Suggestion - test connection async

[lucasjoao]

Using the api I found one situation where I need make the testConnection async in the same way that is possible send a email async.

Today I solved this making the call to testConnection async, but I was thinking if will not be better the api provide this solution? What do you think @bbottema?

In your situation, how are you handling exceptions in case testConnection() fails?

Probably I will use callback to show some message to the user. Did I answer your question @bbottema? 🤔
