Question

I would like to register some web scopes to the spring context in my @BeforeTest method. But it turns out that spring context is still null at that point.

The test runs fine though, if I change into @BeforeMethod. I wonder how I can access the context in @BeforeTest, because I don’t want the scope registration code to be repeated for each test methods.

Below are my code snippets.

public class MyTest extends MyBaseTest {
    @Test public void someTest() { /*...*/ }
}

@ContextConfiguration(locations="/my-context.xml")
public class MyBaseTest extends AbstractTestNGSpringContextTests {
    @BeforeTest public void registerWebScopes() {
        ConfigurableBeanFactory factory = (ConfigurableBeanFactory)
                this.applicationContext.getAutowireCapableBeanFactory();
        factory.registerScope("session", new SessionScope());
        factory.registerScope("request", new RequestScope());
    }   

    /* some protected methods here */
}

Here’s the error message when running the test:

FAILED CONFIGURATION: @BeforeTest registerWebScopes
java.lang.NullPointerException
    at my.MyBaseTest.registerWebScopes(MyBaseTest.java:22)

Call springTestContextPrepareTestInstance() in your BeforeTest method.
