Tell me the QTP Advantages and Disadvatages ?

Answer Posted / anil ekka

Pros:
? Will be getting the initial focus on development of
all new features and supported technologies.
? Ease of use.
? Simple interface.
? Presents the test case as a business workflow to
the tester (simpler to understand).
? Uses a real programming language (Microsoft?s
VBScript) with numerous resources available.
? QuickTest Pro is significantly easier for a non-
technical person to adapt to and create working test cases,
compared to WinRunner.
? Data table integration better and easier to use
than WinRunner.
? Test Run Iterations/Data driving a test is easier
and better implement with QuickTest.
? Parameterization easier than WinRunner.
? Can enhance existing QuickTest scripts without
the ?Application Under Test? being available; by using the
ActiveScreen.
? Can create and implement the Microsoft Object Model
(Outlook objects, ADO objects, FileSystem objects, supports
DOM, WSH, etc.).
? Better object identification mechanism.
? Numerous existing functions available for
implementation ? both from within QuickTest Pro and
VBScript.
? QTP supports .NET development environment
(currently WinRunner 7.5 does not).
? XML support (currently WinRunner 7.5 does not).
? The Test Report is more robust in QuickTest
compared to WinRunner.
? Integrates with TestDirector and WinRunner (can
kick off WinRunner scripts from QuickTest).
Cons:
? Currently there are fewer resources (consultants
and expertise) available due to QTP being a newer product
on the market and because there is a greater Demand than
Supply, thus fewer employee/consulting resources.
? Must know VBScript in order to program at all.
? Must be able to program in VBScript in order to
implement the real advance testing tasks and to handle very
dynamic situations.
? Need training to implement properly.
? The Object Repository (OR) and ?testing
environment? (paths, folders, function libraries, OR) can
be difficult to understand and implement initially.
