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。

@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() {
}
}
@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 );
}
};
JUnit 4没有任何开箱即用的机制让测试用例获得自己的名称(包括在设置和拆卸过程中)。
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();
}
}
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.
