Gets the name implementation method of the test class and method in JUnit

In JUnit's tests, sometimes you need to get the name of the Class or Method you belong to to facilitate logging or something.

In JUnit provides (link: https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/rules/TestName.java) class to do this, in the org. JUnit. Rules:

public class TestName extends TestWatcher {
 private String fName;
 @Override
 protected void starting(Description d) {
  fName = d.getMethodName();
 }
 
 public String getMethodName() {
  return fName;
 }
}

Although TestName only provides the name of the method, it is easy to add the name of the class by modifying TestName slightly as follows:

protected void starting(Description d) {
 fName = d.getClassName() + "." + d.getMethodName();
}

The usage in the test case is:

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());
 }
}

Done!
