Test duration is the total time your test scenario is running on test runners. This does not include any start up, provisioning, or post-test processing time. For performance testing plans, the minimum duration is 15 minutes and after that it is rounded to the nearest minute. Also note that for some scenario types there is a multiplier (1 Playwright or Puppeteer VU = 5 billed VUs, 1 Selenium VU = 10 billed VUs). VUHs = VUs * test duration * scenario type multiplier. For example 10 JMeter VUs for 30 minutes is 5 VUH (10 VUs * 0.5 hours = 5 VUH). A 1 Playwright VU test for 10 minutes is 1.25 VUH (1 VU * 0.25 hours * 5 Playwright multiplier). Note that for browser testing plans and monitor runs the minimum duration is 5 minutes.
