Use checks (like asserts) to make sure your tests are functionally correct, and setup test pass/fail criteria using thresholds to open up the door for automated load testing with CI/CD tools and services.
Plot a single, high-level performance metric collected over multiple test runs to locate patterns of performance degradation or improvement, and more easily validate the performance impact of code and infrastructure changes over time. Read more about performance trending.
