ActionMailer not delivering confirmation emails in test environment - Rails 4
问题 I'm using Rails (4.2.6), Ruby (2.2.4), Devise (4.1.1), Capybara (2.7.1), Capybara-email (2.5.0), Email_spec (2.1.0), Rspec (3.4.0), and Postgres (0.18.4) After I upgraded the application from Rails 4.1.15 to 4.2.6, several authentification & registration tests fail. Before the upgrade all tests were properly passing. The code works as expected in the development environment (for example, confirmation emails are sent & viewable in the Rails server terminal). The problem of non-delivered emails
