Usually, the test cases you work on wouldn’t have a straight linear flow. You would normally come across many conditions in your test case flow and based on the results of these conditions you would be required to perform different actions. In VBScript this can be achieved using the following 2 conditional statements –

• # If…Then…Else statement
• # Select Case statement

Let’s see how to use these conditional statements in our scripts.

If… Then… Else statement

The If Then Else statement evaluates whether a condition is true or false, and then based upon the result certain set of statements are run. Let’s see a basic example for this.

dtSomeDate = #01/01/2012#

'Check if the given date was in the past
If dtSomeDate < Now Then
  msgbox "The given date is in past"
End If

In the above example, only one condition was checked in the If statement. If you want, you can check multiple conditions using multiple ElseIf statements. Let’s see an example for this.

'Code to check multiple conditions using Else If statement

Dim sMonth

'Find the month from today's date
sMonth = Month(Now)

If sMonth = 1 Then
  msgbox "Month is January"
ElseIf sMonth = 2 Then
  msgbox "Month is February"
ElseIf sMonth = 3 Then
  msgbox "Month is March"
  '..... so on ....
End If

You can check multiple conditions within a single If statement using And & Or operators.

'Find if a given number is given number if even and is less than 100

Dim iNum
iNum = 50

If (iNum mod 2 = 0) and (iNum < 100) Then
  msgbox iNum & " is a even number less than 100"
End If

Nested If Statements Nested If statement is where you can have an If statement within an If statement.

'Find if a given number is given number if even and is less than 100

Dim iNum
iNum = 50

If iNum mod 2 = 0 Then
  'Check If number is less than 100 or not
  If iNum < 100 Then
    msgbox iNum & " is an even number less than 100"
  Else
    msgbox iNum & " is an even number greater than 100"
  End If
Else
  msgbox iNum & " is an odd number"
End If

Select Case statement

Select Case statement works on a single expression which is evaluated at the beginning on the Select Case statement. The result of the expression is then compared with the values for each Case in the structure. Select Case statement is similar to If Then Else but it makes the code more readable. Let’s see an example of Select Case statement.

Dim iWeek

iWeek= 3

Select Case iWeek
  Case 1
    msgbox "Today is Sunday"
  Case 2
    msgbox "Today is Monday"
  Case 3
    msgbox "Today is Teusday"
  Case 4
    msgbox "Today is Wednesday"
  Case 5
    msgbox "Today is Thursday"
  Case 6
    msgbox "Today is Friday"
  Case 7
    msgbox "Today is Saturday"
  Case Else
    msgbox "Invalid Number"
End Select

Similar to nested if statements, you can also have nested select case statement. You can also create select case within an if statement and vice-verse.
