Interface MockitoRule

All Superinterfaces:

org.junit.rules.MethodRule

public interface MockitoRule
extends org.junit.rules.MethodRule

Since 2.1.0, JUnit rule emits stubbing warnings and hints to System output (see also MockitoHint). The JUnit rule can be used instead of MockitoJUnitRunner. It requires JUnit at least 4.7. This rule adds following behavior:

• Since 2.1.0, stubbing warnings and hints are printed to System output. Hints contain clickable links that take you right to the line of code that contains a possible problem. Please give us feedback about the stubbing warnings of JUnit rules in the issue tracker (issue 384). It's a new feature of Mockito 2.1.0. It aims to help debugging tests. If you wish the previous behavior, see silent(). However, we would really like to know why do you wish to silence the warnings! See also MockitoHint.
• Initializes mocks annotated with Mock, so that explicit usage of MockitoAnnotations.initMocks(Object) is not necessary. Mocks are initialized before each test method.
• Validates framework usage after each test method. See javadoc for Mockito.validateMockitoUsage().

Example use:

 public class ExampleTest {

     @Rule
     public MockitoRule rule = MockitoJUnit.rule();

     @Mock
     private List list;

     @Test
     public void shouldDoSomething() {
         list.add(100);
     }
 }

Please give us feedback about the stubbing warnings of JUnit rules. It's a new feature of Mockito 2.1.0. It aims to help debugging tests. We want to make sure the feature is useful. We would really like to know why do you wish to silence the warnings! See also MockitoHint.
