JMeter : Some Questions

[Umesh Kulkarni <Um...@oracle.com>]

Hello All,

I have following questions regarding JMeter.

a) How can we typically model a Web Application say a JSP, a Servlet, a
JSP-EJB application as a test plan ?
(Does this simply involves specifying FORM parameter names,values and
URL or anything else is also involved )

b) Can we measure the performance of the whole application or the
performance of only rendering the first (front) page of the application
is possible through JMeter ?

c) Is it possible to capture the actions which user has entered and
replay them using JMeter ? How ? What is the xml file created to record
user events.

Your help in this regards is highly appreciated.

Thanks
Regards

If your application is browsed by a browser, JMeter can simulate it.  You 
need to know the HTTP requests that your browser generates, and yes, that's 
mostly URL's and form parameters.  JMeter doesn't test javascript currently, 
though.

Images, CSS stylesheets, etc aren't automatically located and downloaded by 
JMeter.  I believe there is someone working on it (well, maybe that's you - I 
don't keep track of all the names too well!).  However, for most 
applications, the performance of image downloading would not be the crucial 
factor.  In any case, I don't think JMeter is an ideal tool for test 
bandwidth.  It is better for testing a highly dynamic and CPU intensive web 
application.

Yes, but it's currently only in CVS code, and it's undocumented.  I will try 
to change that shortly, and I'll notify the lists.
