在JUnit 3中，我可以像这样获得当前运行的测试的名称:
public class MyTest extends TestCase
{
public void testSomething()
{
System.out.println("Current test is " + getName());
...
}
}
它会打印“当前测试是testSomething”。
在JUnit 4中是否有任何开箱即用或简单的方法来做到这一点?
背景:显然，我不想只打印测试的名称。我希望加载存储在与测试同名的资源中的特定于测试的数据。你知道，约定比配置更重要。

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());
}
};

JUnit 5通过ExtensionContext
优势:
您可以通过重写afterEach(ExtensionContext上下文)来获得ExtensionContext的附加功能。
public abstract class BaseTest {
protected WebDriver driver;
@RegisterExtension
AfterEachExtension afterEachExtension = new AfterEachExtension();
@BeforeEach
public void beforeEach() {
// Initialise driver
}
@AfterEach
public void afterEach() {
afterEachExtension.setDriver(driver);
}
}
public class AfterEachExtension implements AfterEachCallback {
private WebDriver driver;
public void setDriver(WebDriver driver) {
this.driver = driver;
}
@Override
public void afterEach(ExtensionContext context) {
String testMethodName = context.getTestMethod().orElseThrow().getName();
// Attach test steps, attach scsreenshots on failure only, etc.
driver.quit();
}
}
JUnit 4.7似乎使用TestName-Rule添加了这个特性。看起来这将为您提供方法名称:
import org.junit.Rule;
public class NameRuleTest {
@Rule public TestName name = new TestName();
@Test public void testA() {
assertEquals("testA", name.getMethodName());
}
@Test public void testB() {
assertEquals("testB", name.getMethodName());
}
}
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。
String testName = null;
StackTraceElement[] trace = Thread.currentThread().getStackTrace();
for (int i = trace.length - 1; i > 0; --i) {
StackTraceElement ste = trace[i];
try {
Class<?> cls = Class.forName(ste.getClassName());
Method method = cls.getDeclaredMethod(ste.getMethodName());
Test annotation = method.getAnnotation(Test.class);
if (annotation != null) {
testName = ste.getClassName() + "." + ste.getMethodName();
break;
}
} catch (ClassNotFoundException e) {
} catch (NoSuchMethodException e) {
} catch (SecurityException e) {
}
}
基于前面的评论，并进一步考虑我创建了一个TestWather的扩展，你可以在你的JUnit测试方法中使用:
public class ImportUtilsTest {
private static final Logger LOGGER = Logger.getLogger(ImportUtilsTest.class);
@Rule
public TestWatcher testWatcher = new JUnitHelper(LOGGER);
@Test
public test1(){
...
}
}
测试助手类是下一个:
public class JUnitHelper extends TestWatcher {
private Logger LOGGER;
public JUnitHelper(Logger LOGGER) {
this.LOGGER = LOGGER;
}
@Override
protected void starting(final Description description) {
LOGGER.info("STARTED " + description.getMethodName());
}
@Override
protected void succeeded(Description description) {
LOGGER.info("SUCCESSFUL " + description.getMethodName());
}
@Override
protected void failed(Throwable e, Description description) {
LOGGER.error("FAILURE " + description.getMethodName());
}
}
享受吧!
