title: Is it possible to verify tested object method call with Mockito?
body: <p>I' ve got some business logic class:</p>
  
  <pre><code>public class SomeService {
      public void doFirst() {}
  
      public void doSecond() {
          doFirst();
      }
  }
  </code></pre>
  
  <p>and test for it:</p>
  
  <pre><code>public class SomeServiceTest {
  
      private SomeService service;
  
      @Before
      public void setUp() {
          service = new SomeService();
      }
  
      @Test
      public void doSecond_someCondition_shouldCallFirst() {
  
          // given
          ...
  
          // when
          service.doSecond();
  
          //then
          how to verify doFirst() was called? 
      }
  }
  </code></pre>
  
  <p>How to verify doFirst() was called not on mock, but real service?</p>
