Невозможно построить EntityManagerFactory в тесте JUnit

Приложение приносит мне ошибки при попытке его создания - оно останавливается на тесте, которое просто создает EntityManagerFactory. У меня также есть основной метод с некоторым кодом, который сохраняет объекты в базе данных, но запуск без тестов работает хорошо.Невозможно построить EntityManagerFactory в тесте JUnit

На основе представленной трассировки стека вы недостающую зависимость для проверки компонента.

Попробуйте добавить гибернации-валидатор как зависимость в вашем pom.xml:

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-validator</artifactId> 
    <version>5.1.2.Final</version> 
</dependency>

Спасибо, это сработало. Хотелось бы, чтобы я спросил раньше, потратил на это больше времени, чем я хотел бы признать. – Matthew
