Integrating resilience testing, particularly Chaos Engineering, into the Software Development Life Cycle (SDLC) involves nuanced decisions tailored to an organization's goals and infrastructure. Resilience testing is divided into exploratory and verification types, with exploratory tests being more unpredictable and manual, while verification tests can be automated to assess system response to known failures. Organizations typically automate resilience testing in three main ways: gating release candidates with pre-production tests, conducting tests post-production deployment, and scheduling regular interval tests. Each approach has its trade-offs, balancing pipeline latency, testing accuracy, and deployment frequency. Gremlin offers tools to facilitate these processes, allowing for testing integration through APIs, CI/CD platforms, and scheduling capabilities, and emphasizes the importance of adapting strategies over time as systems and practices evolve.
