Taurus is a handy application and service performance testing tool written in Python. It wraps many performance testing executors, including Gatling and Locust. You can run it from the command line and easily integrate it with continuous delivery pipelines to run performance tests at different stages of the pipeline. Taurus also has great reporting either as console text-based output or integrated with an interactive web UI. Our teams have found that configuring Taurus YAML files is easy because you can use multiple files to describe each test scenario and refer to underlying executer's scenario definitions.
