如何使用参数化运行JUnit SpringJUnit4ClassRunner？

Question

由于重复的@RunWith注释，以下代码无效：

@RunWith(SpringJUnit4ClassRunner.class)
@RunWith(Parameterized.class)
@SpringApplicationConfiguration(classes = {ApplicationConfigTest.class})
public class ServiceTest {
}

但是，如何结合使用这两个注释？

至少有两个选项可以做到这一点：

1. 以下http://www.blog.project13.pl/index.php/coding/1077/runwith-junit4-with-both-springjunit4classrunner-and-parameterized/

您的测试需要看起来像这样：

         @RunWith(Parameterized.class)
     @ContextConfiguration(classes = {ApplicationConfigTest.class})
     public class ServiceTest {

         private TestContextManager testContextManager;

         @Before
         public void setUpContext() throws Exception {
             //this is where the magic happens, we actually do "by hand" what the spring runner would do for us,
            // read the JavaDoc for the class bellow to know exactly what it does, the method names are quite accurate though
           this.testContextManager = new TestContextManager(getClass());
           this.testContextManager.prepareTestInstance(this);
         }
         ...
     }

1. 有一个github项目https://github.com/mmichaelis/spring-aware-rule，它建立在以前的博客上，但是以一种通用的方式添加了支持

        @SuppressWarnings("InstanceMethodNamingConvention")
    @ContextConfiguration(classes = {ServiceTest.class})
    public class SpringAwareTest {

        @ClassRule
        public static final SpringAware SPRING_AWARE = SpringAware.forClass(SpringAwareTest.class);

        @Rule
        public TestRule springAwareMethod = SPRING_AWARE.forInstance(this);

        @Rule
        public TestName testName = new TestName();

        ...
    }

因此，您可以让一个基本类实现其中一种方法，并从中继承所有测试。
