Read( ),Readline( ),ReadAll( ) methods with syntax's
QTP ReadLine(), ReadAll(), Read() SYNTAX
Readline ( ):-
We can use this method to read current line from file and move control to next line.
Syntax:- fo.readline( )
Readall( ):-
We can use this method to read all lines in the file at a time.
Syntax:- fo.readall( )
Read( ):-
We can use this method to read specify no:of characters from current line.
Ex:- My name is khan
---------
---------
X=read(4)
Print(x) o/p: My n
Regular expression & methods with Examples
Regexp object:-
Regexp object is used to integrate QTP with regular expression utilization. This object consist of 3 properties and 3 methods
A) Pattern:- we can use this property to store expected expression for matching.
Syntax:- set r=new regexp
r.pattern=”regexp”
r.global=true/false
B) Global:-
We can use this property to specify pattern matching on given text until end of text.
Syntax:- set r=new regexp
r.pattern=”regexp”
r.global=true/false
c) Ignorecase:-
We can use this property to specify case sensitiveness.
Syntax:- set r=new regexp
r.pattern=”[A-Z][a-z]+”
r.global=true
r.ignorecase=true
In example code, a string will be matched with pattern which start’s with lowercase also. Because ignorecase is true.
D) Execute( ):-
We can use this method to apply given pattern on given text and find matched values in text.
Ex:- set r=new regexp
r.pattern=”[0-9]+”
r.global=true
x=”jky345 acd 23 jkil34dd”
set y=r.execute(x)
for each z in y
print(z.value)
next
E)Test:-
We can use this to apply given pattern on given text for matching. If pattern was matched with matched with text , then this method returns true.
Ex:- set r=new regexp
r.pattern=”[0-9]+”
r.global=true
x=”544755”
if r.test(x) then
print(“matched”)
else
print(“mismatched”)
end if
A) Replace( ):-
We can use this method to replace matched text with other text.
Ex:- set r=new regexp
r.pattern=”[0-9]+”
r.global=true
x=”my name is 5”
r.replace(x,”A”)
print(x)

Working with Text Files/Flat Files/Sequenctial Files & Examples
Working with text files:-

Syntax:- option explicit
Dim fso,fo
Set fso=createobject(“scripting.filesystemobject”)
Set fo=fso.opentextfile(“path of file”,1/2/8,true/false)
True=file was create, while file was not found, 1=read mode
False=file not create, while file was not found 2=write mode
8=append mode
EX:-1

File name:- sample.txt
1.my name is kishore
2.hello
3. how are you?
Option explicit
Dim fso,fo,l
Set fso=createobject(“scripting.filesystemobject”)
Set fo=fso.opentextfile(“c:\sample.txt”)
While fo.atendofstream< >true

print(l)
wend
fo.close
set fo=nothing
set fso=nothing
EX:-2

Dictionary objects methods "Add()","Item()","Keys()","Items()","key",Remove()","RemoveAll()","Exist()" & Examples
Add( ):-
We can use this method ,to “Add” a pair to dictionary.

Key:-
We can use this property to change existing key to new key.
EX:- set d=createobject(“scripting.dictionary”)
d.add “math”,124
--------------------
--------------------
--------------------
d.key(“math”)=”mathes”
--------------------
--------------------
Remove( ):-
We can use this method to remove specified pair from dictionary.
EX:- set d=createobject(“scripting.dictionary”)
d.add “maths”,123
d.add “physics”,232
------------------
------------------
d.remove(“maths”)
Removeall( ):-
We can use this method to remove all pair in dictionary.
EX:- set d=createobject(“scripting.dictionary”)
d.add “maths”,123
d.add “physics”,89
d.add “social”,322
-------------------
-------------------
d.removeall
Exist( ):-
We can use this method to verify the existence of specified pair in dictionary.
Ex:- set d=createobject(“scripting.dictionary”)
D.add “maths”,322
d.add “physics”,89
------------------
------------------
If d.exist(“maths”) then
Print(“maths available”)
End if
Note:-
The data structures like variables ,arrays ,and dictionary are temporary ,because they are creating in ram. Due to this reason testers are using files, because files are saving in hard disk.
