spring - Java annotations - code simplifications

Question

I am looking for a way to simplify the following code.

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {
        // My configuration classes
})
public class MyServiceTest {
    @Autowired
    private MyService service;

    @Test
    public void myTest() {
        Assert.assertTrue(service != null);
    }
}

I have many configuration classes and I don't want to put them into each test class. So I got the idea to create my own annotation:

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {
        // My configuration classes
})
public @interface IntegrationTests {
}

I try to use it in the following way:

@IntegrationTests
public class MyServiceTest {
    @Autowired
    private MyService service;

    @Test
    public void myTest() {
        Assert.assertTrue(service != null);
    }
}

But it doesn't work. Any idea?

Answer 1

You can place these annotation on a superclass:

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {
        // My configuration classes
})
public abstract class AbstractIntegrationTest { ... }

.

public class MyServiceTest extends AbstractIntegrationTest { ... }

This approach also allows you to declare common @Autowired dependencies in the base class and customize @ContextConfiguration classes in concrete tests.
