correct me as i'm probably wrong, but a setUp thread cannot be used to store variables for use on the test threads (that i can see). any variables that i use in the setUp are never available. however, i found that if i use a beanshell and convert the variable in the setUp thread to a property like this ${__setProperty(userToken, ${userToken})};

then on each test thread i either use the property directly like:

${__property(userToken)}

or at the top of my thread i convert the property back into a variable like: vars.put("userToken","${__property(userToken)}")

however, this seems a bit long winded and it would be great if there was a way to set up variables in the setUP to be used on every thread.

A special type of ThreadGroup that can be utilized to perform Pre-Test/ Post-Test Actions.The behavior of these threads is exactly like a normal Thread Group element. The difference is that these type of threads execute before/after the test has finished executing its regular Thread Groups.enter image description here

It sounds like you have pretty much figured it out already, but let me give you a few examples of when I've used it.

setup:

  • Get a large data set from a database into a jmeter variable for use during the test.
  • Get and log the version number from the system under test:s version number.
  • Run a javascript to set jmeter properties based on more simple input parameters/properties. Lets say you want to configure the selection of target host a simple true/false value, but in your test you need to expand it to different strings, and you dont want to have logic spread out all over your test plan.

teardown:

  • Never used it, but I guess it is mainly useful for cleaning up your system (e.g. deleting users that were created during the test)
