Q. What is the Diff between Image check-point and Bit map Check point?

A.  Image checkpoints enable you to check the properties of a Web image.
You can check an area of a Web page or application as a bitmap. While
creating a test or component, you specify the area you want to check by
selecting an object. You can check an entire object or any area within an
object. QuickTest captures the specified object as a bitmap, and inserts a
checkpoint in the test or component. You can also choose to save only the
selected area of the object with your test or component in order to save disk Space
For example, suppose you have a Web site that can display a map of a city
the user specifies. The map has control keys for zooming. You can record the
new map that is displayed after one click on the control key that zooms in
the map. Using the bitmap checkpoint, you can check that the map zooms
in correctly.
You can create bitmap checkpoints for all supported testing environments
(as long as the appropriate add-ins are loaded).
Note: The results of bitmap checkpoints may be affected by factors such as
operating system, screen resolution, and color settings.
Q. How many ways we can parameterize data in QTP ?
A. There are four types of parameters:
Test, action or component parameters enable you to use values passed
from your test or component, or values from other actions in your test.

Data Table parameters enable you to create a data-driven test (or action)
that runs several times using the data you supply. In each repetition, or
iteration, QuickTest uses a different value from the Data Table.

Environment variable parameters enable you to use variable values from
other sources during the run session. These may be values you supply, or
values that QuickTest generates for you based on conditions and options
you choose.

Random number parameters enable you to insert random numbers as
values in your test or component. For example, to check how your
application handles small and large ticket orders, you can have QuickTest
generate a random number and insert it in a number of tickets edit field.
Q. How do u do batch testing in WR & is it possible to do in QTP, if so explain?
A.  Batch Testing in WR is nothing but running the whole test set by selecting "Run Testset" from
the "Execution Grid".The same is possible with QTP also. If our test cases are automated then
by selecting "Run Testset" all the test scripts can be executed. In this process the Scripts
get executed one by one by keeping all the remaining scripts in "Waiting" mode.
Q. If I give some thousand tests to execute in 2 days what do u do?
A. Adhoc testing is done. It Covers the least basic functionalities to verify that the system
is working fine.
Q.what does it mean when a check point is in red color? what do u do?
A.  A red color indicates failure. Here we analyze the the cause for failure whether it is a Script Issue or Envronment Issue or a Application issue.
