Strange issue with the 'its' construct

Testing RSpec
1

The ‘its’ construct seems to not be working for me. I have narrowed it
down to a basic example that I think should be working. Note that when I
use a normal ‘it’ block with a subject in it, that works fine.

Any insights would be welcome: sdfsdf · GitHub

Cheers, Tom.

mail.from = “[email protected]”

it "should have the correct from address" do

This passes as expected.

it “should have the correct from address” do
subject.from.should == [‘[email protected]’]
end

I don’t understand why this fails.

its(:from) { should == [‘[email protected]’] }
end
end

Please file a bug at Lighthouse - Beautifully Simple Issue Tracking
if there’s not one already.

I was unable to find one, so I created this:
https://rspec.lighthouseapp.com/projects/5645-rspec/tickets/998-explicit-subject-block-in-a-controller-spec-returns-the-controller-instead-of-the-subject-defined-in-the-example-group

Another finding is that this only occurs when running the file from
spec/controllers, it’s fine when run from spec/models. Details are on
the ticket.

Thanks, Tom
