Spring JUnit测试

Question

我喜欢测试我的弹簧代码：

@ContextConfiguration(locations = { "/applicationContext.xml" })
@Transactional()
public class Test {

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

使用eclipse运行此测试（作为JUNIT测试）只会产生Nullpointer-Exception。

我做错了什么？ 谢谢！

Answer 1

只需将@RunWith(SpringJUnit4ClassRunner.class)添加到您的类：

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

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

你需要进行spring-test 。

Answer 2

您可以像这样添加Transactional测试基类

@ContextConfiguration(locations = "classpath*:applicationContext.xml")
public class IntegrateTestBase extends AbstractTransactionalJUnit4SpringContextTests {
}

然后你的测试课就开始了

public class Test extends IntegrateTestBase {

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

您不需要在每个测试类中编写@ContextConfiguration和@Transcational
