Hi Everyone:
The upside of JMeter's protocol-focused testing is tremendous scale.
One can run thousands of test cases concurrently in a computer of
modest proportions.
The downside of this approach is that protocol-level testing is much
more difficult to apply to Web applications that maintain stateful
operations in the client. Many new systems I work with have data
persistence, event mechanisms, server daemon-based logic, custom
business logic, and desktop integration in a client running in the
browser. Emulating all of this in a protocol driven test is very
difficult.
At PushToTest we implemented a test architecture using the Htmlunit
headless browser framework. Htmlunit runs the client, including
Javascript from an Ajax application, just as Firefox or Internet
Explorer does. We can easily instantiate hundreds of Htmlunit
instances in the memory of a test running machine. The downside to
this approach is the need for more load test running boxes to achieve
your virtual user counts because of the significant extra overhead.
There is a good alternative now available from PushToTest. TestMaker
now runs JMeter tests. This enables you to combine protocol driven
tests with SeleniumHtmlunit tests in one test use case. For example, a
test use case composed of multiple test steps runs a JMeter test, then
shares the set cookies and other values with a Selenium tests.
I would be happy to organize a live group Webinar-style meeting to
show off the new integration and discuss enhancements. Please let me
know your thoughts. Thanks.

Hi
well not exactly.
An AJAX request is in the end an http request/response so yes JMeter
can do
that, and you can perform basic functional and performance tests.
However Jmeter is not a browser and doesnt execute javascript and wont
behave like it , so some of the things that people would like to do
(e.g. an
AJAX system that polls or responds to a user doing something like
type half
a word in a textbox ) cant be directly mapped to JMeter , though
you'd
probably have workarounds. JMeter also doesnt do well(but can still
work)
with dynamic systems like GWT whose outputted Javascript is a whole
bunch of
gibberish that needs to be carefully extracted and worked with.
JMeter /
Load Runner should have similar limits , the difference being that
Jmeter
makes its far easier than Load runner to perform the same task. If
you can
elaborate the problems you ran into with LoadRunner we could see if
Jmeter
can deal with the same issue.
If your focus is a functional test then testing systems which drive
the
browser Selenium/Watir/QTP are better options , imo , than JMeter.

Hi Deepak,
Okay. To give you a better idea is I want to take a web app that
uses the
browser and execute a test case and then after is done rerun the
test case
through JMeter. The web app uses AJAX for parts of it.
We use LoadRunner right now but we see/test so many different apps
and
LoadRunner has limits for testing web pages that use AJAX. So need
more info
about JMeter.
Does that help?
Thanks,
-Tony

Yes but your mileage varies based on your expectations on the
meaning of
"test AJAX".

Hi All,
Is it possible to use jmeter to test AJAX based web pages? If so
is it
AJAX
vendor version specific?
Thanks,
