empty props in another threadgroup

[L König]

Hey,

We're trying to test one of our APIs. The test is divided into two thread groups. In the first, auth-tokens are written to the properties (props.put) in a list.

In the second thread group, one of these tokens should be read from the list (props.get) in order to call our API. The list or property in the second thread group can

no longer be read and returns an IndexOutOfBoundsException. Unfortunately, the Blazemeter support couldn't help me.

I am thankful for all help

We neither can provide "all" help nor "any help" without seeing your code. Given it doesn't have any errors (check jmeter.log file) passing the properties across Thread Groups should work just fine. Just make sure that your first thread group is really gets executed first, i.e. "Run Thread Groups consecutively" box is checked in Test Plan level.

You can also consider using Inter-Thread Communication Plugin  for passing the data across Thread Groups.

The shortened jmeter-file is attached and the option "Run Thread Groups consecutively" is already active

From the first glance it should work.

Here is a very minimal testplan demonstrating the concept.

I would recommend checking the values of your sessionId and allSessions variable and property using Debug Sampler and View Results Tree listener combination in the "Create global parameters" Thread Group

Again check jmeter.log file for any suspicious entries.
