Subject Re: Jmeter Hangs - Running 150 HTTP Requests
Date Thu, 16 Mar 2017 10:58:04 GMT
Hi Felix,

- Yes I have large responses.

- Regarding your first option, if I disable the result tree element while
running, how will be I able to see the results for debugging. When I record
a script, I need to execute it once to see the response and get regular
expression.
I tried running in Non-GUI mode but after that I am not able to see the
request in view result tree. Posted other mail in group with subject
"Jmeter in Non-GUI Mode - Blank Request and Response".

- Regarding second option, I downloaded latest files from "
https://ci.apache.org/projects/jmeter/nightlies/", this version also hangs
when I execute whole flow and try to click on requests to see the result.

*Files downloaded:*
apache-jmeter-r1787116
apache-jmeter-r1787116_src

Not able to find help for "Run ant download_jars from the top-level
directory to fetch the dependencies." mentioned on above site.

In addition, I am trying to run jmeter from ant and getting below error,
reference (
http://testingfreak.com/step-by-step-process-to-run-jmx-file-through-command-prompt-using-ant-and-generate-html-report/
)

*Changes in Build.xml (highlighted in yellow):*

-Djmeter.home=.. - C:\apache-jmeter-r1787116

        -Dreport.title="My Report" - title for html report (default is
'Load Test Results')

    </description>



    <property name="testpath" value="${user.dir}"/>

    <property name="jmeter.home" value="C:\apache-jmeter-r1787116"/>
