Created Nov 17, 2016
Stash of a spike to grab TickSpec Scenarios during the xUnit 2 discovery phase in order to surface the Scenarios as individual Tests in the VS Test Runner list. AFAICT this will never work as it will require all of TickSpec's object model and more (the compiled code) to be serializable

The relationship between state machines and event sourcing

A state machine is defined as follows:

  • Input - a set of inputs
  • Output - a set of outputs
  • State - a set of states
  • S0 ∈ S - an initial state
  • T : Input * State -> Output * State - a transition function

If you model your services (aggregates, projections, process managers, sagas, whatever) as state machines, one issue to address is management of State. There must be a mechanism to provide State to the state machine, and to persist the resulting State for subsequent retrieval. One way to address this is by storing State in a key-value store. Another way is to use a SQL database. Yet another way is event sourcing. The benefit of event sourcing is that you never need to store State itself. Instead, you rely on the Output of a service to reconstitute state. In order to do that, the state machine transition function needs to be factored into two functions as follows:
