JMeter share setUp Thread Group variables with normal Thread Group

Question

Imagine I have a simple test plan, like so:

setUp Thread Group
-- Http Request
---- JSON Extractor

Thread Group
-- Http Request

tearDown Thread Group
-- Http Request

By default, the variables extracted in the setUp Thread Group will not be accessible within the ordinary Thread Group nor the tearDown Thread Group . The variables' contents are different for each user and cannot be precomputed and loaded into the test plan. It is not possible to simulate the correct load using a single user.

How can I access each thread's setUp variables from within the corresponding Thread Group proper and tearDown?

Answer 1

JMeter Variables scope is limited to current Thread Group only, if you need to pass some data between different Thread Groups you need to convert JMeter Variables into JMeter Properties:

• use __setProperty() function to set a JMeter Property in ie setUp Thread Group
• use __P() function or __property() function to read the property value in another Thread Group.

5000 distributed threads.. transferring multiple variables...

Maybe JDBC Request s will help you to save(insert) variable to database and get(select) variable and delete/update variable wherever you are in test.
