Once you have modelled your stress tests with JMeter (that's another story that deserves its own post), maybe you want to launch them in a non-interactive way from your continuous integration server.
For doing so, you just need to launch JMeter with the non-interactive mode:
./apache-jmeter-2.6/bin/jmeter.sh -t my-test-plan.jmx -l my-test-plan-2012-16-09.jtl -n
This commands launch the test plans, but the output file is XML. How could I send this as a report to the QA team or the management people?
xsltproc ./apache-jmeter-2.6/extras/jmeter-results-report_21.xsl my-test-plan-2012-16-09.jtl > report-2012-16-09.html
The result will be an HTML file which is rendered as the image attached.
