At this stage, you should be fairly comfortable with concurrency in Go and should be able to implement basic goroutines and concurrent mechanisms with ease.
We have also dabbled in some distributed concurrency patterns that are managed not only through the application itself, but also through third-party data stores for networked applications that operate concurrently in congress.
Earlier in this book, we examined some preliminary and basic testing and logging. We looked at the simpler implementations of Go's internal test tool, performed some race condition testing using the race tool, and performed some rudimentary load and performance testing.
However, there's much more to be looked at here, particularly ...
