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。

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。
其他回答
@ClassRule
public static TestRule watchman = new TestWatcher() {
@Override
protected void starting( final Description description ) {
String mN = description.getMethodName();
if ( mN == null ) {
mN = "setUpBeforeClass..";
}
final String s = StringTools.toString( "starting..JUnit-Test: %s.%s", description.getClassName(), mN );
System.err.println( s );
}
};
考虑使用SLF4J (Java的简单日志Facade)使用参数化消息提供了一些整洁的改进。将SLF4J与JUnit 4规则实现相结合可以提供更有效的测试类日志记录技术。
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.MethodRule;
import org.junit.rules.TestWatchman;
import org.junit.runners.model.FrameworkMethod;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LoggingTest {
@Rule public MethodRule watchman = new TestWatchman() {
public void starting(FrameworkMethod method) {
logger.info("{} being run...", method.getName());
}
};
final Logger logger =
LoggerFactory.getLogger(LoggingTest.class);
@Test
public void testA() {
}
@Test
public void testB() {
}
}
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) {
}
}
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。
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();
}
}
