Spring-Autowiring happens after @BeforeClass when running test with maven-surefire

Question

I have some problems with dependency injection (Spring autowiring) and maven-surefire. The following test works without problems when run in eclipse with TestNG: The service-object is injected, then the @BeforeClass-method is called.

@TransactionConfiguration(defaultRollback=false)
@ContextConfiguration(locations={"/testContext.xml"})
public class MyServiceTest extends AbstractTransactionalTestNGSpringContextTests {


@Autowired
private MyService service;

@BeforeTest
public void setup() {
    System.out.println("*********************"+service);
    Assert.assertNotNull(service);
}

However, when I run the very same testcase with maven-surefire, first setup() is called, which causes the test to fail:

[INFO] --- maven-surefire-plugin:2.7.2:test (default-test) @ myserver ---
[INFO] Surefire report directory: D:\...

2011-03-04 11:08:57,462 DEBUG  ractGenericContextLoader.loadContext          - Loading ApplicationContext for locations [classpath:/testContext.xml].

How can I solve this problem? If I replace @BeforeClass with @Test it works in maven as in TestNG's eclipse plugin.

maven-surefire-plugin:2.7.2

Eclipse: Helios Service Release 1

jdk1.6.0_14

TestNG: 5.14.10

I don't know very much about maven-surefire and its integration with spring. But, to have spring components injected, an object also must be initialized by spring. — bluefoot, Mar 04 '11 at 10:41
I had a similar issue but JUnit: I was starting/stopping Jetty in `@BeforeClass`/`@AfterClass` annotated methods in a test class, and it didn't work, because autowiring had not happened yet. — MarcoS, Mar 04 '11 at 12:59

Additionally, until this issue is fixed, if things still aren't working for you after following the previous advice OR you do not wish your code to be executed before every single method, then add the following code to your test class:

@Override
@BeforeSuite
protected void springTestContextPrepareTestInstance() throws Exception {
    super.springTestContextPrepareTestInstance();
}

This ensures that the Spring Context will be prepared before your @BeforeClass methods are executed.

*note, I posted this answer since in the title you're asking about @BeforeClass, even though there is no usage of @BeforeClass in your sample code.

Use @BeforeMethod, not @BeforeTest.

I met the same problem but could not find "@BeforeMethod" or "@BeforeTest" annotation in spring-test or jUnit,Where can I find them? Thanks. – Allen Jun 26 '15 at 05:24

It's a TestNG annotation, not JUnit. – Cedric Beust Jun 27 '15 at 05:56

I agree with Cedric: use @BeforeMethod instead of @BeforeTest, since Spring's dependency injection occurs in an @BeforeClass method.

There was a problem when I use @PostConstruct: the static method use this annotation was invoked before every test case , but what I wanted is to be invoked only once. – Allen Jun 26 '15 at 05:27

Check if you have spring-asm dependency as well. If you have one it will conflict with spring-core dependency. I removed the asm dependency and this worked for me.
