title: Use one spring boot context through all SpringBootTests
body: <p>I want to be able to cache application context through different classes with tests using junit.</p>
  
  <p>Test classes are declared this way:</p>
  
  <pre><code>@SpringBootTest
  @RunWith(SpringRunner.class)
  public class SomeIntegrationTest {
  }
  </code></pre>
  
  <p>I saw this question <a href="https://stackoverflow.com/questions/8501975/reuse-spring-application-context-across-junit-test-classes">Reuse spring application context across junit test classes</a> but in this case I don't use any xml and I want to start context completely, not just few beans from it, so <code>@SpringBootTest</code> is more suitable than <code>@ContextConfiguration</code>, if I got it right.</p>
