Проблема с запуском JUnit Test внутри приложения Spring MVC. Тест 1 (insertTweet), кажется, работает нормально, однако на Test 2 я получаю исключение LazyInitializationException (см. Полный stactrace ниже). Я понимаю, почему он брошен, но не уверен, почему сеанс закрывается и как его снова открыть в начале каждого теста 2 (или сохранить существующий сеанс открытым для завершения остальных тестов)? Я вложил весь StackTrace, который был брошен вместе с Test Classes.
