Callbacks Testing SimApp

This testing directory is a duplicate of the ibc-go testing directory. It is only here as a way of creating a separate SimApp binary to avoid introducing a dependency on the callbacks module from within ibc-go.

}

This is a mock contract keeper used for testing. It is not wired up to any modules. It implements the interface functions expected by the ibccallbacks middleware so that it can be tested with simapp. The keeper is responsible for tracking two metrics:

  • number of callbacks called per callback type
  • stateful entry attempts

The counter for callbacks allows us to ensure the correct callbacks were routed to and the stateful entries allows us to track state reversals or reverted state upon contract execution failure or out of gas errors.
