Mockito doesn't mock in spring mvc controller test - spring-mvc

Question

I have controller
#Controller
public class AuthorController {
#Autowired
private AuthorDAO authorDao;
#RequestMapping("/authors")
public String showAuthor(#RequestParam String name, ModelMap model) {
Author author = authorDao.findByName(name);
model.addAttribute("author", author);
return "authors";
}
}
I wrote test for it
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {"classpath:test-application-context.xml"})
public class AuthorControllerTest {
private static final String JACK_C = "Jack C.";
#Autowired
AuthorController controller;
#Test
public void testShowAuthor() {
Author expectedAuthor = new Author();
AuthorDAO daoMock = mock(AuthorDAO.class);
when(daoMock.findByName(JACK_C)).thenReturn(expectedAuthor);
ModelMap model = new ModelMap();
String view = controller.showAuthor(JACK_C, model);
assertEquals("View name is incorrect","authors", view);
assertSame(expectedAuthor, model.get("author"));
verify(daoMock).findByName(JACK_C);
}
}
test-application-context.xml:
<context:annotation-config />
<context:component-scan base-package="com.github.futu" />
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property
name="url" value="jdbc:mysql://localhost:3306/blog" /> <property name="username"
value="blogger" /> <property name="password" value="blogger" /> </bean>
<bean id="com.github.futu.dao.AuthorDAO" class="com.github.futu.dao.impl.AuthorDAOXml"/>
<bean id="com.github.futu.dao.PostDAO" class="com.github.futu.dao.impl.PostDAOXml" />
<bean id="validator" class="com.github.futu.validator.PostValidator" />
But real dao is called. What have I missed?

You're creating a mock here
AuthorDAO daoMock = mock(AuthorDAO.class);
that is completely unrelated to your controller injected into your test class
#Autowired
AuthorController controller;
Of course the autowired AuthorDao target is going to come from your XML configuration
#Autowired
private AuthorDAO authorDao;
Ideally you would change your XML configuration only produce a #Controller bean and add a setter to it to set the AuthorDao from within the test, using your mock.
