Stepping Thread Group

What it is

The Stepping Thread Group lets us:

• Determine the same parameters as the standard Thread Group
• Increase thread load by portions
• Configure hold target load time
• Decrease load by portions.

Example

scenario:

• 1,000 threads as target load
• 0 seconds waiting after the test starts
• 0 threads run at the immediate beginning of the test
• 100 threads are added every 30 seconds with a ramp-up (or step transition time) of 10 seconds
• The target load is held for 300 seconds (5 minutes)
• Finally, 10 threads are stopped every 3 seconds.

This means that:

• The test begins immediately when JMeter starts, since there is 0 seconds waiting.
• Every 30 seconds 100 users will be added, until we reach 1,000 users. The first step is 1-100, the second 101-200, etc., because we defined 0 threads to run at the beginning. If we defined 50 threads to run the first step would be 51 - 150, the second 151 - 250, etc. and the test would be completed faster.
• It will take each of the steps (with 100 users each) 10 seconds to complete. After that JMeter waits 30 seconds before starting the next step.
• After reaching 1,000 threads all of them will continue running and hitting the server together for 5 minutes.
• At the end, 10 threads will stop every 3 seconds.
