Spring JUnit testing with #Autowired annotation - spring

Question

I´m having issues with my test cases after having introduced #Autowired in one of the classes under test.
My testcase now looks like this:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations={"/applicationContext.xml", "/spring-security.xml"})
public class StudentRepositoryTest extends AbstractDatabaseTestCase {
private StudentRepository studentRepository;
private CompanyRepository companyRepository;
private Student testStudent;
private Company testCompany;
#Before
public void setUp() {
studentRepository = new StudentRepository();
studentRepository.setJdbcTemplate(getJdbcTemplate());
testStudent = Utils.testStudentNoApplication();
}
#Test
....
}
StudentRepository now looks like this:
#Service
public class StudentRepository extends AbstractRepository<Student> {
...
private PasswordEncoder passwordEncoder;
private MailService mailService;
public StudentRepository() {
// TODO Auto-generated constructor stub
}
#Autowired
public StudentRepository(MailService mailService, PasswordEncoder passwordEncoder) {
this.mailService = mailService;
this.passwordEncoder = passwordEncoder;
}
Obviously this test case won´t work anymore.
But what changes do I need to make to the testcase for the #Autowired annotation to be picked up by the test case?
EDIT:
I´ve now updated my setUp() to this (I need the password encoder to avoid null password):
#Before
public void setUp() {
//studentRepository = new StudentRepository();
studentRepository = new StudentRepository(mock(MailService.class), ctx.getAutowireCapableBeanFactory().createBean(ShaPasswordEncoder.class));
studentRepository.setJdbcTemplate(getJdbcTemplate());
testStudent = Utils.testStudentNoApplication();
}
My testcase is now running OK, but my testsuite failes with a NullPointerException.
I´m guessing the ApplicationContext is not being Autowired when running the testsuite for some reason?

If you don't want to declare your StudentRepository in one of XML files referenced by #ContextConfiguration and autowire it into the test, you can try to use AutowireCapableBeanFactory as follows:
...
public class StudentRepositoryTest extends AbstractDatabaseTestCase {
...
#Autowired ApplicationContext ctx;
#Before
public void setUp() {
studentRepository = ctx.getAutowireCapableBeanFactory()
.createBean(StudentRepository.class);
...
}
...
}
