Question

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/applicationContext-test.xml"})
@Transactional
public class MyServiceTest {

    @Resource(name="myService")
    public MyService myService;

    @Test
    public void testSeomthing() {
    //do some asserts using myService.whatever()
    }
}

However the tests are based on data I migrate in, so every time I run my suite of tests I want to execute my unrelated migration code. I don’t want to run a @Before in each test class. I want to run it once at beginning of complete test process, where can I put this ?

Answer 1

I would advice you to create a test bean somewhere with startup logic invoked in @PostConstruct:

@Service
public class TestBean {

    @PostConstruct
    public void init() {
        //startup logic here
    }

}

Obviously this bean should only be created for tests, the easiest way to achieve this is to place it in src/test/java in a package that is component-scanned by Spring for @Service-annotated classes.

Note: you must remember that @PostConstruct is not running in a transaction! See How to call method on spring proxy once initialised.
