body: <p>I am writing a junit test for spring data repository. But i can't autowire repository interface. Program is running if i run main method and spring can detect all repositories,services,entities but if i run a test it gives this error :</p>
  <blockquote>
  <p>UnsatisfiedDependencyException: Error creating bean with name
  'repository.BookRepositoryTest': Unsatisfied dependency expressed
  through field 'bookRepository'; nested exception is
  org.springframework.beans.factory.NoSuchBeanDefinitionException: No
  qualifying bean of type 'app.repository.BookRepository' available:
  expected at least 1 bean which qualifies as autowire candidate.
