Rspec: ActionMailer::Base.deliveries должен быть пустым

Question

Проверка заполнения контактной формы без заполнения одного из обязательных полей в одном тесте, а затем заполнение поля honey_pot в другом тесте. Тесты при заполнении действительной информации проходят, но две другие спецификации не выполняются.

Обновление Я проводил тест пару раз, и иногда все тесты проходят. В других случаях одни и те же спецификации не работают.

Терминальный выход

  3) Pages Home page it should behave like all static pages Footer Contact Form when honeypot is filled does not send an email

Answer 1

Я смог получить прохождение спецификаций, очистив ActionMailer::Base.deliveries до и после каждой спецификации, где я проверял поставки. Я также переписал тесты, чтобы сделать его более сухим, используя before(:each) а также after(:each) методы описаны в документации Rspec. Обнови еще лучше, around(:each)
