Print EmittedEvent in `test`

This issue is related to printing event on terminal.

We need to implement Debug trait for EmittedEvent

It is fairly simple, so feel free to open a PR for that. Alternatively you can just access the individual fields data and topics and print those the terminal.

Sure, let me work on it
