------
End If

Example:
Dim a, b
a =100
b = 50

If a > b Then
    Msgbox "A is a Big Number"
End If
-------------------------------------
3) Execute a block of statements when condition is True, otherwise execute another block of statements.

Syntax:

If Condition Then
Statements
-----------
---------
Else
Statements
---------
-----------
End If

Example:
---------
Dim a, b
a =100
b = 50

If a > b Then
    Msgbox "A is a Big Number"
    Else
    Msgbox "B is a Big Number"
End If
------------------------
Example 2:
---------------
Dim a, b
a = InputBox("Enter A Value")
b = InputBox("Enter B Value")

If Cint (a) > Cint (b) Then
    Msgbox "A is a Big Number"
    Else
    Msgbox "B is a Big Number"
End If
-----------------
Example 3:
---------------
Dim a, b
a = InputBox("Enter A Value")
b = InputBox("Enter B Value")

If IsNumeric(a) = True And IsNumeric(b) = True Then
If Cint (a) > Cint (b) Then
    Msgbox "A is a Big Number"
    Else
    Msgbox "B is a Big Number"
End If
Else
Msgbox "Invalid Input"
End If
---------------------------------
4) Decide among several alternates (Elseif Structure)

5) Execute a block of statements when more than one condition is True (Nested if)

6) Decide among several alternates (Using select case structure)
