Problem:

I am currently hard coding a password in my jmeter .jmx test file. I want to be able to either set this in the config.yaml or on the command line using something like a "-o modules.jmeter.properties" switch (to replace this in the CI pipeline)

However I cant get either of these to actually replace the value in the .jmx file.

I have looked through the Taurus doco and ended up trying the following.

Updating the config.yaml file:

execution:
- executor: jmeter
  scenario:
   script: ../scripts/apigee_loadtesting.jmx
   data-sources:
    - ../datafiles/
 concurrency: 2
 ramp-up: 30s
 hold-for: 1m
 steps: 2

modules:
  jmeter:
    properties:
      es.password: P@ssw0rd!

Also tried this from the commandline:

bzt ../config.yaml -o modules.jmeter.path=/usr/local/apache-jmeter-4.0.2/bin/jmeter \
-o modules.jmeter.properties.espassword=P@ssw0rd! config.yaml

But neither of them seem to do anything meaning, Any suggestions would be appreciated

  1. Taurus itself will not change anything in the .jmx script, just make sure that you refer the property using __P() function as ${__P(es.password,)} in the .jmx script and the value will be substituted with the one from .jmx file or command-line override.
  2. I would avoid using dots in properties names as it might cause problems with overriding properties values from the command-line. So stick to espassword everywhere if possible

  3. The change your command line so config.yaml would be the last argument like:

    bzt -o modules.jmeter.path=/usr/local/apache-jmeter-4.0.2/bin/jmeter -o modules.jmeter.properties.espassword=P@ssw0rd! config.yaml

  • That seems to have done the trick. I can pass it in from the commandline. i do a similar thing with the thread, steps etc. Couldnt get it to work for this previously. Cheers for the help – Scotty G Sep 04 '18 at 10:37
  • I'm running a performance test jenkins job configured using taurus. I have existing jmeter jmx file which i would like to run with this job. This jmx file is expected to read inputs from jenkins job inputs. So, i configured jmx file as said by @Dmitri T with $_P() for reading inputs, but still the values coming as empty during test run. Any help would be very much appreciated. – naresh goty Aug 06 '19 at 22:54
