Исключение при тестировании сервлета с использованием Mockito

Question

Я новичок в Mockito и пытаюсь выполнить тестирование моих сервлетов с использованием mockito и junit, но, следя за следующим исключением. Может ли кто-нибудь помочь.

pom.xml

<dependency> 
      <groupId>org.mockito</groupId> 
      <artifactId>mockito-all</artifactId> 
      <version>1.10.19</version> 
      <scope>test</scope> 
     </dependency>
