A checkpoint verifies that expected information is 
displayed in a Application while the test is running. You 
can add eight types of checkpoints to your test for 
standard web objects using QTP.
?A page checkpoint checks the characteristics of a 
Application
?A text checkpoint checks that a text string is displayed 
in the appropriate place on a Application. 
?An object checkpoint (Standard) checks the values of an 
object on a Application. 
?An image checkpoint checks the values of an image on a 
Application. 
?A table checkpoint checks information within a table on a 
Application
?An Accessiblity checkpoint checks the web page for Section 
508 compliance. 
?An XML checkpoint checks the contents of individual XML 
data files or XML documents that are part of your Web 
application.
?A database checkpoint checks the contents of databases 
accessed by your web site

check points are used for checking the conditions within 
the script..

check points are similar to the conditional statements(like 
If, if else,for, while etc)

we can have one or more check points for an object or 
multiple objects with in a test.

Results in the results page are updated based on the check 
points.
 
QTP supports 7 types of check points

1.Standard Check point

2.Text Check point

3.Text Area Check point

4.Bit Map Check point

5.Accessibility Check Point

6.Data Base Check point

7.XML Check Point

Additional Check points for Web application

8.Image Check Point

9.Page Checck point

When we execute a script with check points, if the check 
point fails then the expected value along with the actual 
value is captured with the image of that object.

having many check points in a script will reduce the speed 
of execution.

a checkpoints is a specialized step that two values and
reports the result.
checkpoint compare the actual result value from the test run
run with the expected result in a test plan .

the expected result are based on what is recorded .and the
actual result are based on what occur during a test run.
if two values match the checkpoints pass otherwise
checkpoints fail .there r 9 type of checkpoints in qtp.

A Check point is used to compare our Expected value with our
build Actual Value. There are 8 types of Check points in QTP.

1. Standard Check Point
2. Bitmap Check Point
3. Database Check Point
4. Text Check Point
5. Text Area Check Point
6. Accessibility Check Point
7. XML Check Point - Web page
8. XML Check Point - File
