JMeter recording

Hello All,

I'm JMeter beginner level user, have few questions please help:

1. Recorded sessions capturing lot of samplers though I had excluded
suggested excludes, how would I determine what samples I could delete to
determine correct response time.

2. How to debug reg. expression extractor variable value in responses
(apart from regexp tester in tree view)

3.My web-based app produce lot of run time values, I tried to correlate few
however those not done n has response assertion are passing too in tree
view..is it right results?

4.Max n min response time shown in summary report is same as webpage
loading time on browser? ( I know JavaScript isn't included in response
time)...

Thanking you all.

Regards
Srikanth

Re: JMeter recording

 1. You don't need to record any calls to images, scripts, styles, fonts,
etc. you should configure JMeter to retrieve all embedded resources from the
page and use concurrent thread pool of 4-6 threads for fetching them as this
is something what real browsers do in the  HTTP Request Defaults
<http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request_Defaults> 
.  You should also exclude requests which belong to external domains so your
test would focus only application under test and not include any stuff from
i.e. Google, Youtube, whatever. See  Web Testing with JMeter: How To
Properly Handle Embedded Resources in HTML Responses
<https://www.blazemeter.com/blog/web-testing-jmeter-how-properly-handle-embedded-resources-html-responses>  
for more details.

 2. You can use  Debug Sampler
<http://jmeter.apache.org/usermanual/component_reference.html#Debug_Sampler>  
or  Debug PostProcessor
<http://jmeter.apache.org/usermanual/component_reference.html#Debug_PostProcessor> 
. You can also print variables values to /jmeter.log/ file using  __logn()
function <https://jmeter.apache.org/usermanual/functions.html#__logn>  

 3. The question is not clear. 
 4. Well-behaved JMeter test (assumes you handle embedded resources like
described in point 1, use  HTTP Cache Manager
<http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Cache_Manager>  
to represent browser cache, use  Parallel Controller
<https://github.com/Blazemeter/jmeter-bzm-plugins/blob/master/parallel/Parallel.md#parallel-controller>  
to represent JavaScript calls, etc) should produce the same response time as
real browser does.
