Gatling is another newer player in the automated performance testing space. It is similar to Locust and is much lighter weight than the older options such as JMeter and Grinder. Built on Scala, the DSL provides extensive functionality out of the box including easily configured data feeds and response assertions. In cases where customization is needed, it is easy to drop into Scala to provide extensions. The default generation of numerous dynamic views of the data via Highcharts adds to its appeal.
