THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
- In your existing test plan, make sure that any variations in testing make use of variables. For example, if running a HTTP sampler, use HTTP Request Defaults to specify a host as "
${+P(targetHost)
}". Other useful places for variables might include number of threads, ramp-up period or scheduler duration in a thread group, using a format of${+P(threadgroup.threads,500)
} (The+P
function is shorthand for+parameter
. See the userguide for more info on using this parameter). - Save your test plan and properties file to a directory.
- Create a properties file containing all your variables. E.g. mytest.properties could contain threadgroup.threads=100, targetHost=my-target-host.com
- The test plan does not need Listeners, as this will be configured via parameters. This will improve performance on the testing.
- Run the test mode in stand-alone mode (i.e. no remote servers):
jmeter -n -t load_test.jmx -l load_test_report.jtl -q mytest.properties -j mytest.log
- 1 small piece of functionality missing is the ability to set global variables from a property file. the "-q" parameter defines an additional property file, which is the equivalent of setting properties for the contents of the file using the -J parameter. This These parameters are not global however, as would be set by the -G parameter. the following bash script (if your using Linux) would help with converting a properties file to global properties:

for var in `grep -vE "^(#|$)" mytest.properties`; do
GLOBAL_VARS="-G${var} ${GLOBAL_VARS}"
done
|
...
- The -G parameter can reference either a property in the format of
-Gprop=val
or a properties file, such as-G./myglobal.properties
- On all client machines, start up JMeter server, ensuring that firewall is not blocking connections (clients must all be on the same subnet).
- On JMeter controller (the host initializing the test), run the test with the -R parameter (can be run using -r and specfiying hosts in jmeter properties file):
jmeter -n -t load_test.jmx -l load_test_report.jtl -q mytestGmytest.properties -j mytest.log -R remotehost1,remotehost2 ${GLOBAL_VARS
}
