试试这个吧:

public class MyTest {
        @Rule
        public TestName testName = new TestName();

        @Rule
        public TestWatcher testWatcher = new TestWatcher() {
            @Override
            protected void starting(final Description description) {
                String methodName = description.getMethodName();
                String className = description.getClassName();
                className = className.substring(className.lastIndexOf('.') + 1);
                System.err.println("Starting JUnit-test: " + className + " " + methodName);
            }
        };

        @Test
        public void testA() {
                assertEquals("testA", testName.getMethodName());
        }

        @Test
        public void testB() {
                assertEquals("testB", testName.getMethodName());
        }
}

输出如下所示:

Starting JUnit-test: MyTest testA
Starting JUnit-test: MyTest testB

注意:如果你的测试是TestCase的子类，这是行不通的!测试运行了，但是@Rule代码从来没有运行过。

一种复杂的方法是通过子类化org.junit.runners.BlockJUnit4ClassRunner来创建自己的Runner。

然后你可以这样做:

public class NameAwareRunner extends BlockJUnit4ClassRunner {

    public NameAwareRunner(Class<?> aClass) throws InitializationError {
        super(aClass);
    }

    @Override
    protected Statement methodBlock(FrameworkMethod frameworkMethod) {
        System.err.println(frameworkMethod.getName());
        return super.methodBlock(frameworkMethod);
    }
}

然后，对于每个测试类，您需要添加一个@RunWith(nameawarerener .class)注释。或者，如果不想每次都记住它，也可以将该注释放在Test超类上。当然，这限制了跑步者的选择，但这可能是可以接受的。

此外，将当前测试名称从Runner中取出并放入框架可能需要一些功夫，但这至少为您提供了名称。

JUnit 5及更高版本

在JUnit 5中，您可以注入TestInfo，这简化了对测试方法的测试元数据注入。例如:

@Test
@DisplayName("This is my test")
@Tag("It is my tag")
void test1(TestInfo testInfo) {
    assertEquals("This is my test", testInfo.getDisplayName());
    assertTrue(testInfo.getTags().contains("It is my tag"));
}

更多信息:JUnit 5用户指南，TestInfo javadoc。

I'd suggest you decouple the test method name from your test data set. I would model a DataLoaderFactory class which loads/caches the sets of test data from your resources, and then in your test case cam call some interface method which returns a set of test data for the test case. Having the test data tied to the test method name assumes the test data can only be used once, where in most case i'd suggest that the same test data in uses in multiple tests to verify various aspects of your business logic.

您可以使用Slf4j和TestWatcher来实现这一点

private static Logger _log = LoggerFactory.getLogger(SampleTest.class.getName());

@Rule
public TestWatcher watchman = new TestWatcher() {
    @Override
    public void starting(final Description method) {
        _log.info("being run..." + method.getMethodName());
    }
};

更简单的方法是将此逻辑放在setUp()和tearDown()方法中。 参考下面的代码，以获得更好的清晰度，

import java.lang.reflect.Method;

@BeforeMethod
void setUp(Method method) {
  log.info("###############################################");
  log.info("Running Test: {}", method.getName());
}

@AfterMethod
void tearDown(Method method) {
  log.info("Finished Test: {}", method.getName());
    log.info("###############################################");
}


@Test
public void testMethodName() {
  // Method logic implementation...
}

以下是上述测试执行的输出，

#############################################################
Running Test: testMethodName
// Logs related to method execution...
Finished Test: testMethodName
#############################################################
