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。
当前回答
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());
}
};
其他回答
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.
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
#############################################################
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"));
}
