Testing Email w/ Pony and RSpec in Rails 3.1

Question
I tried using this How do I test Pony emailing in a Sinatra app, using rspec? to test a Rails 3.1 app sending emails. The sending works fine, but I'm having a hard time getting the tests to work. Here's what I have so far ...
spec/spec_helper.rb
config.before(:each) do
do_not_send_email
end
.
.
.
def do_not_send_email
Pony.stub!(:deliver) # Hijack to not send email.
end
and in my users_controller_spec.rb
it "should send a greeting email" do
post :create, :user => @attr
Pony.should_receive(:mail) do |params|
params[:to].should == "nuser@gmail.com"
params[:body].should include("Congratulations")
end
end
and I get this ...
Failures:
1) UsersController POST 'create' success should send a greeting email Failure/Error: Pony.should_receive(:mail) do |params| (Pony).mail(any args) expected: 1 time received: 0 times # ./spec/controllers/users_controller_spec.rb:121:in `block (4 levels) in '
It looks like Pony's not getting an email, but I know the real email is getting sent out.
Any ideas?
Solution
Here's what I finally ended up with for the test ...
it "should send a greeting email" do
Pony.should_receive(:deliver) do |mail|
mail.to.should == [ 'nuser@gmail.com' ]
mail.body.should =~ /congratulations/i
end
post :create, :user => @attr
end
The Pony.should_rececieve needs :deliver (not :mail), the do/end was changed a bit, and the post was done after the setup.
Hope this helps someone else.
OTHER TIPS
I know this is an old question but there is another way to test this. Version 1.10 of Pony added override_options
. Pony uses Mail to send email. override_options
lets you use the TestMailer functionality that is built into Mail. So you can set up your test like this:
In spec_helper
require 'pony'
Pony.override_options = { :via => :test }
In your test
before do
Mail::TestMailer.deliveries.clear
end
it 'some test' do
# some code that generates an email
mail = Mail::TestMailer.deliveries.last
expect(mail.to).to eql 'some@email.com'
end
