Utilization

The utilization section of the triage report assists in optimizing your Antithesis usage. You might wonder: should you run your existing tests with more parallelism? Or, should you instead strengthen your testing by improving the test template or by adding sometimes assertions? This section helps answer that question by graphing the number of new behaviors discovered over time.

If the graph is still increasing at the end of your run, this indicates that you have not yet hit diminishing returns on your existing tests, and would benefit from running with more parallelism. Conversely, the graph becoming entirely horizontal indicates that longer testing is unlikely to provide additional value. In this case, you should try to strengthen your testing instead.

It is normal for autonomous testing to discover a great deal of new behavior early and for this to plateau as low-hanging fruit is picked. Thus the graph will generally flatten out even for valuable tests – however, it should not hit an asymptote.
