Explain typename function in QTP.

Typename function is useful when you want to know the data type of the variable.

Vb script is a scripting language used in QTP. All variables used in QTP are by default variant.
When we assign a value to variable, its data type changes.

For example -
print typename(a)  'Empty

a=10
print typename(a)  ' Integer

a=10.2
print typename(a) 'Double

a="sagar"
print typename(a)  'String

a=null
print typename(a) 'Null

This is how we can use the typename function in QTP to find the current data type of the variable.

Explain Ubound function in QTP.

Ubound stands for upper bound. This functions is used to find the upper bound of the array.

Syntax -

ubound(arrayname, dimension)

It returns the upper bound of the arrayname and dimension used is specified in second parameter.
By default dimension is 1.

Example -

Single dimension array

Dim a(2)
'Declare an array with upper bound (index) as 2.

a(0) = 0
a(1) = 0
a(2) = 0

print ubound (a)           'will print 2
print ubound (a,1)        'will print 2

'This will print the value 2 as upper bound of the array is 2.

Please note that size or length of the single dimension array is ubound + 1.

Multi dimension array

Dim b(2,3,5)

print UBound(b, 1)           ' will print 2

print UBound(b, 2)           '  will print 3

print UBound(b, 3)           '  will print 5

How to find the name of the week day for given date in QTP?

You can find the name of the weekday like sunday, monday etc from a given date using below code.

There are 2 functions which help you find the name of week day or weekday name.

1. Weekday(anyvalid_date)  -  returns the numeric representation of weekday.
2. Weekdayname(intX)         - returns human readable weekday name like monday, sunday etc

print weekdayname(weekday(now))

Above statement will print the today's day name.

print weekdayname(weekday("09-jan-1986"))
'Will print thursday

To get the day name in abbreviated form use below statement
print weekdayname(weekday("09-jan-1986"), true)
'Will print thu.
Thus when you pass the second parameter as true, you will get the name in 3 letter format like sun, mon etc.

Above statement will print the name of day on 09-jan-1986.

Numeric representation of weekday is given below


1 - Sunday (default)
2  - Monday
3  - Tuesday
4  - Wednesday
5  - Thursday
6  - Friday
7  - Saturday

You can also use above statement to find out the day on which you were born.

Example to find the date of birth weekday -

Assume that your birthday is 24-oct-1985

dob = #24-oct-1985#
print weekdayname(weekday(dob))

This is how you can find the name of the weekday in QTP and vbscript.

How to get the current year in QTP?

There are many scenarios where you will need to find the current year in QTP.

Example -

Consider a scenario where you have to verify that the year displayed on the web page is correct or not.
Please note that You have to just verify the year in yyyy in this format and not the entire date.

QTP (Vb script) provides below function to find the current year.

print year(now)  

Above statement will print the current year.

The only parameter year function takes is the valid date. So if you want to find the year part of any given date in QTP you can pass the date as a first parameter.

Example -

print year("3-jun-2011") 

Above statement will print 2011.

Real Life usage of Year function in QTP. (Practical Project application of Year function)

We can use year function to find the current date which can be used to create unique random numbers. Random numbers or strings can be used in many situations like creating automation reports with unique file names.

This is how you can get the year of any given date in vbscript and QTP.

What is the difference between Round, Int and Fix in QTP ?

To know what round function is used for in QTP click this link Round function

Difference between int and fix 

Case 1  - Positive numbers

Int and fix function return the integer part of positive number.
For example -
print int(77.4)     ' Will print 77
print fix(77.4)     ' Will print 77
So when the numbers are positive, both the functions int and fix behave in same manner.

Case 2  - Negative numbers

print int(-77.4)     ' Will print -78   (return value is less than or equal to number)
print fix(-77.4)     ' Will print -77   (return value is more than or equal to number)

Basically for positive numbers, int and fix return same value for a given number.
For negative numbers above logic applies.

What is Round function in QTP?

QTP supports round function that can be used to round the decimal numbers.

For example -

mydecimal = 6.34344 

roundedvalue= Round(mydecimal , 3)
print roundedvalue ' it will print 6.343

The second parameter to round function determines how many places to the right of the decimal should be used.

Another example of rounding.

mydecimal = 6.34644 

roundedvalue= Round(mydecimal , 2)
print roundedvalue 

' it will print 6.35 because the third decimal place value (6)  is greater than or equal to 5.

How to generate the random number in QTP ?

QTP supports the function called Rnd that generates random value between 0 and 1.

rnd function takes 1 input parameter which acts as a seed to generated further random numbers in sequence.

To initialize the seed with system timer, you can use below statement.

Randomize


To generate the random integers we can use below statement.

Method 1
min = 1
max = 100

Randomize
RandomInt1= (Int((max-min+1)*Rnd+min))
RandomInt2= (Int((max-min+1)*Rnd+min))

print RandomInt1  'print the first random integer between 1 and 100.
print RandomInt2  ' print the second  random integer between 1 and 100.


Method 2

x=RandomNumber (0,100)

print x

This is how we can generate random numbers in QTP.

How to create a array of dictionary in QTP?

In QTP and vbscript we can create array of dictionary using below syntax/ example.


dim ArrayofDictionary(2)


'Now let us make first element of array as dictionary

Set ArrayofDictionary(0)= createobject("scripting.dictionary")
ArrayofDictionary(0).Add "key1", "temp1"
ArrayofDictionary(0).Add "key2", "temp2"

'Added keys in first dictionary


'Now let us make second element of array as dictionary

Set ArrayofDictionary(1)= createobject("scripting.dictionary")
ArrayofDictionary(1).Add "key1", "temp1"
ArrayofDictionary(1).Add "key2", "temp2"

'Added keys in second dictionary

and so on ............

To access the values inside dictionary, use below syntax.

print ArrayofDictionary(1)("key2")

This is how we can create an array of dictionary to store dictionaries in each element of Array.

Difference between dictionary and array in QTP

Here is the difference between Array and dictionary in QTP.
Below comparison illustrates when we should use array and dictionary.

	Array	Dictionary
1	We can have dynamic array	We do not have concept called dynamic Dictionary.
2	Before use of array we must set the size of array	We do not need to set the size of dictionary.
3	Before adding extra element into dynamic array, We have to use redim  statement	We do not need to write any statement to add extra element. We just use add method.
4	We do not have any method to release the memory if particular element is not required	We can remove the element that is not required any longer.

Dictionary object has many in built functions that help us add, remove, access the elements by unique key. That is why we must use dictionary over array.

Please note that array does not have any methods to add/remove the elements.

Same comparison applies for QTP scripting and VB scripting.

How to create dynamic 2 dimensional array in QTP?

In QTP we can create dynamic array with any dimension.

Syntax -  To declare dynamic array is given below.

Dim a()

As shown above, we do not specify any dimension of array. 

To define the size of array we have to use below statement.

ReDim a(6,6)

In above statement, we have set the size of 2 dimensional array.

To preserve the existing data in array you must use below syntax.

ReDim preserve a(6,6)

Example to demonstrate 2 dimensional dynamic array is given below.

Dim a()

ReDim preserve a(6,6)

a(5,5) = array(12,33,454)

a(0,0) = array(2,3,4)

a(3,2) = 333

print a(5,5)(0)        ' prints 12

print a(3,2)        ' prints 333
