Hi all, I have this model (see the attachment). I has an after\_save  
filter which sends mail. But I don’t know how to test it. Most things I  
find about testing the sending of e-mails is about the ActionMailer  
class.

Does anyone know how I can test this method properly  
(send\_mail\_about\_new\_deposit)?

Thanks in advance!

we use ActionMailer very often, but normally do only this simple test:

first:  
ActionMailer::Base.deliveries.clear

then create/save the deposit and with:  
assert\_equal(1, ActionMailer::Base.deliveries.length)

make sure, that the mail was sent

Ah thanks! Looks very simple and is exactly what I want.
