package mock
package mock returns a Client implementation that
accepts various (mock) implementations of the various methods.
This implementation is useful for using in tests, when you don't
need a real server, but want a high-level of control about
the server response you want to mock (eg. error handling),
or if you just want to record the calls to verify in your tests.
For real clients, you probably want the "http" package. If you
want to directly call a tendermint node in process, you can use the
"local" package.

// Client wraps arbitrary implementations of the various interfaces.
// We provide a few choices to mock out each one in this package.
// Nothing hidden here, so no New function, just construct it from
// some parts, and swap them out them during the tests.

var _ client.Client = Client{}

// It can also be used to configure mock responses.

// GetResponse will generate the apporiate response for us, when
// using the Call struct to configure a Mock handler.

// set then that will always be returned. If both are set, then
// we return Response if the Args match the set args, Error otherwise.
