春JUnit测试

Question

我想考验我的春天代码：

@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); 
    } 
} 

运行与Eclipse这个测试（作为JUnit测试）只是给出了一个空指针的异常。

我做错了什么？谢谢！

Answer 1

只需添加@RunWith(SpringJUnit4ClassRunner.class)到类：

@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spring-test了点。

Answer 2

您可以添加一个事务性测试基类这样

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

然后wirite您的测试类

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); 
    } 
} 

你不必写在每个测试类
