Your test is annotated with @ContextConfiguration(classes = EmployeeRepository.class)

However, the classes property of this annotation should reference configurations (class annotated with @Configuration like your AppConfig). So you are launching your test without a configuration for spring-data and your repository.

If you want to test your repository, you should create a @Configuration with the @EnableJpaRepositories and an in-memory database.
