Asserting event logs

[veigajoao]

On building integration tests for complex smart contracts it is very important to test correct logging of events. Events are the bridge of data between the smart contract's state history and user facing frontend applications. Usually a complex service involves a indexing service that picks up events and logs them to a DB instance, for further processing.

Therefore, it seems very relevant to test the emission of events on integration tests, yet I've found no framework for doing so in workspaces.js' documentation.

Am I missing something? Is there a way to perform assertions on emitted events in the current version?

If not, I believe this would be a very beneficial feature add.
