Question

I’ve tried the answers to these questions: 1, 2. The first one indicates it might be a caching issue (and suggests running rake tmp:clear). The second one suggests forcing ENV['RAILS_ENV'] = 'test' in spec_helper.rb since rake is run in ‘development’. I’ve also tried removing the vcr gem completely, but this has no effect either.

This comment gives more details on how the problem might be due to a dirty environment (since rake starts in ‘development’, but rspec is run in ‘test’).

The spec in question uses capybara and capybara-webkit. It passes when run via bundle exec rake spec:requests but fails when it’s run in the suite via bundle exec rake. The html that capybara sees is different in both cases, and when run in the suite it doesn’t see the element #movie_imdb_id.

I’m using gem versions rspec (2.11.0), capybara (1.1.3), and capybara-webkit (0.12.1).

Rspec message:

Failures:

  1) Imdb credits get credits should have a credits table
     Failure/Error: wait_until { page.find('#movie_imdb_id').visible? }
     Capybara::ElementNotFound:

Answer 1

The problem was actually the gem rails_admin and how it was interacting with rake. It was fixed by adding the following to spec_helper.rb:

ENV['SKIP_RAILS_ADMIN_INITIALIZER'] = 'false'
