/**
* FailoverTest provides testing of fail-over over a local-circuit implementation. The circuit being tested may be
* against an in-vm broker or against an external broker, with the failure mechanism abstracted out of the test case.
* Automatic failures can be simulated against an in-vm broker. Currently the test must interact with the user to
* simulate failures on an external broker.
*
* Things to test:
* In tx, failure duing tx causes tx to error on subsequent sends/receives or commits/rollbacks.
* Outside of tx, reconnection allows msg flow to continue but there may be loss.
*

*
* @todo This test is designed to be run over a local circuit only. For in-vm using automatic failures, for external
* brokers by prompting the user (or maybe using a script). Enforce the local-circuit only nature of the tests as
* well as thinking about how other local-circuit tests might be implemented. For example, could add a method
* to the framework base case for local only tests to call, that allows them access to the local-circuit
* implementation and so on.
*
* @todo More. Need to really expand the set of fail-over tests.
