No Runnable methods Error From Base Test class

问题:

I have a A few base test classes that setup common configurations for spring,logging,jndi etc using test execution listeners that are then inherited by subclasses. This is done so tests can just run code without having to worry about getting jndi and logging services in place before being able to run testing code.

Using intellij and invoking "run all tests" from the project base, the IDE attempts to run the base test class as a unit test and gives me the "No runnable methods" error.

I know I could put an empty runnable method in the base class, but I was hoping some one has a better idea.

The Base class is:

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = {
            "classpath:spring-jndi.xml"
    })
    @TestExecutionListeners({
            Log4JSetupListener.class,
            JndiSetupListener.class,
            DependencyInjectionTestExecutionListener.class,
            DirtiesContextTestExecutionListener.class,
            TransactionalTestExecutionListener.class
    })
    public class SpringAppTestCase extends Assert implements ApplicationContextAware {

        protected JndiTemplate jndiTemplate = new JndiTemplate();

        @Autowired
        protected JdbcTemplate jdbcTemplate;

        protected ApplicationContext applicationContext;

        public void setApplicationContext(ApplicationContext ac) {
            this.applicationContext = ac;
        }

    // 
    //    @Test
    //    public void doit(){
    //      // this would prevent blow up but 
    // all subclass tests would run an extra method
    //    }

        protected Logger log = Logger.getLogger(getClass().getName());

}

The error:

java.lang.Exception: No runnable methods

回答1:

Make the parent class abstract or rename it such as it does not end in Test or TestCase.

回答2:

I had the same issue. I was testing without a Test method.

@Test
public void setupTest() {
}

Above method solved the issue.
