/*
Package mocks provides mocks that can be used for testing applications
that use Sarama. The mock types provided by this package implement the
interfaces Sarama exports, so you can use them for dependency injection
in your tests.

All mock instances require you to set expectations on them before you
can use them. It will determine how the mock will behave. If an
expectation is not met, it will make your test fail.

NOTE: this package currently does not fall under the API stability
guarantee of Sarama as it is still considered experimental.
