Stateful simulationΒΆ

Hoverfly Java supports stateful simulation which means a mocked service could return different responses for the same request depends on the current state(s). (for more details, please check out Hoverfly State).

Stateful simulation can be setup via DSL. A simple example is that you can simulate a GET booking API to return a good response if state is not set, but calling the DELETE API will trigger the state transition, and any subsequent requests to the GET API will results a 404 error.


        .willReturn(success("{\"bookingId\":\"1\"\}", "application/json"))

        .willReturn(success().andSetState("Booking", "Deleted"))

        .withState("Booking", "Deleted")

The following state control methods are available:

  • withState(key, value) add a condition for the request to be matched based on the given state (which is a key-value pair)

  • andSetState(key, value) applies to the response to set the state

  • andRemoveState(key) can be applied to the response to remove a state by key.

You can also chain multiple state methods to create more complex scenarios.
