Hands-on Chaos Testing with OpenText Performance Engineering

This guide provides a detailed tutorial on implementing chaos testing using OpenText Professional Performance Engineering in conjunction with Gremlin. It outlines the necessary preparations, including system requirements and initial setups, for conducting chaos tests. The document explains how to add chaos testing to an application, create a scenario within Gremlin for simulating CPU and latency attacks, and perform the chaos test using the Controller. A specific focus is placed on configuring the testing environment, including virtual user simulations and managing various attack parameters. Additionally, it describes the process of analyzing test results, including how to view and interpret key metrics like throughput and response time. The guide emphasizes the importance of chaos engineering in improving infrastructure resilience, as well as the ability to anticipate failures and enhance system robustness. By following this structured approach, developers can better integrate chaos testing into their development lifecycle and contribute to more robust application performance.
