  </code></pre>
  
  <p>And tried to make a test:  </p>
  
  <pre><code>ExtendWith(SpringExtension.class)
  @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
  public class UserControllerTest {
  
      @Test
      public void register() {
      }
  }
  </code></pre>
  
  <p>But there is not the <code>SpringExtension.class</code>, I can't import it.</p>
  
  <pre><code>Error:(7, 13) java: cannot find symbol
    symbol: class SpringExtension
  </code></pre>
  
  <p>How to fix my <code>pom.xml</code> or maybe can I use a some another class?<br>
  <strong>P.S.</strong> I'm a noobie in the Spring so my question may be stupid but I can't get how to resolve.</p>
