Embedding a Kafka 0.8 broker for testing

Hi,

I would like to embed a Kafka broker in my Java program, for testing
purposes.

The idea is being capable of running a Junit test that starts a local kafka
broker, and then perform tests on some custom producers and consumers.

After searching around, I've found some pieces of code but none of them
seem to work with Kafka 0.8 API.

Does anyone know about any guide/best practice or code example I could use
for this purpose?

Thanks in advance!
