RSpec use_transactional_fixtures = false not working

Question

Настройка use_transactional_fixtures = false в моем файле spec_helper.rb, хотя, когда я смотрю на вывод моего тестового журнала, кажется, что транзакция все еще используется? Почему это так и как я удаляю транзакцию?

rails_helper.rb ...

спецификацию, которая отображает проблему ....

Answer 1

Когда вы устанавливаете config.use_transactional_fixtures = false, вы говорите RSpec, чтобы не беспокоиться о чистке базы данных каждый раз, когда она запускает новый пример. Иногда я устанавливаю значение false, потому что вместо этого я использую database_cleaner (GitHub).

Итак, на основе ваших журналов, я считаю, RSpec делает именно то, что он должен делать.

Вы можете прочитать об этой настройке в RSpec manual
