摘要: As the cloud era begins and failures become commonplace, failure recovery becomes a critical factor in availability, reliability performance of services. Unfortunately, problems still take place, causing downtimes, data loss, many other problems. We propose new testing framework for recovery: FATE (Failure Testing Service) DESTINI (Declarative Specifications). With FATE, is systematically tested face multiple failures. DESTINI, correct specified clearly, concisely, precisely. have integrated our to several systems (e.g., HDFS [33]), explored over 40,000 scenarios, wrote 74 specifications, found 16 bugs, reproduced 51 old bugs.
