Hi,

I’m trying to install exception notification plugin and test it with  
rspec.  
The problem that I have is that when running the server in production  
mode : at the end of the log i get this when I have a critical error

rendering section “request”  
rendering section “session”  
rendering section “environment”  
rendering section “backtrace”  
Sent mail to removed\_email\_address@domain.invalid

but the spec fails :

ActionMailer::Base.delivery\_method = ‘test’  
ActionMailer::Base.perform\_deliveries = false  
ActionMailer::Base.deliveries = []  
@size\_before = ActionMailer::Base.deliveries.count  
lambda { get ‘dummy\_method\_raises\_exception’ }.should raise\_error  
(RuntimeError)  
ActionMailer::Base.deliveries.count.should eql(@size\_before + 1) \<====  
here I got 0 and not 1

Does someone have an idea about this problem?

Thank you by advance  
-Yoann

A very similar topic came up recently on the cukes group  
([http://groups.google.com/group/cukes/browse\_thread/thread/79d45e6e8a4b5ce0](http://groups.google.com/group/cukes/browse_thread/thread/79d45e6e8a4b5ce0)  
). Maybe the thread will be of some use to you in puzzling this out.

Setting ‘ActionMailer::Base.perform\_deliveries = false’ means that  
nothing makes it to the ActionMailer::Base.deliveries, so you will get  
0.

deliver calls deliver! which calls perform\_delivery\_#{delivery\_method}  
iff perform\_deliveries is true.  
as you can see here

thats the thing that polulates the ActionMailer::Base.deliveries.

Hope i’m on the right track and this helps.  
Niko.
