Per VU Iterations

Set iterations

Select Per VU Iterations from the dropdown menu, and set the number of virtual users, iterations, and the maximum test duration.

• Virtual users: Enter the total number of users to simulate during the test.
• Iterations per VU: Specify the times each virtual user runs the script.
• Max duration: Specify the upper bound on the test runtime (in minutes).

Hybrid tests

For iterations with hybrid load tests:

• Set iterations separately for browser and API load. You can pass any value between 1 to 100000.
• If you also set a maximum duration, the hybrid test stops when either the configured iterations or the maximum duration is reached, whichever comes first.

Set iterations

Use iterations to control how many times each virtual user (VU) executes your test script:

• Set iterations to a positive integer. You can pass any value between 1 to 100000.
• Combine with duration if needed. When both are set, the test stops when either the max duration or the iterations are reached, whichever comes first.

vus: 5
duration: 5m
#per VU iteration
iterations: 20

Hybrid tests

For hybrid load tests (browser + API):

• You can set iterations at the global level (outside the tests block) or at the test-level (inside the tests block) or at both levels.
• If set at the global level, then this value applies to both browser and API tests that you configure in the tests block.
• You can also optionally add iterations for a specific test inside the tests block. The test-level value takes precedence over the global value for that test.
• At the global level, you must set at least one of duration or iterations. When both duration and any iterations limit are configured, the hybrid test stops as soon as one of those limits is reached.

Example hybrid configuration:

vus: 10
duration: 10m
iterations: 50        # 50 iterations for all VUs for both browser and API tests
tests:
    - testType: Selenium
      browserLoadPercent: 10
      iterations: 20  # 20 iterations for browser tests, global-level iterations are overridden
    - testType: k6    # 50 iterations for API tests, global-level iterations are honoured
      apiLoadPercent: 90
