`have_enqueued_mail` raising undefined method `to_sym` for Hash #2575

What Ruby, Rails and RSpec versions are you using?

ruby 2.7.3p183 (2021-04-05 revision 6847ee089d) [x86_64-darwin20]
Rails 6.1.4.6
RSpec 3.10
  - rspec-core 3.10.2
  - rspec-expectations 3.10.2
  - rspec-mocks 3.10.3
  - rspec-rails 5.0.3
  - rspec-support 3.10.3

Issue does not manifest on rspec-rails 5.0.2

Observed behaviour

With the following spec:

       expect { subject.send_coach_lead_notification }
         .to have_enqueued_mail(CoachingInquiryMailer, :coach_notification_bookings_promo)

We get:

     NoMethodError:
       undefined method `to_sym' for {}:Hash
       Did you mean?  to_s

This was a passing test before upgrading to rspec-rails 5.0.3

Can you provide an example app?

I presume this is the result of #2566 (and related to #2570 ).

Thanks for reporting.
I wonder how this very basic case fails. It is pretty much covered by this feature test, and we run Ruby 2.7.5p203 with Rails 6.1.4.6, e.g. fresh passing build.

It would be very helpful if you could provide a reproducible example.

jasonkarns · 2022-02-21T22:09:37Z

@pirj pushed an rspec rails repro repo (say that again!) https://github.com/jasonkarns/fluffy-octo-memory

single model without anything special; single mailer. rspec from repo root will reproduce

jasonkarns · 2022-02-21T22:36:40Z

I just installed ruby 2.7.5 and still reproduced. (So you shouldn't need to downgrade to 2.7.3 if you don't wish to)

ruby 2.7.5p203 (2021-11-24 revision f69aeb8314) [x86_64-darwin21]

pirj · 2022-02-22T00:37:43Z

There's definitely a bug in this line:

keywords.each_with_object({}) { |new_hash, keyword| puts new_hash, keyword; new_hash[keyword.to_sym] = hash[keyword] }

Block arguments should be the other way around, |keyword, new_hash|, and that fixes your case.

It's still surprising that this bug has gotten through all of our lines of defence, and how to write a spec to prevent this from re-appearing. Would you like to hack on it?

JonRowe · 2022-02-22T06:25:38Z

Its the result of a munged rubocop fix, it was initially a reduce which does have the args the other way round, so this was working but then broken to comply with the rubocop rule to not use reduce in these scenarios.

Spec wise we miss this because we don't test with an active record object, if you change the repro spec to use a string it doesn't encounter the bug.

I've tried to work up a repo with a fake global id job in our suite which isn't enough, and an active record one but it complains about it not being serialisable

jasonkarns · 2022-02-22T14:55:11Z

I was able to repro with a non-AR class by ensuring the job's param matched GlobalID::Identification:

jasonkarns/fluffy-octo-memory@6dc4eab

class M
   include GlobalID::Identification
   def id
     1
   end
 end

ReproMailer.with(inquiry: M.new).message.deliver_later

pirj · 2022-02-22T19:11:43Z

Nice! Would you like to send a PR with an added spec for this?

JonRowe · 2022-02-22T21:54:40Z

I had a more complex example, but that actually works better, does not reproduce the issue within our test suite though

pirj · 2022-02-24T06:24:01Z

Quick suggestion. Would cd /Users/jasonkarns/Projects/rspec/rspec-expectations git checkout main git pull work? It seems to find the repo locally, but the code there seems to be aged.

jasonkarns · 2022-02-25T14:22:58Z

Yep, apologies. I deleted my comment as soon as I realized it was due to old sibling repos.

JonRowe · 2022-03-07T10:27:06Z

The key to reproducing this was the fact it needed to be tested using a unified mailer which is a later Rails default than our base level
