Fault Injection - CI/CD Glossary Definition

Fault injection is deliberately introducing failures, such as latency, errors, or killed processes, to test how a system behaves under adverse conditions. It is the core technique behind chaos engineering experiments.

Examples

Adding 500 ms of network delay, returning HTTP 503 from a dependency, or terminating a pod with a tool like Chaos Mesh all reveal whether retries, timeouts, and fallbacks actually work.
