Adding custom counters to reports

Starting from V10.1.0, you can view and monitor the counter information generated by the custom code on a graph when the custom code starts in the test run.

After running tests, you can view the custom counter in the report. You can also view the custom counter information on a different page by creating a custom report. For more information about customizing the report, see related links.

You can add the following custom code in your test to create a custom counter in a report.
