  <p>I think this happens because I have a <code>RestTemplate</code> bean inside my <code>Application</code> class like this:</p>
  
  <pre><code>@SpringBootApplication
  public class TestApplication {
  
      public static void main(String[] args) {
          SpringApplication.run(TestApplication.class, args);
      }
  
      @Bean
      public RestTemplate restTemplate(RestTemplateBuilder builder) {
          return builder.build();
      }
  }
  </code></pre>
  
  <p>This is my Test Class:</p>
  
  <pre><code>@RunWith(SpringRunner.class)
  @DataJpaTest
  public class CityRepositoryTest {
  
      @Autowired
      private TestEntityManager entityManager;
  
      @Autowired
      private CityRepository cityRepository;
  
      private City city;
  
      @Before
      public void init() {
          city = new City();
          city.setName("New York");
          city.setImage("http://www.mockimage.com");
      }
  
      @Test
      public void findByNameShouldReturnCity() throws Exception {
          this.entityManager.persist(city);
          Optional&lt;City&gt; hasCity = this.cityRepository.findByNameIgnoreCase("New York");
          city = hasCity.get();
          assertThat(city.getId()).isNotNull();
          assertThat(city.getName()).isEqualTo("New York");
          assertThat(city.getImage()).isEqualTo("http://www.mockimage.com");
      }
  
      @Test
      public void findByNameStartingWithShouldReturnCity() throws Exception {
          this.entityManager.persist(city);
          Optional&lt;City&gt; hasCity = this.cityRepository.findByNameStartingWithIgnoreCase("New");
          city = hasCity.get();
          assertThat(city.getId()).isNotNull();
          assertThat(city.getName()).isEqualTo("New York");
          assertThat(city.getImage()).isEqualTo("http://www.mockimage.com");
      }
  
      @Test
      public void findByNameWhenNoCityShouldReturnFalse() throws Exception {
          this.entityManager.persist(city);
          Optional&lt;City&gt; hasCity = this.cityRepository.findByNameStartingWithIgnoreCase("Ohaio");
          assertThat(hasCity.isPresent()).isFalse();
      }
  }
