I'm trying to run more tests using gitlab debian package, now with RAILS_ENV=test. But email related tests fail. ``` 1) BuildEmailWorker#perform sends mail Failure/Error: Notify.build_success_email(build_id, recipient).deliver_now ArgumentError: An SMTP From address is required to send a message. Set the message smtp_envelope_from, return_path, sender, or from address. # ./app/workers/build_email_worker.rb:10:in `block in perform' # ./app/workers/build_email_worker.rb:6:in `each' # ./app/workers/build_email_worker.rb:6:in `perform' # ./spec/workers/build_email_worker_spec.rb:19:in `block (3 levels) in <top (required)>' ``` I think this is because email address is set as environment variable in debian, ``` GITLAB_EMAIL_FROM="no-reply@localhost" GITLAB_EMAIL_DISPLAY_NAME="Gitlab" GITLAB_EMAIL_REPLY_TO="no-reply@localhost" ``` Before the tests run, I checked the variable is set with ` echo email: "GITLAB_EMAIL_FROM"` and it outputs `email: "no-reply@localhost"` as expected. I think the tests are not expecting to read this from environment variables. cc @stanhu
