title: How to exclude *AutoConfiguration classes in Spring Boot JUnit tests?
body: <p>I tried:</p>
  
  <pre><code>@RunWith(SpringJUnit4ClassRunner.class)
  @EnableAutoConfiguration(exclude=CrshAutoConfiguration.class)
  @SpringApplicationConfiguration(classes = Application.class)
  @WebAppConfiguration
  public class LikeControllerTest {
  </code></pre>
  
  <p>However the CRaSSHD still starts up. While currently it doesn't harm the test, I'd like to disable unnecessary modules during unit testing to speed up and also avoid potential conflicts.</p>
