Abstract: Certain aspects of the present disclosure provide techniques for executing simulated failure scenarios on a computing system using natural language inputs in a domain-specific language. Embodiments includes receiving a failure scenario definition, which may be a natural language input identifying target systems in a distributed computing system, properties, and an expected outcome of a simulated system failure. Commands directed to the identified target systems to simulate a system failure on the identified systems according to the identified properties are generated and transmitted to the identified target systems for execution. The outcome of the simulated system failure is monitored, recorded, and compared to the expected outcome of the simulated system failure. Upon determining that the recorded outcome and expected outcome of the simulated system failure differ, an alert identifying a difference between the recorded outcome and the expected outcome is generated.

Abstract: Various aspects described herein are directed to a method and a system that implement end-to-end automation of software services. A set of test cases may be identified from existing test cases or determined anew for a software system. Virtual test results may be generated at least by executing the set of test cases in parallel on a virtual time or date. The virtual test results may then be used to validate or verify the behaviors of the software system. The virtual time or date is then advanced to the next virtual time or date by a temporal period until a stopping criterion is satisfied.
