C# Class ChaosTest.ChaosService.ChaosService

This stateful service keeps inducing failovers and faults - chosen probabilistically - to the cluster, using ChaosTestScenario from Microsoft.ServiceFabric.Testability under the hood, hiding the fact that ChaosTestScenario runs in unit of iteration, giving the impression that the fault inducing is perennial.

Inheritance: StatefulService
