QTP is a Functional regression testing tool where as
LoadRunner is a Performance testing tool.
You can use both tools for ERP as
well as Web based applications .Bcoz both of them supports
ERP applications and web applications.
But with the QTP you can do only regression testing . that
means the functionality of an application with respect to
new builds/versions as well as integration testing.
With QTP
ex.for ERP application
You can check whether were you able to select different
menus, menu items ,buttons,links etc.and were you able
perform different functionalities of application.ex.
calculating bonus etc on payroll .
ex. for web application
you can check the functionality of the application isworking
as expected.
example
if you give correct username and password and you clicked
sign in button .so you can check whether the sign in button
is enabled and take you to the correct page after clicking
the button.
where as with the LoadRunner you can see the Performance of
an Application with respect to max of loads simultaneously
at peak usage of an application.that means stability of an
application at peak usage .
with LoadRunner
1.ex.for ERP
You can see the performance of ERP application while
processing 1000's of Employees payslips .you can see the
application server response time etc
2.ex.for Web application
You can see the applications stability w.r.p. 1000 login's
at the same time.that means you are measuring the
application server's response time to load a page with
respect client's request . ex. Yahoo login page.
