title: Spring-Boot module based integration testing
body: <p>I have a multi-module Spring-Boot project. 
  I was wondering how I can set up integration testing just to test Spring Data JPA repositories? The following approach fails with this exception: 
  HV000183: Unable to load 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath.</p>
  
  <p>Since this module does not depend on the web module, there is no web application that can be started. </p>
  
  <pre><code>@RunWith(SpringJUnit4ClassRunner.class)
  @IntegrationTest
  @SpringApplicationConfiguration(classes = TestConfiguration.class)
  class CardInfoRepositoryIT {
  
      @Autowired CardInfoRepository cardInfoRepository;
  
      @Test
      void testLoadData() {
          assert cardInfoRepository.findAll().size() == 1
      }
  
  }
  </code></pre>
