The feature works out of the box. automatically detects previous test runs in report folder and uses them for comparison.

See an example report here

trend-analysis-load-test-report-smartmeter-io-tableThe table contains following metrics:

  • The maximum number of reached virtual users

  • Test duration

  • Average reponse time

  • Total errors

  • Total hits

  • Hits per second

Comparison charts


For each transaction in test scenario there is a comparison chart for following metrics:

  • Average Response Times

  • Median Response Times

  • Error Rate


Test runs are grouped by test script name (.jmx file). In case of major changes in the test script we recommend to version its name to start over.

If you want to exclude a test run from comparison, either remove the whole report folder or delete the data/test-summary.json file from it. Then generate the last report again.
