Say I have a class that sends mail. It has a method with this in it:
Net::SMTP.start(host) { |smtp|
smtp.send_mail(message, sender, *recipients)
}
How can I best unit test this?
Should I alias Net::SMTP.start to something else and replace it with a
mock implementation in my test case’s startup, then restore it in
teardown?
Any libraries or examples of where this is done elegantly?
