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。

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();
}
}
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
#############################################################
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.
@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() {
}
}
