Failure testing is a fundamental piece of Twitters reliability engineering. Over the years, we developed a rich toolchain that allows us to detect and fix scalability problems long before they happen. In this talk, well cover some of the strategies we employ and discuss our always evolving approach to API stress testing and its unit test equivalent, redline testing.]]>
