Scheduling load tests and persisting output with k6

The text is a tutorial within a series on using k6 for performance testing, specifically focusing on storing k6 test results locally and scheduling load tests using CircleCI's scheduled pipelines feature. It builds on previous tutorials by demonstrating how to persist test outputs in JSON format, which allows for detailed analysis of test metrics, including request timestamps and execution times. The tutorial also guides users on configuring scheduled pipelines in CircleCI to automate test runs during low-traffic periods, optimizing resource usage and ensuring consistent testing at specified times. This approach allows users to efficiently review and compare test data while ensuring load tests are executed without disrupting regular system operations.
