Class MockitoJUnitRunner

java.lang.Object

org.junit.runner.Runner

org.mockito.junit.MockitoJUnitRunner

All Implemented Interfaces:

Describable, Filterable

Direct Known Subclasses:

MockitoJUnitRunner, MockitoJUnitRunner.Silent, MockitoJUnitRunner.Strict

public class MockitoJUnitRunner
extends Runner
implements Filterable

Compatible with JUnit 4.4 and higher, this runner adds following behavior:

• (new since Mockito 2.1.0) Detects unused stubs in the test code. See UnnecessaryStubbingException. Similar to JUnit rules, the runner also reports stubbing argument mismatches as console warnings (see MockitoHint). To opt-out from this feature, use @RunWith(MockitoJUnitRunner.Silent.class)
• 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().

Runner is completely optional - there are other ways you can get @Mock working, for example by writing a base class. Explicitly validating framework usage is also optional because it is triggered automatically by Mockito every time you use the framework. See javadoc for Mockito.validateMockitoUsage().

 @RunWith(MockitoJUnitRunner.class)
 public class ExampleTest {
 
     @Mock
     private List list;
 
     @Test
     public void shouldDoSomething() {
         list.add(100);
     }
 }
