Dynamic Adjustable Curve Stress Tests allow users to change the load manually during the test runtime.
How it works
The test starts with the specified number of concurrent users. During the test execution, you can change the user load in live mode. You can also manually adjust the load distribution between LIs zones. The test report charts update as you adjust the load, giving you a visual representation of the test results in real-time.
Configuring a Dynamic Adjustable Curve
To configure the initial settings for Dynamic Adjustable Curve, you need to set up initial test settings:
- the starting number of concurrent users to load the site with in the Start Users box
- the maximum number of users at a moment in the Max Users box
- the maximum test duration (in minutes) in the Max Duration box.
On the Stress Test Report page, the curve of the actual number of virtual users in use appears on the Execution Plan chart.
In the Dynamic Adjustable Curve section, you can see the following test parameters:
- Current Load – the actual users number simulated currently.
- Target Load – the target number of users (may differ from Current Load, since LIs need some time to simulate the necessary number of users).
- Capacity – the maximum available number of concurrent users.
To change the load, simply move the Total Load by Zones slider to a target position in the Dynamic Adjustable Curve section.
To adjust the load at each zone separately, expand the Total Load by Zones header and move a slider related to a necessary zone.
When the test finished, you can also review the test results on the Stress Test Report page.
